Seshasayee, Mahadevan Subramanya;Savage, Phillip E. published 《Oil from plastic via hydrothermal liquefaction: Production and characterization》 in 2020. The article was appeared in 《Applied Energy》. They have made some progress in their research.Application In Synthesis of 2-Hexyl-1-decanol The article mentions the following:

We determined the effect of batch holding time (0.5 h, 1 h) and temperature (350-450°C) on the yield, composition, and quality of oil formed from the hydrothermal treatment of polypropylene (PP), polystyrene (PS), polycarbonate (PC), and polyethylene terephthalate (PET). The highest oil yields for each material ranged from just 16 wt% for PET to 86 wt% for polystyrene. The depolymerization of plastics to produce oil occurs fastest in the supercritical water regime (T > 400°C). The higher heating value (HHV) of the oil from PP and PS (44-45 MJ/kg) is comparable to that of gasoline (HHV ∼ 43.4 MJ/kg). The oil from PC and PET had lower heating values but further treatment to remove oxygen atoms would increase the energy d. Increasing the hydrothermal reaction severity (longer times, higher supercritical temperatures) reduces oil yields but increases heating values. Increasing temperature causes more aromatization in the oil from PP and PS and promotes dehydration reactions during hydrothermal treatment of PET and PC. The oil from PC contained bisphenol-A as a major product. Obtaining such monomers from hydrothermal treatment would provide a revenue stream in addition to oil and thereby improve the process economics. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.

2-Hexyl-1-decanol(cas: 2425-77-6) is a fatty acid that is found in the essential oils of plants and has been shown to have fungicidal properties.Application In Synthesis of 2-Hexyl-1-decanol It has also been shown to inhibit the growth of Candida glabrata when used as a cationic surfactant.

The research results were published in《Science of the Total Environment》 in 2022.Related Products of 140-66-9 The article conveys some information:

Landfill sites have been regarded as a significant source of chems. of emerging concern (CECs) in groundwater. However, our understanding about the compositions of CECs in landfill leachate and adjacent groundwater is still very limited. Here we investigated the CECs in landfill leachates and groundwater of Guangzhou in South China by target, suspect and non-target anal. using high-resolution mass spectrometry (HRMS). A variety of CECs (n = 242), including pharmaceuticals (n = 64), pharmaceutical intermediates (n = 18), personal care products (n = 9), food additives (n = 18), industrial chems. (n = 82, e.g., flame retardants, plasticizers, antioxidants and catalysts), pesticides (n = 26), transformation products (n = 8) and other organic compounds (n = 17) were (tentatively) identified by non-target and suspect screening. 142 CECs were quantitated with target anal., and among them 37, 24 and 27 CECs were detected resp. in the raw leachate (272-1780μg/L), treated leachate (0.25-0.81μg/L) and groundwater (0.10-53.7μg/L). The CECs in the raw leachates were efficiently removed with the removal efficiencies greater than 88.7%. Acesulfame, bisphenol F and ketoprofen were the most abundant compounds in both treated leachate and groundwater. The CECs in groundwater was found most likely to be originated from the landfill sites. Our results highlight the importance of non-target screening in identifying CECs, and reveal the contamination risk of groundwater by landfill leachate. To complete the study, the researchers used 4-tert-Octylphenol (cas: 140-66-9) .

HPLC of Formula: 599-64-4In 2020, Medvedev, Alexander V.;Medvedeva, Lyubov A.;Martsen, Elena;Moeser, Mathew;Gorman, Kristen L.;Lin, Benjamin;Blackwell, Brett;Villeneuve, Daniel L.;Houck, Keith A.;Crofton, Kevin M.;Makarov, Sergei S. published 《Harmonized Cross-Species Assessment of Endocrine and Metabolic Disruptors by Ecotox FACTORIAL Assay》. 《Environmental Science & Technology》published the findings. The article contains the following contents:

Environmental pollution is a threat to humans and wildlife species. Of particular concern are endocrine disrupting chems. (EDCs). An important target of EDCs is nuclear receptors (NRs) that control endocrine and metabolic responses through transcriptional regulation. Owing in part to structural differences of NRs, adverse effects of EDCs vary significantly among species. Here, we describe a multiplexed reporter assay (the Ecotox FACTORIAL) enabling parallel assessment of compounds’ effects on estrogen, androgen, thyroid, and PPARγ receptors of representative mammals, birds, reptiles, amphibians, and fish. The Ecotox FACTORIAL is a single-well assay comprising a set of species-specific, one-hybrid GAL4-NR reporter constructs transiently transfected into test cells. To harmonize cross-species assessments, we used a combination of two approaches. First, we used the same type of test cells for all reporters; second, we implemented a parallel detection of reporter RNAs. The assay demonstrated excellent quality, reproducibility, and insignificant intra-assay variability. Importantly, the EC₅₀ values for NR ligands were consistent with those reported for conventional assays. Using the assay allowed ranking the hazard potential of environmental pollutants (e.g., bisphenols, polycyclic aromatic hydrocarbons, and synthetic progestins) across species. Furthermore, the assay permitted detecting taxa-specific effects of surface water samples. Therefore, the Ecotox FACTORIAL enables harmonized assessment of the endocrine and metabolic disrupting activity of chems. and surface water in humans as well as in wildlife species. And 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) was used in the research process.

Safety of 2-Hexyl-1-decanol《Bithieno[3,4-c]pyrrole-4,6-dione-Mediated Crystallinity in Large-Bandgap Polymer Donors Directs Charge Transportation and Recombination in Efficient Nonfullerene Polymer Solar Cells》 was published in 2020. The authors were Zhao, Jiaji;Li, Qingduan;Liu, Shengjian;Cao, Zhixiong;Jiao, Xuechen;Cai, Yue-Peng;Huang, Fei, and the article was included in《ACS Energy Letters》. The author mentioned the following in the article:

Solution-processed nonfullerene bulk-heterojunction (BHJ) polymer solar cells (PSCs), which are composed of polymer donors and organic acceptors, are proven to manifest promising performance and long-term stability. In this concise contribution, bithieno[3,4-c]pyrrole-4,6-dione (BiTPD), which is a TPD derivative but presents a large planar structure and strong electron-withdrawing ability, was used to construct a large-bandgap polymer donor PBiTPD. Results show that the polymer donor PBiTPD realized power conversion efficiency (PCE) as high as 14.2% in fullerene-free BHJ solar cells. Larger ionization potential value, more favorable face-on backbone orientation, and stronger crystallinity were concurrently obtained in PBiTPD. Correspondingly, improved and more balanced charge transportation; less nongeminate and trap-assisted recombination losses; and thus high fill factor (FF) of 67%, short-circuit c.d. (Jsc) of 25.6 mA·cm^-2, and high open-circuit voltage (Voc) of 0.83 V were concurrently achieved in PBiTPD-based devices. PBiTPD does clear the way for a novel and promising class of large-bandgap polymer donor candidates.2-Hexyl-1-decanol (cas: 2425-77-6) were involved in the experimental procedure.

Yang, Lu;Wenzel, Thomas;Williamson, R. Thomas;Christensen, Melodie;Schafer, Wes;Welch, Christopher J. published 《Expedited Selection of NMR Chiral Solvating Agents for Determination of Enantiopurity》. The research results were published in《ACS Central Science》 in 2016.Related Products of 579-43-1 The article conveys some information:

The use of NMR chiral solvating agents (CSAs) for the anal. of enantiopurity was known for decades, but was supplanted in recent years by chromatog. enantioseparation technol. While chromatog. methods for the anal. of enantiopurity are now commonplace and easy to implement, there are still individual compounds and entire classes of analytes where enantioseparation can prove extremely difficult, notably, compounds that are chiral by virtue of very subtle differences such as isotopic substitution or small differences in alkyl chain length. NMR anal. using CSAs can often be useful for such problems, but the traditional approach to selection of an appropriate CSA and the development of an NMR-based anal. method often involves a trial-and-error approach that can be relatively slow and tedious. The authors describe a high-throughput experimentation approach to the selection of NMR CSAs that employs automation-enabled screening of prepared libraries of CSAs in a systematic fashion. This approach affords excellent results for a standard set of enantioenriched compounds, providing a valuable comparative data set for the effectiveness of CSAs for different classes of compounds The technique was successfully applied to challenging pharmaceutical development problems that are not amenable to chromatog. solutions Overall, this methodol. provides a rapid and powerful approach for studying enantiopurity that compliments and augments conventional chromatog. approaches.rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) were involved in the experimental procedure.

Hu, Shuangling;Chen, Qinghua;Guo, Fei;Wang, Mingle;Zhao, Hua;Wang, Yu;Ni, Dejiang;Wang, Pu published 《(Z)-3-Hexen-1-ol accumulation enhances hyperosmotic stress tolerance in Camellia sinensis》 in 2020. The article was appeared in 《Plant Molecular Biology》. They have made some progress in their research.Quality Control of 2-Hexyl-1-decanol The article mentions the following:

Volatile components in fresh leaves are involved in the regulation of many stress responses, such as insect damage, fungal infection, high temperature Here, we found that 7-day hyperosmotic treatment specifically led to the accumulation of (Z)-3-hexen-1-ol, (E)-2-hexenal and Me salicylate. (Z)-3-hexen-1-ol pretreatment dramatically enhanced the hyperosmotic stress tolerance of tea plants and decreased stomatal conductance, whereas (E)-2-hexenal and Me salicylate pretreatments did not exhibit. qRT-PCR anal. revealed that exogenous ABA induced the expressions of related enzyme genes, and (Z)-3-hexen-1-ol could up-regulate the expressions of many DREB and RD genes. Moreover, exogenous (Z)-3-hexen-1-ol tremendously induced the expressions of specific LOX and ADH genes within 24 h. Taken together, hyperosmotic stress induced (Z)-3-hexen-1-ol accumulation in tea plant via LOX, HPL and ADH genes, (Z)-3-hexen-1-ol could dramatically enhance the hyperosmotic stress tolerance via the decrease of stomatal conductance and MDA, accumulation of ABA and proline, activation of DREB and RD gene expressions. Key message: Hyperosmotic stress induced (Z)-3-hexen-1-ol accumulation in Camellia sinensis via up-regulation of most LOX, HPL and ADH genes, while (Z)-3-hexen-1-ol could dramatically enhance the hyperosmotic stress tolerance via the decrease of stomatal conductance, accumulation of proline, activation of DREB and RD gene expressions, and probably pos. feedback regulation of LOXs and ADHs. To complete the study, the researchers used 2-Hexyl-1-decanol (cas: 2425-77-6) .
