The article was appeared in 《Journal of Cleaner Production》. They have made some progress in their research.Reference of 2-Hexyl-1-decanol The article mentions the following:

In this study, thermo-chem. decomposition of Refuse Derived Fuel (RDF) from municipal solid waste pre-treatment plant has been conducted in pyrolytic conditions. Due to high heterogeneity, individual RDF samples are not necessarily representative of the full variety of different components present. To overcome this, five different samples of RDF with varying compositions were treated in a rotary kiln reactor. RDF feed has been characterized based on the amount of biomass and plastic content. Product (oil & char) composition and quality were analyzed using different characterization techniques. It was observed that the quality of pyrolysis products varied with the feed composition and operating temperature Maximum oil yield of oil 43% was obtained from RDF containing 77% of plastics at 500 °C. This study showed that the interaction of RDF components has a major role in the pyrolysis oil composition The oil phase mainly consisted of n-aliphatic, branched aliphatic compounds and primary alcs. while, the aqueous phase consisted of organic acids, furans, methanol, phenols, and their derivatives along with ketones. At higher temperatures, the phenolic compounds decreased and the alc. content was found to increase. Using solvent extraction, phenolic compounds were extracted with hexane while, ketones and acids were extracted using acetone. With high plastic content (85%), the char yield reduced from 55% to 30% with increase in temperature Char samples consisted of different functional groups such as -OH and -COOH along with the micronutrients such as K, Mg and P, with pH in the range of 7.8-9.5 making it suitable for soil applications. Detailed chem. composition anal. of pyrolysis oil and char is the key to design pyrolysis process and evaluating its importance for producing the value-added chems.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Shi, Yu;Liu, Chang;Zhuo, Jiankun;Yao, Qiang published 《Investigation of a Ni-Modified MCM-41 Catalyst for the Reduction of Oxygenates and Carbon Deposits during the Co-Pyrolysis of Cellulose and Polypropylene》 in 2020. The article was appeared in 《ACS Omega》. They have made some progress in their research.HPLC of Formula: 2425-77-6 The article mentions the following:

Catalytic fast co-pyrolysis of biomass and plastic is an effective method to achieve high-quality bio-oil production In this work, (Ni)-MCM-41 catalysts with different Ni loadings were prepared and characterized in detail by using a variety of advanced anal. techniques, and the effects on the catalytic performance were analyzed by micropyrolysis with gas chromatog. mass spectrometry (Py-GC/MS) and thermogravimetry-Fourier transform IR spectroscopy (TG-FTIR) methods. The results showed that an appropriate amount of Ni addition can effectively modulate the physicochem. properties of MCM-41. For a Ni loading of 25.1 wt % (Cat-C), the catalyst showed an optimal catalytic performance, a decrease in the proportion of oxygenated compounds in the product from 35.6 (MCM-41) to 13.4%, and an increase in the relative total amount of olefins plus aromatics from 62.2 (MCM-41) to 84.6%. The excellent catalytic performance of Cat-C can be ascribed to a balancing of its proper phys. structural properties, appropriate acidity, strong metal-carrier interaction, high metal dispersion, and excellent compatibility balance between active and acidic sites.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Rombola, Alessandro G.;Torri, Cristian;Vassura, Ivano;Venturini, Elisa;Reggiani, Roberto;Fabbri, Daniele published 《Effect of biochar amendment on organic matter and dissolved organic matter composition of agricultural soils from a two-year field experiment》 in 2022. The article was appeared in 《Science of the Total Environment》. They have made some progress in their research.Electric Literature of C14H22O The article mentions the following:

Dissolved organic matter (DOM) is an important organic matter fraction that plays a key role in many biol. and chem. processes in soil. The effect of biochar addition on the content and composition of soil organic matter (SOM) and DOM in an agricultural soil in Italy was investigated within a two-year period. UV-Vis spectroscopy and anal. pyrolysis have been applied to study complex components in DOM soil samples. Addnl., anal. pyrolysis was used to provide qual. information of SOM at mol. level and the properties of biochar before and one year after amendment. A method was developed to quantify biochar levels by thermogravimetric anal. that enabled to identify deviations from the amendment rate. The water-soluble organic carbon (WSOC) concentrations in the amended soils were significantly lower than those in the control soils, indicating that biochar decreased the leaching of DOM. DOM in treated soils was characterized by a higher aromatic character according to anal. pyrolysis and UV-Vis spectroscopy. Moreover, a relatively high abundance of compounds with N was observed in pyrolyzates of treated soils, suggesting that biochar increased the proportion of microbial DOM. The results from thermal and spectroscopy techniques are consistent in highlighting significant changes in DOM levels and composition due to biochar application with important effects on soil carbon storage and cycling. And 4-tert-Octylphenol (cas: 140-66-9) was used in the research process.

The article contains the following contents:

Stable doping of indacenodithieno[3,2-b]thiophene (IDTT) structures enables easy color tuning and significant improvement in the charge storage capacity of electrochromic polymers, making use of their full potential as electrochromic supercapacitors and in other emerging hybrid applications. Here, the IDTT structure is copolymerized with four different donor-acceptor-donor (DAD) units, with subtle changes in their electron-donating and electron-withdrawing characters, so as to obtain four different donor-acceptor copolymers. The polymers attain important form factor requirements for electrochromic supercapacitors: desired switching between achromatic black and transparent states (L*a*b* 45.9, -3.1, -4.2/86.7, -2.2, and -2.7 for PIDTT-TBT), high optical contrast (72% for PIDTT-TBzT), and excellent electrochem. redox stability (I^red/I^oxca. 1.0 for PIDTT-EBE). Poly[indacenodithieno[3,2-b]thiophene-2,8-diyl-alt-4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-(2-hexyldecyl)-2H-benzo[d][1,2,3]triazole-7,7′-diyl] (PIDTT-EBzE) stands out as delivering simultaneously a high contrast (69%) and doping level (>100%) and specific capacitance (260 F g^-1). This work introduces IDTT-based polymers as bifunctional electro-optical materials for potential use in color-tailored, color-indicating, and self-regulating smart energy systems. The experimental procedure involved many compounds, such as 2-Hexyl-1-decanol (cas: 2425-77-6) .

Klein, Tobias;Lenahan, Frances D.;Kerscher, Manuel;Rausch, Michael H.;Economou, Ioannis G.;Koller, Thomas M.;Froeba, Andreas P. published 《Characterization of Long Linear and Branched Alkanes and Alcohols for Temperatures up to 573.15 K by Surface Light Scattering and Molecular Dynamics Simulations》 in 2020. The article was appeared in 《Journal of Physical Chemistry B》. They have made some progress in their research.HPLC of Formula: 2425-77-6 The article mentions the following:

This work contributes to the characterization of long linear and branched alkanes and alcs. via the determination of their thermophys. properties up to temperatures of 573.15 K. For this, exptl. techniques including surface light scattering (SLS) and mol. dynamics (MD) simulations were used under equilibrium conditions to analyze the influences of chain length, branching, and hydroxylation on liquid d., liquid viscosity, and surface tension. For probing these effects, 12 pure model systems given by the linear alkanes n-dodecane, n-hexadecane, n-octacosane, n-triacontane, and n-tetracontane, the linear alcs. 1-dodecanol, 1-hexadecanol, and 1,12-dodecanediol, the branched alkanes 2,2,4,4,6,8,8-heptamethylnonane (HMN) and 2,6,10,15,19,23-hexamethyltetracosane (squalane), and the branched alcs. 2-butyl-1-octanol and 2-hexyl-1-decanol were investigated at or close to saturation conditions at temperatures between 298.15 and 573.15 K. Based on the exptl. results for the liquid densities, liquid viscosities, and surface tensions with average expanded uncertainties (k = 2) of 0.061, 2.1, and 2.6%, resp., the performance of the three commonly employed force fields (FFs) TraPPE, MARTINI, and L-OPLS was assessed in MD simulations. To improve the simulation results for the best-performing all-atom L-OPLS FF at larger temperatures, a modified version was suggested. This incorporates a temperature dependence for the energy parameters of the Lennard-Jones potential obtained by calibrating only against the exptl. liquid d. data of n-dodecane. By transferring this approach to all other systems studied, the modified L-OPLS FF shows now a distinctly better representation of the equilibrium and transport properties of the long alkanes and alcs., especially at high temperatures And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.

Application of 599-64-4In 2020, Kirchnawy, Christian;Hager, Fiona;Osorio Piniella, Veronica;Jeschko, Mathias;Washuettl, Michael;Mertl, Johannes;Mathieu-Huart, Aurelie;Rousselle, Christophe published 《Potential endocrine disrupting properties of toys for babies and infants》. 《PLoS One》published the findings. The article contains the following contents:

The purpose of this study was to measure hormonal activity of substances leaching from toys and to identify potential endocrine disruptors causing that activity. For this purpose, migration experiments of toys were conducted in saliva simulants. Chem. trace anal.-namely, GC-MS and HPLC-MS- was used to identify which compounds may be responsible for endocrine activity in the sample migrates. Nine out of 18 tested toys showed significant estrogenic activity. For two samples, the detected estrogenic activity could be well explained by detecting the known endocrine active substance bisphenol A (BPA). For all identified substances, including BPA, a risk assessment for human health was performed by comparing the exposure dose, calculated based on the determined substance concentration, to toxicol. reference values. Using worst-case scenarios, the exposure to BPA by mouthing of the two estrogen active, BPA-containing toys could be above the temporary TDI that EFSA has calculated This demonstrates that some toys could significantly contribute to the total exposure to BPA of babies and infants. For seven out of nine estrogen active samples, the source of the estrogen activity could not be explained by anal. for 41 known or suspected endocrine active substances in plastic, indicating that the estrogen activities were caused by currently unknown endocrine active substances, or by endocrine active substances that would currently not be suspected in toys. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

The article was appeared in 《Xiandai Shipin Keji》. They have made some progress in their research.COA of Formula: C16H34O The article mentions the following:

The effects of heating methods on the quality and volatile substance contents of frozen red bean paste buns were examined Frozen red bean paste buns were heated using three methods, namely, steaming using a multifunction oven, steaming using a traditional food steamer, and microwave heating. Changes in quality parameters such as water content, texture, color, sp. volume, heating characteristics, and volatile flavor substance contents of the heated red bean paste buns were determined The results showed that heating methods had significant effects on the quality and relative contents of volatile flavor substances of frozen red bean paste buns (p<0.05). According to water content anal., microwave heating had the smallest effect in the proton migration rate. Texture anal. revealed that heating using a traditional food steamer yielded the least hard and chewy buns. L* values of the buns heated using microwave were the lowest whereas their a* values were the highest. The sp. volume of buns heated using a traditional food steamer was the largest, with the lowest water loss rate. In addition, buns heated using microwave had the highest pH values. Solid phase microextraction and gas chromatog.-mass spectrometry assays identified 52, 55, and 54 types of volatile flavor substances from buns heated using the three methods. The identified volatile flavor substances were mainly alcs., acids, esters, aldehydes, ketones, and phenols. The results further indicated that heating using a traditional food steamer was the most suitable method for frozen dough. These findings shall provide a theor. basis for the selection and control of heating methods for frozen dough.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Bubmann, Tobias;Seidel, Andreas;Ruckdaeschel, Holger;Altstaedt, Volker published 《Transparent PC/PMMA Blends with Enhanced Mechanical Properties via Reactive Compounding of Functionalized Polymers》. The research results were published in《Polymers (Basel, Switzerland)》 in 2022.Safety of 4-(2-Phenylpropan-2-yl)phenol The article conveys some information:

Reactive compounding of terminally phenolic OH-functionalized polycarbonate (PC) with epoxy-functionalized polymethylmethacrylate (PMMA) prepared by copolymerization with glycidyl methacrylate was investigated. It was spectroscopically demonstrated that a PC/PMMA copolymer was formed during the melt reaction of the functional groups. Zirconium acetylacetonate could catalytically accelerate this reaction. Correlations of the phenomenol. (optical and mech.) properties with the mol. level and mesoscopic (morphol.) structure were discussed. By the investigated reactive compounding process, transparent PC/PMMA blends with two-phase morphologies were obtained in a continuous twin-screw extruder, which, for the first time, combined the high transmission of visible light with excellent mech. performance (e.g., synergistically improved tensile and flexural strength and high scratch resistance). The transparency strongly depended on (a) the degree of functionalization in both PC and PMMA, (b) the presence of the catalyst, and (c) the residence time of the compounding process. The in-situ-formed PC/PMMA copolymer influenced the observed macroscopic properties by (a) a decrease in the interphase tension, leading to improved and stabilized phase dispersion, (b) the formation of a continuous gradient of the polymer composition and thus of the optical refractive indexes in a diffuse mesoscopic interphase layer separating the PC and PMMA phases, and (c) an increase in the phase adhesion between PC and PMMA due to mech. polymer chain entanglement in this interphase. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
