Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 647-42-7, formula is C8H5F13O, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Formula: C8H5F13O
Zhou, Rong;Jin, Yong;Lai, Shuangquan;Shi, Liangjie;Bai, Long;Peng, Zhangyi research published 《 A novel composite retanning system based on pH-responsive hydrogen bonding and hydrophobic interaction for cleaner leather processing》, the research content is summarized as follows. Aldehyde-tanned leather is one of the promising choices to avoid the widespread chrome pollution in leather industry. Due to the lack of metal ions, the aldehyde-tanned leather not able to effectively fix traditional anionic retanning materials, which seriously affects the quality of aldehyde-tanned leather. Herein, a novel composite retanning system consisting of acrylic resin (AR) and F6-600 (a nonionic fluorinated surfactant with poly(ethylene oxide) (PEO)) was constructed, which breaks through the dependence of conventional leather materials on metal ions in terms of fixation. The main acting mechanism is that at the final stage of retanning, after reducing the float pH, pH-responsive hydrogen bonding and hydrophobic interaction synergistically drive AR/F6-600 to self-assemble into bigger polymer composite aggregates, and then these aggregates are forced to deposit and fill in leather fiber gaps, thus obtaining more desirable retanning results. Furthermore, AR/F6-600 composite retanning system is eco-friendly. The AR/F6-600 retanned leather has lower free formaldehyde content, better biodegradability, and higher uptake rates for subsequent dye and fatliquoring agent, which can further eliminate the threat of formaldehyde to health, accelerate the degradation of waste leather in the nature, and reduce the chem. residual in wastewater, resp. Consequently, this novel retanning system will benefit to satisfy evolving demands for related technologies toward cleaner leather production
647-42-7, 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctan-1-ol, also known as 1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol , is a useful research compound. Its molecular formula is C8H5F13O and its molecular weight is 364.1 g/mol. The purity is usually 95%.
1H,1H, 2H, 2H-Tridecafluoro-1-n-octanol is a material used to improve nanotube composites. It is also used in the synthesis of a recyclable fluorous hydrazine carbothioate compound with NCS to catalyze the acetalization of aldehydes.
1H,1H,2H,2H-Tridecafluoro-1-n-octanol is a potent and selective halogenated hydrocarbon. It binds to DNA at the dinucleotide phosphate site, which is an important site for polymerase chain reaction (PCR) activation. 1HFN has been shown to be more effective than other halogenated hydrocarbons in vitro assays on rat liver microsomes. It has been used as an additive in wastewater treatment to remove organic contaminants and metal ions. In vivo studies have been carried out in CD-1 mice to determine the effects of 1HFN on the liver and kidneys; these studies showed no toxicological effects on these organs. 1HFN also has been shown to inhibit enzymes such as cytochrome P450 and monoamine oxidase B that are involved in drug metabolism and may lead to adverse reactions with drugs metabolized by these enzymes., Formula: C8H5F13O
