Peng, Pai;Guo, Shenghui;Li, Linhu;Jin, Hui;Ge, Zhiwei;Guo, Liejin published 《Supercritical water gasification mechanism of polymer-containing oily sludge》 in 2021. The article was appeared in 《International Journal of Hydrogen Energy》. They have made some progress in their research.SDS of cas: 140-66-9 The article mentions the following:

In the offshore petroleum industry, polymer-containing oily sludge (PCOS) hinders oil extraction and causes tremendous hazards to the marine ecol. environment. In this paper, an effective pretreatment method is proposed to break the adhesive structure of PCOS, and the experiments of supercritical water gasification are carried out under the influencing factors including residence time (5-30 min) and temperature (400-750 °C) in batch reactors. The increase of time and temperature all show great promoting effects on gas production Polycyclic aromatic hydrocarbons, including naphthalene and phenanthrene, are considered as the main obstacles for a complete gasification. Carbon gasification efficiency (CE) reaches maximum of 95.82% at 750 °C, 23 MPa for 30 min, while naphthalene makes up 70% of the organic compounds in residual liquid products. The highest hydrogen yield of 19.79 (mol H2/kg of PCOS) is observed in 750 °C for 25 min. A simplified reaction pathway is presented to describe the gaseous products (H2, CO, CO2, CH4). Two intermediates are defined for describing the reaction process bases on the exhaustive study on organic matters in residual liquid products. The results show that the calculated data and the exptl. data have a high degree of fit and tar formation reaction is finished within 10 min. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.

Electric Literature of C8H18O2《Evaluation of TOPKAT, Toxtree, and Derek Nexus in Silico Models for Ocular Irritation and Development of a Knowledge-Based Framework To Improve the Prediction of Severe Irritation》 was published in 2016. The authors were Bhhatarai, Barun;Wilson, Daniel M.;Parks, Amanda K.;Carney, Edward W.;Spencer, Pamela J., and the article was included in《Chemical Research in Toxicology》. The author mentioned the following in the article:

Assessment of ocular irritation is an essential component of any risk assessment. A number of (Q)SARs and expert systems have been developed and are described in the literature. Here, the authors focus on three in silico models (TOPKAT, BfR rulebase implemented in Toxtree, and Derek Nexus) and evaluate their performance using 1644 inhouse and 123 European Center for Toxicol. and Ecotoxicol. of Chems. (ECETOC) compounds with existing in vivo ocular irritation classification data. Overall, the in silico models performed poorly. The best consensus predictions of severe ocular irritants were 52 and 65% for the inhouse and ECETOC compounds, resp. The prediction performance was improved by designing a knowledge-based chem. profiling framework that incorporated physicochem. properties and electrophilic reactivity mechanisms. The utility of the framework was assessed by applying it to the same test sets and three addnl. publicly available in vitro irritation data sets. The prediction of severe ocular irritants was improved to 73-77% if compounds were filtered on the basis of AlogP_MR (hydrophobicity with molar refractivity). The predictivity increased to 74-80% for compounds capable of preferentially undergoing hard electrophilic reactions, such as Schiff base formation and acylation. This research highlights the need for reliable ocular irritation models to be developed that take into account mechanisms of action and individual structural classes. It also demonstrates the value of profiling compounds with respect to their chem. reactivity and physicochem. properties that, in combination with existing models, results in better predictions for severe irritants. The experimental procedure involved many compounds, such as 2,5-Dimethyl-2,5-hexanediol (cas: 110-03-2) .

An, Tingting;Chen, Mengxue;Zu, Zhongqi;Chen, Qi;Lu, Hengqian;Yue, Pengxiang;Gao, Xueling research published 《 Untargeted and targeted metabolomics reveal changes in the chemical constituents of instant dark tea during liquid-state fermentation by Eurotium cristatum》, the research content is summarized as follows. Instant green tea powder was used as raw material to prepare an instant dark tea via liquid-state fermentation by Eurotium cristatum. To understand how the chem. constituents present in fermented green tea develop during fermentation, samples were collected on different days during fermentation for qual. analyses by ultra-performance liquid chromatog.-Q Exactive Orbitrap/Mass spectrometry. Untargeted metabolomics analyses revealed that the levels of original secondary metabolites in the instant green tea changed significantly from day 3 to day 5 during fermentation Targeted metabolomics indicated that the levels of galloylated catechins (GCs) and free amino acids (FAAs) significantly decreased, but the nongalloylated catechins (NGCs), alkaloids, thearubigins and theabrownins increased dramatically after fermentation The changes in the contents of catechins, gallic acid and free amino acids in the instant dark tea samples were pos. related to the DPPH radical scavenging activities in vitro, and the phenolic acids and FAAs were pos. related to the inhibitory effects towards α-glucosidase. These results showed that fermentation by Eurotium cristatum is critical to the formation of certain qualities of instant dark tea.

New progress of cas: 140-66-9 | Science of the Total Environment 2021

4-tert-Octylphenol(cas: 140-66-9) is a common environmental pollutant showing weak estrogenic effects.Recommanded Product: 140-66-9 It has been shown to cause harm to vertebrate male reproductive systems.

Kennes-Veiga, David M.;Vogler, Bernadette;Fenner, Kathrin;Carballa, Marta;Lema, Juan M. published 《Heterotrophic enzymatic biotransformations of organic micropollutants in activated sludge》. The research results were published in《Science of the Total Environment》 in 2021.Recommanded Product: 140-66-9 The article conveys some information:

While heterotrophic microorganisms constitute the major fraction of activated sludge biomass, the role of heterotrophs in the biotransformation of organic micropollutants (OMPs) has not been fully elucidated. Yet, such knowledge is essential, particularly when conceiving novel wastewater treatment plants based on a two-stage process including an A-stage under heterotrophic conditions and a B-stage based on anammox activity. Biotransformation of OMPs in activated sludge is thought to mostly occur cometabolically thanks to the action of low specificity enzymes involved in the metabolism of the primary substrates. For a better understanding of the process, it is important to determine such enzymic activities and the underlying mechanisms involved in OMPs biotransformation. This task has proven to be difficult due to the lack of information about the enzymic processes and the complexity of the biol. systems present in activated sludge. In this paper, a continuous aerobic heterotrophic reactor following 20 OMPs at environmental concentrations was operated to (i) assess the potential of heterotrophs during the cometabolic biotransformation of OMPs, (ii) identify biotransformation reactions catalyzed by aerobic heterotrophs and (iii) predict possible heterotrophic enzymic activities responsible for such biotransformations. Contradicting previous reports on the dominant role of nitrifiers in OMPs removal during activated sludge treatment, the heterotrophic population proved its capacity to biotransform the OMPs to extents equivalent to reported values in nitrifying activated sludge plants. Besides, 12 transformation products potentially formed through the activity of several enzymes present in heterotrophs, including monooxygenases, dioxygenases, hydrolases and transferases, were identified. The experimental procedure involved many compounds, such as 4-tert-Octylphenol (cas: 140-66-9) .

Li, Wenping;Chen, Mingsong;Li, Yanchen;Sun, Jingmeng;Liu, Yi;Guo, Hongwu published 《Improving mildew resistance of soy meal by nano-Ag/TiO2, zinc pyrithione and 4-cumylphenol》 in 2020. The article was appeared in 《Polymers (Basel, Switzerland)》. They have made some progress in their research.Formula: C15H16O The article mentions the following:

As a byproduct from the soybean oil industry, soy meal can be reproduced into value-added products to replace formaldehyde as a plywood adhesive. However, the use of soy meal has been limited by its poor antifungal and antiseptic properties. In this work, three kinds of material, namely nano-Ag/TiO2, zinc pyrithione, and 4-cumylphenol were applied to enhance the mildew resistance of soy meal via breakdown of the cellular structure of mildew. The fungi and mold resistance, morphol., thermal properties, and mechanism of the modified soy meal were evaluated. The success of the antifungal and antiseptic properties was confirmed by Fourier transform IR spectroscopy (FTIR) and SEM. The results indicated that all three kinds of material improved the fungi and mold resistance of soy meal, and sample B, which was modified with a compound of nano-Ag/TiO2 and zinc pyrithione, was the effective antifungal raw material for the soy-based adhesives. FTIR indicated that the great improvement of antifungal properties of soy meal modified with 4-cumylphenol might be caused by the reaction between COO- groups of soy protein. This research can help understand the effects of the chem. modification of nano-Ag/TiO2, zinc pyrithione, and 4-cumylphenol on soy meal, and the modified soy meal exhibits potential for utilization in the plywood adhesive industry. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

Zhao, Jing;Liu, Wei;Chen, Dong;Zhou, Chunli;Song, Yi;Zhang, Yuyu;Ni, Yuanying;Li, Quanhong published 《Microbiological and Physicochemical Analysis of Pumpkin Juice Fermentation by the Basidiomycetous Fungus Ganoderma lucidum》 in 2015. The article was appeared in 《Journal of Food Science》. They have made some progress in their research.Recommanded Product: 80-46-6 The article mentions the following:

A new protocol for processing of pumpkin juice was set up which included fermentation by the basidiomycete Ganoderma lucidum at 28 °C for 7 d. The growth curve of G. lucidum in pumpkin juice was successfully (R2 = 0.99) fitted by a 4-parameter logistic model and the ideal highest biomass was estimated to be 4.79 g/L. G. lucidum was found to have a significant acidification effect on pumpkin juice. The lowest pH (4.05 ± 0.05) and highest total titratable acidity (14.31 ± 0.16 mL 0.1 M NaOH/100 mL) were found on the 4th day during fermentation Sugars in pumpkin juice fermented with G. lucidum showed a significant decrease, especially glucose and fructose. On the contrary, the release of exo-polysaccharides and free amino acids greatly enriched the pumpkin juice. The variation of color index and viscosity also mirrored the above behavior. Based on headspace solid phase microextraction and gas chromatog.-mass spectrometry, 68 volatile compounds were identified, including 17 esters, 14 alcs., 13 Ph compounds, 11 aldehydes, 8 ketones, 3 acids, 1 furan, and 1 benzothiazole. The pumpkin juices fermented for different days were markedly differentiated with principal component anal. and the fermentation process was tentatively divided into 3 periods: the booming (from the 1st to 4th day), steady (from the 5th to 6th day), and decline (the 7th day) period. The experimental procedure involved many compounds, such as 4-tert-Amylphenol (cas: 80-46-6) .

Recommanded Product: 140-66-9《Chemical design of hydrogels with immobilized laccase for the reduction of persistent trace compounds in wastewater》 was published in 2021. The authors were Horn, Christoph;Pospiech, Doris;Allertz, Peter J.;Mueller, Martin;Salchert, Katrin;Hommel, Rolf, and the article was included in《ACS Applied Polymer Materials》. The author mentioned the following in the article:

Hydrogels with immobilized enzymes are increasingly applied in biocatalytic industrial processes. Here, polymer hydrogels containing 2-hydroxyethyl methacrylate (HEMA), itaconic acid (ITA), (2-((2-(ethoxycarbonyl)prop-2-en-1-yl)oxy)ethyl) phosphonic acid (ECPPA), and N,N′-diethyl-1,3-bis(acrylamido)propane (BAAP) as the cross-linker are synthesized by UV-initiated radical polymerization Laccase from Trametes versicolor (LAC) is modified by reaction with itaconic anhydride (ITAn) yielding the LAC-immobilized monomer ITA-LAC with enhanced enzyme activity. ITA-LAC paves the way to an in situ method for enzyme immobilization. Hydrogels with HEMA, ECPPA, and BAAP with stepwise varied chem. composition and functionalization are prepared The influence of the composition on the morphol., the swelling behavior, the mech. stability, and the enzymic activity is studied. The polymerization is monitored by the conversion of double bonds with in situ attenuated total reflection Fourier transform IR (ATR-FTIR) spectroscopy. The polymerization of HEMA is complete after 10 min of UV exposure, whereas hydrogels of HEMA/ITA/ECPPA (85/5/10) with 5 mol % cross-linker require 30 min. These hydrogels are compared with those containing ITA-LAC instead of ITA. The covalent binding of LAC is proven by ATR-FTIR spectroscopy and results in an enhanced enzyme activity. The incorporation of ECPPA induces pH-dependent swelling with an equilibrium degree of swelling of up to 6 at pH 8. Only a weak influence of temperature on the degree of swelling is found. The morphol. strongly depends on the hydrogel composition LAC-ITA hydrogels are characterized by an open morphol. providing access to catalytic centers. The enzyme-immobilized hydrogels are used as granules as well as coatings on porous Al2O3 ceramic substrates as biocatalysts to convert models for organic trace compounds [bisphenol A (BPA), diclofenac, p-chlorophenol (pCP), 17α-ethinylestradiol (EED), triclosan, paracetamol, and 4-tert-octylphenol]. The highest conversion after 24 h in water is achieved for triclosan (>90%), while pCP, BPA, and EED reach a conversion between 60% and 70%. The conversions are even higher in citrate buffer.4-tert-Octylphenol (cas: 140-66-9) were involved in the experimental procedure.

HPLC of Formula: 110-03-2In 2019, Bhaladhare, Sachin;Kim, Soeun;Carter, Kenneth R. published 《Mechanical Properties and Moisture Transport Behavior of Acid-Sensitive Hydrogels》. 《ACS Applied Polymer Materials》published the findings. The article contains the following contents:

Thin hydrogel films containing the acid sensitive cross-linker 2,5-dimethyl-2,5-hexanediol dimethacrylate (DHDMA) were synthesized as part of a larger project to create protective layers against chem. and biol. (CB) threats. In order to operate efficiently as fabric coatings, the mech. and moisture vapor transport properties of these materials must be understood. The hydrogels were composed primarily of poly(ethylene glycol) dimethacrylate (PEGDMA) and 2-hydroxyethyl methacrylate (HEMA) and were prepared by free radical crosslinking polymerization The influence of different compositions of DHDMA, PEGDMA, and HEMA on the moisture vapor transmission rate (MVTR), mech. properties, and swelling properties of PEGDMA/DHDMA/HEMA copolymer hydrogels has been investigated. The characterization by Fourier transform IR (FTIR) spectroscopy confirmed the presence of all monomers used in the gel structure. The hydrogels showed high MVTR, which are comparable to the widely accepted breathable membrane of Gore-Tex fabric and expanded polytetrafluoroethylene (ePTFE). The swelling data indicated that the equilibrium water content depends on the composition of hydrogels. It was found that addition of HEMA into the PEGDMA-based hydrogels was very helpful to improve the swelling properties but decrease in water contact angle. Rheol. study of hydrogels showed that the hydrogels are very stiff and their stiffness increases with increasing PEGDMA content in the hydrogels. And 2,5-Dimethyl-2,5-hexanediol (cas: 110-03-2) was used in the research process.
