摘要
通过硅氢加成反应合成了三甲基硅氧羰丙基-甲基二氯硅烷和乙氧羰丙基-甲基二氯硅烷,再分别与三氟丙基-甲基二氯硅烷和三甲基氯硅烷三元共水解,经酸催化平衡得到一定分子质量的酯基氟硅油.由2种酯基氟硅油在一定条件下水解得到了羧基改性氟硅油.
Trimethylsiloxyoxopropyl-methyldichlorosilane and ethoxyoxopropyl-methyldichlorosilane were synthesized by Hydrosilylation, and were triply co-hydrolyzed, resp,, with trifluoropropyl-methyldichlorosilane and trimethylchlorosilane followed by acid-catalyzed equilibrium to give ester- and fluorine-contg, silicone oils having definite mol. wt. These 2 ester- and fluorine-contg, silicone oils were hydrolyzed under definite conditions to yield carboxyl-modified fluorine-contg, silicone oils.
