Abstract:The silylation reaction of polytetramethylene glycol (PTMG) with trimethylchlorosilane (TMS) in DMSO was studied as the first step of the synthesis of new fluorinated polyether glycol. The extent of silylation was measured by 1 H-NMR, and the silylation product was characterized with FTIR, 1 H-NMR. The effects of the experimental conditions, i.e., reaction time and temperature, silylation reagent concentration (TMS/OH molar ratio) were investigated. The increase in reaction temperature and reaction time favore… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
