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. , Electric Literature of 647-42-7
Ren, Longfang;Tang, Zheng;Geng, Jin;Xing, Zhengguo;Qiang, Taotao research published 《 Improvement for yellowing resistance of aromatic PU film by fluoro alcohol termination and branching modification》, the research content is summarized as follows. The fluoro alc.-terminated branched polyurethanes with different fluorine content (FABPU-0, FABPU-1 and FABPU-2) was successfully synthesized via step-by-step polymerization in which polytetramethylene oxide glycol (PTMG-2000) and 4,4′-diphenylmethane diisocyanate (MDI) were used as raw materials, 1,4- butanediol (BDO) as the chain extender, pentaerythritol as crosslinking agent, anhydrous ethanol (EtOH) or perfluorinated hexyl alc. (S104) as end capping agent. The mol. structure and relative mol. weight of aromatic polyurethane (PU) and FABPU were characterized by means of Fourier-transform IR (FTIR) and Gel permeation chromatog. (GPC). The results showed that the average mol. weight of FABPUs increased compared with that of PU. The characterization results by thermogravimetric (TG) and X-ray diffraction (XRD) showed that the crystallinity of FABPU-2 was enhanced 148.3%, as well as the thermal decomposition temperature was raised by 38°C. The yellowing resistance of FABPU and aromatic fluorine-free PU was investigated by the change of yellowness index (YI), chromatic aberration (ΔE). The results showed that compare with that of aromatic fluorine-free PU, YI of FABPU-2 decreased to 14.3 from 32.48, as well as ΔE reduced to 5.07 from 16.34. Moreover, the water contact angle of FABPU-2 increased to 141° from 89.3°. These indicated that the crosslinking of pentaerythitol and the introduction of fluorine obviously improved the hydrophobicity and yellowing resistance of aromatic PU.
Electric Literature of 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., 647-42-7.
