The present invention provides a novel salt useful as an active species in an organic reaction and represented by the following chemical formula (1):
wherein n stands for an integer of from 1 to 8, Zn- represents an n-valent anion of an active hydrogen compound, a, b, c and d each stands for a positive integer, and Rs represent the same or different hydrocarbon groups. Also disclosed is a simple and efficient process for producing a poly(alkylene oxide) by polymerizing an alkylene oxide compound in the presence of the salt represented by the chemical formula (1).
本发明提供了一种新型盐,可作为有机反应中的活性物质,其化学式如下(1):
其中 n 代表 1 至 8 的整数,Zn- 代表活性氢化合物的 n 价阴离子,a、b、c 和 d 各代表一个正整数,Rs 代表相同或不同的烃基。本发明还公开了一种简单高效的聚环氧亚烷烃生产工艺,该工艺是在化学式(1)所代表的盐存在下,通过聚合环氧亚烷烃化合物来生产聚环氧亚烷烃。
