偏氯乙烯生产过程中质量和消耗的控制

The control of product quality and consumption in the production of vinylidene chloride

阐述了偏氯乙烯合成过程中氯化、皂化、精馏等工序的生产要点 ,通过严格的工艺控制 ,使偏氯乙烯的纯度稳定在 99%以上 (氯乙烯含量小于 0 .5 % ) ,每生产 1t偏氯乙烯消耗氯乙烯单体为

Production factors of chlorination,saponification and distillation in the synthesis of vinylidene chloride are discussed.By strictly controlling process,the purity of vinylidene chloride can stabilize above 99% with the content of vinyl chloride less than 0.5% and the consumption of vinyl chloride is 780 kg per ton vinylidene chloride.
