ester 是酯的意思了,并非碳酸酯,昏迷啊,居然在网站上搜到了这段话的英文翻译,连数据都基本一样

A flask equipped with an agitating blade, dropping funnel, thermometer, ester adapter and reflux condenser was charged with 42.0 g (0.10 mol) of an epoxy resin having formula (8) shown below and 168.0 g of toluene, after which water was azeotroped off at 130.degree. C. for 2 hours. To the flask cooled to 100.degree. C., 0.5 g of a catalyst (CAT-PL-50T by Shin-Etsu Chemical Co., Ltd.) was added dropwise. Immediately thereafter, a mixture of 36.3 g (0.05 mol) of an organopolysiloxane having formula (14) shown below and 145.2 g of toluene was added dropwise over about 30 minutes to the solution, which was then ripened at 100.degree. C. for 6 hours. Removal of the toluene yielded a yellow clear liquid having a viscosity .eta. of 5 Pa.multidot.s at 25 .degree.C., an epoxy equivalent of 400 and an organopolysiloxane content of 46.4 parts by weight. This is designated Compound A. |
