摘　　要：本文通过分析研究氯醇化法生产环氧丙烷的反应机理及影响氯醇化反应的各种要素:工艺水温度对氯气溶解的影响、氯气与丙烯的配比对氯醇化反应影响从而得出控制优化氯醇化生产环氧丙烷的方法以及实际生产经验与理论实践的相结合。通过研究氯醇化反应生成环氧丙烷所需公用工程:循环水、盐水流量压力变化,氮气流量压力变化以及精馏压力变化时成品环氧丙烷中杂质氯甲烷含量的色谱变化趋势来判断公用工程变化时,对氯甲烷的影响及公用工程与氯甲烷含量关系。In this paper,through the analysis of the influence of various factors,influence of process water temperature chloroalcohol reaction of chlorine dissolved chlorine and the ratio of propylene chlorohydrination and the ratio of chlorine and propylene on the reaction effect and obtain optimal control of chlorohydrin production of propylene oxide and the combination of theory and practice of the practical experience of producing propylene oxide chloride aging method. Utilities required by the generation of epoxy propane chloroalcohol reaction： the change of circulating water,brine flow pressure,nitrogen flow pressure change and distillation pressure changes the impurity content of methyl chloride products in propylene oxide chromatography to determine the trend of public engineering changes,the relation of methyl chloride and methyl chloride content and utilities.
