COA of Formula: C23H32O2In 2021, Tang, Shuqin;Chen, Yukun;Song, Guixian;Liu, Xiaotu;Shi, Yumeng;Xie, Qitong;Chen, Da published 《A Cocktail of Industrial Chemicals in Lipstick and Nail Polish: Profiles and Health Implications》. 《Environmental Science & Technology Letters》published the findings. The article contains the following contents:

Beauty products contain various industrial chems. to increase their functionality and appearance. The frequent use of beauty products may increase human exposure to industrial chems., but to date, their chem. components remain poorly characterized. Our work characterized the chem. components in lipstick and nail polish by screening for a total of 231 chems. from seven categories, including organophosphate esters (OPEs), phthalate esters (PAEs), non-PAE plasticizers, bisphenol analogs, parabens, UV stabilizers, and antioxidants. Their total concentrations ranged from 38.9 to 3810 μg/g (median of 193 μg/g) and from 18.6 to 1910 μg/g (307 μg/g) in lipstick (n = 34) and nail polish (n = 15), resp. The chem. compositions differed between lipstick and nail polish, but non-PAE plasticizers generally dominated over other groups of chems. A number of emerging plasticizers, OPEs, and UV stabilizers have rarely been reported in personal care products or environmental samples but were found at very high levels in beauty products, raising concern about their environmental release and human exposure risk. Although the employment of a hazard quotient approach suggested low health risks for exposure to industrial chems. from the use of beauty products, potential mixture effects from the chem. cocktail and occupational exposure to beauty products should not be overlooked. To complete the study, the researchers used 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

Qiao, Juanjuan;Lu, Gengyu;Wu, Gang;Liu, Hui;Wang, Wanli;Zhang, Tianmao;Xie, Guoyong;Qin, Minjian published 《Influence of different pretreatments and drying methods on the chemical compositions and bioactivities of Smilacis Glabrae Rhizoma》. The research results were published in《Chinese Medicine (London, United Kingdom)》 in 2022.Formula: C23H32O2 The article conveys some information:

The processing of medicinal plant materials is one of the important factors influencing the components and biol. activities of TCMs. Smilax glabra Roxb. is an herbal vine widely distributed in China, and its dried rhizome (Smilacis Glabrae Rhizoma, SGR) is often used in traditional medicines and functional foods. The processing methods of fresh cutting for SGR slices have been included in ancient Chinese herbal works, some local standards of TCMs, and the current Chinese Pharmacopoeia. Nevertheless, to date, the scientific basis for the processing of fresh medicinal materials for SGR slices has not been revealed. To optimize the processing method for preparing SGR slices from the fresh rhizomes, the chem. compositions of the un-pretreated and pretreated (boiling, steaming) samples before and after drying (sun-drying, shade-drying, oven-drying), and the contents of astilbin isomers in dried SGR were analyzed by UHPLC-Q-TOF-MS/MS and UHPLC-DAD methods, resp. Then, the antioxidant, anti-inflammatory, xanthine oxidase and α-glucosidase inhibitory activities of the prepared SGR slices were investigated by biol. assays. A total of fifty-two compounds were identified from the un-pretreated and pretreated samples and a total of forty-nine compounds were identified from the subsequently dried samples. After pretreated by boiling and steaming, the contents of neoastilbin, neoisoastilbin, and isoastilbin in the prepared samples all increased. As a quality marker of SGR, the content of astilbin was unchanged or decreased slightly compared with that in the un-pretreated samples. During the drying process, the contents of the four astilbin stereoisomers in the un-pretreated samples increased significantly, while those in the pretreated samples had a slight increase or decrease. The effects of different processing methods were sorted according to the bioactivities of the prepared SGR. As a result, SGR slices prepared with no pretreatment followed by a sun-drying process have a higher astilbin content, better bioactivities and more energy savings, representing the optimum processing method for SGR slices. This study reveals the scientific basis for the processing of fresh medicinal materials for SGR slices. The results provide scientific information for the quality control of SGR and its rational applications in herbal medicines and functional foods. And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.

Qin, Junhao;Zeng, Shuqing;Wang, Xi;Lin, Chuxia published 《Generation of micro(nano)plastics and migration of plastic additives from Poly(vinyl chloride) in water under radiation-free ambient conditions》. The research results were published in《Chemosphere》 in 2022.Application In Synthesis of 2,2-Methylenebis(6-tert-butyl-p-cresol) The article conveys some information:

A batch experiment was conducted to observe the liberation of micro- and nano-sized plastic particles and plastic additive-originated organic compounds from poly(vinyl chloride) under radiation-free ambient conditions. The weathering of PVC films in deionized water resulted in isolated pockets of surface erosion. Addnl. OH from Fenton reaction enhanced PVC degradation and caused cavity erosion. The detachment of plastic fragments from the PVC film surfaces was driven by autocatalyzed oxidative degradation Over 90% of micro-sized plastic particles were <60 μm in length. The detached plastic fragments underwent intensified weathering, which involved strong dehydrochlorination and oxidative degradation Further fragmentation of micro-sized particles into nano-sized particles was driven by oxidative degradation with complete dehydrochlorination being achieved following formation of nanoplastics. 20 organic compounds released from the PVC films into the solutions were identified. And some of them can be clearly linked to common plastic additives. In the presence of addnl. OH, the coarser nanoplastic particles (>500 nm) tended to be rapidly disintegrated into finer plastic particles (<500 nm), while the finest fraction of nanoplastics (<100 nm) could be completely decomposed and disappeared from the filtrates. The micro(nano)plastics generated from the PVC weathering were highly irregular in shape. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

The research results were published in《Angewandte Chemie, International Edition》 in 2022.SDS of cas: 119-47-1 The article conveys some information:

A novel approach for various asym. transformations of cyclic enones, e.g., 2-cyclohepten-1-one has been described. The combination of readily accessible chiral diamines and sterically demanding flexible phosphoric acids resulted in a simple and highly tunable catalyst framework. The careful optimization of the catalyst components led to the identification of a particularly powerful and multi-purpose organocatalyst, which was successfully applied for asym. epoxidations, aziridinations, aza-Michael-initiated cyclizations, as well as for a novel Robinson-like Michael-initiated ring closure/aldol cyclization. High catalytic activities and excellent stereocontrol were observed for all four reaction types, indicating the excellent versatility of the catalytic system. Furthermore, a simple change in the diamine’s configuration provided easy access to both product antipodes in all cases. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

The authors were Ge, Zhenzhen;Wang, Weijing;Xu, Mingyue;Gao, Shanshan;Zhao, Yuxiang;Wei, Xiaopeng;Zhao, Guangyuan;Zong, Wei, and the article was included in《Journal of the Science of Food and Agriculture》. The author mentioned the following in the article:

Although traditional fermented noodles possess high eating quality, it is difficult to realize large-scale industrialization as a result of the complexity of spontaneous fermentation In present study, com. Lactobacillus plantarum and Saccharomyces cerevisiae were applied in the preparation of fermented noodles. The changes in the structural characteristics and aroma components of noodles after fermentation were investigated via SEM (SEM), Fourier transform IR spectroscopy (FTIR), low-field magenetic resonance imaging, electronic nose, and simultaneous distillation and extraction/gas chromatog.-mass spectrometry (GC-MS) anal. SEM images revealed that co-fermentation of the L. plantarum and S. cerevisiae for 10-40 min enhanced the continuity of the gluten network and promoted the formation of pores. FTIR spectra anal. showed that the co-fermentation increased significantly (P < 0.05) the proportion of α-helixes of noodles gluten protein, enhancing the orderliness of the mol. structure of protein. After fermentation for 10-40 min, the signal d. of hydrogen protons increased from the surface to the core, indicating that the water in the noodles migrated inward during a short fermentation process. The results of multivariate statistical anal. demonstrated that the main aroma differences between unfermented and fermented noodles were mainly in hydrocarbons, aromatic compounds and inorganic sulfides. GC-MS anal. indicated that the main volatile compounds detected were 2, 4-di-tert-butylphenol, bis (2-ethylhexyl) adipate, Bu acetate, di-Bu phthalate, dioctyl terephthalate, bis (2-ethylhexyl) phthalate, pentanol and 2-pentylfuran, etc. Co-fermentation with L. plantarum and S. cerevisiae improved the structure of gluten network and imparted more desirable volatile components to wheat noodles. 2022 Society of Chem.

Quality Control of 2,2-Methylenebis(6-tert-butyl-p-cresol)《Experimental investigation on the oxidation of printing ink wastewater under hydrothermal flames》 was published in 2021. The authors were Zhang, Fengming;Li, Yufeng;Liang, Zhaojian;Wu, Tong;Huang, Yingfei, and the article was included in《Journal of Environmental Chemical Engineering》. The author mentioned the following in the article:

Printing ink wastewater has a strong color and contains high salinity and high concentrations of complex organic compounds, posting a severe threat to the ecol. environment and human health. In this work, supercritical water oxidation of printing ink wastewater is performed within a transpiring wall reactor (TWR) to avoid corrosion and salt plugging issues. The high concentration of organic matter in printing ink wastewater is used to form hydrothermal flames for enhanced degradation Flame temperatures, gaseous and aqueous products characteristics, as well as the anti-corrosion and salt plugging performance of the reactor, are obtained. A remarkable temperature fluctuation due to the multi-component systems indicates the instability of hydrothermal flame. The salt recovery rate of 94.56% and the integrity of the porous tube inner wall indicate that TWR has a good performance in terms of anti-corrosion and salt plugging. Under typical conditions, the removal rates for COD, total nitrogen, and color are 99.52%, 70.07%, and 97.89%, resp. Alkanes, nitrogenous compounds, benzodiazepines, and heterocyclic compounds in the aqueous products, and CO, H₂, NH₃, and CH₄ in the gaseous products are the main intermediate products of printing ink wastewater under hydrothermal flames. Ammonia nitrogen, as the main intermediate product, inhibits the complete oxidation of nitrogenous organic compounds Addnl., higher KNO₃ concentrations promote the complete oxidation of nitrogenous organic compounds, while higher NaOH concentrations can increase the pH value and slightly facilitate degradation In addition, higher feed flow rates prevent deposition and adhesion of additives that occur at high concentrations And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.

Name: 2,2-Methylenebis(6-tert-butyl-p-cresol)In 2020, Seo, Sung-Hee;Kwon, Hye-Ok;Park, Min-Kyu;Lee, In-Seok;Choi, Sung-Deuk published 《Contamination characteristics of polycyclic aromatic hydrocarbons in river and coastal sediments collected from the multi-industrial city of Ulsan, South Korea》. 《Marine Pollution Bulletin》published the findings. The article contains the following contents:

River and coastal sediments were collected at 17 stations in Ulsan, the largest industrial city in South Korea, to evaluate the levels, profiles, emission sources, and spatial distribution of polycyclic aromatic hydrocarbons (PAHs). The mean concentration of Σ₁₆ PAHs was 722 ng/g, and fluoranthene was a predominant compound PAHs with 4-6 rings showed higher proportions than PAHs with 2-3 rings. The stations located near industrial complexes showed elevated levels of indicator compounds for petroleum, coal, coke, and fuel combustion. Therefore, petrochem. industries, coal pier, non-ferrous industries, and vehicles were identified as the emission sources. As industrialization and urbanization progressed, an increase in PAH levels and profile changes were observed as a result of the increasing industrial fuel consumption and the increasing number of vehicles. This is the first study that confirmed the change of PAHs in sediment caused by the change of emission sources over time in Ulsan. And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.

The research results were published in《Chemical Engineering Journal (Amsterdam, Netherlands)》 in 2021.Name: 2,2-Methylenebis(6-tert-butyl-p-cresol) The article conveys some information:

High ionic conductivity, strong stability to lithium metal, convenient preparation and good adaptability to cathodes are the important prerequisites for the practical application of solid-state electrolytes (SE). In this work, an environment-friendly poly(1,3-dioxolane) (PDOL) solid electrolyte membrane was for the first-time prepared by a rapid surface-initiating 1,3-dioxolane (DOL) polymeration process under the interaction of substrate and initiator. The -SiO3, -CaO5 and -NaO3 groups on the surface of glass substrate can react with the oxygen atoms on the DOL ring, initiate the rings opening and polymerizing to be long chains under the action of LiPF6, which provides an efficient and environment-friendly preparation method for PDOL membrane without any organic solvent release, and the monomer conversion rate of the DOL reaches 97.6%. This highly polymerized PDOL electrolyte is friendly to the lithium metal environment and shows strong stability, the Li/SE/Li cell can run stably for nearly 4000 h at a c.d. of 0.3 mA/cm2. High electrochem. stability window up to 5.0 V enables PDOL electrolyte friendly adapt to various cathode environments including sulfur (S) and LiFePO4, and LiCoO2 and Li(Ni0.6Co0.2Mn0.2)O2 (NCM622). The assembled NCM622/SE/Li solid-state soft-pack battery can be cycled for 300 cycles at 0.5 C with the capacity retention of 85%. This PDOL electrolyte membrane shows a high promising com. application prospect due to its friendly and high-efficiency polymerization process and strong adaptability to electrodes.2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) were involved in the experimental procedure.
