从七氟烷合成废液中回收六氟异丙基氯甲基醚

Recovery of Sevochlorane from the Waste Stream of Sevoflurane Synthesis

在七氟烷的合成过程中,其杂质F在粗品含有约5%,粗品精馏提纯后该物质被富集到精馏残余液中,本文通过其与无水三氯化铝、三聚甲醛进行反应,将其转化为六氟异丙基氯甲基醚,减少了环境污染,降低了成本。

In the synthesis process of sevoflurane,the impurity F took up about 5% in crude product.After distillation purification of the crude product it was concentrated in distillation residue.By reacting with anhydrous aluminium chloride and s-Trioxane,sevochlorane were recycled
