阿里彩票骗局:BDO - 1, 4 Butanediol
Chemistry: Intermediates and SolventsSDS Link >
阿里彩票登陆平台 www.o1e1e.com.cn Butanediol intermediate is a versatile diol precursor to numerous derivatives such as esters, carbamates, polyesters and urethanes. It is used mainly as a co-monomer in classical diol-condensation reactions with terephthalic acid to produce polybutylene terephthalate (PBT), with diisocyanates to produce polyurethanes and with diacids to yield polyesters with biodegradability characteristics. BDO is also used as an intermediate to make polyurethane that is used in auto bumpers and dash boards.
Butanediol intermediate’s reactive sites are its hydroxyl groups, which undergo all the typical reactions of alcohols. In addition to the condensation reactions noted above, it can be converted to simple esters and halides, dehydrated to tetrahydrofuran (THF) and dehydrogenated to gamma-butyrolactone.
