摘　　要：在二氧化硫气相法合成氯化亚砜过程中,若氯气过量,则中间体一氯化硫增多,达到一定数量时,须将一氯化硫排出系统外暂存;当暂存的数量超过1t,就新增了一个重大危险源单元。试验研究了一氯化硫水解制备亚硫酸钠溶液的方法,不仅解决了氯化亚矾生产失衡的问题,还得到了用于离子膜法烧碱生产的原料。In the synthesis of sulfoxide chloride by sulfur dioxide gas phase process if chlorine gas is excessive,the intermediate sulfur monochloride will increase.When sulfur monochloride reaches a certain amount,it must be discharged from the system for temporary storage.When sulfur monochloride temporarily stored exceeds 1 t,a major hazard source unit was added.The method of producing sodium sulfite solution by hydrolysis of sulfur monochloride is experimentally studied.The method not only solves the problem of production imbalance of sulfoxide chloride,but also obtains raw materials used to ion-exchange membrane caustic soda production.
