摘要
对阴离子交换树脂生产中，含有二甲胺的胺化母液进行了处理，从中回收了甲缩醛，并把母液中的二甲胺转变成二甲胺盐酸盐，采用间接胺此法制得弱碱性阴离子交换树脂，既减少了环境污染，又降低了树脂的生产成本。
Aminating mother liquor containing dimethylamine in the production of anion resin is treated,methylal is recovered from it and dlmethylaminein the mother liquor is translated into dimethylamine hydrochloride.Faintlyalkaline anion resin is made from by the indirect amination.Not only environment pollution is decrised,but also production costs of the resin are reduced.
