摘要
为解决氯化亚砜产品纯度低、杂质含量高的问题,对氯化亚砜合成及精馏过程进行了技术改造。改造后,氯化亚砜质量分数≥99.0%,色号≤1~#。
In order to solve the problem of low purity and high impurity content of thionyl chloride products, technical modifications were carried out on synthesis process and on distillation process. Thus, thionyl chloride mass fraction increased to ≥99.0%, and color number reduced to≤1~#.
