提高甲烷磺酰氯收率的方法

Study on Increasing the Yield of Methanesulfonyl Chloride

报道了将甲烷磺酰氯合成装置的负压由 4kPa降至 10 0Pa ,压力控制阀设在合成装置尾气出口 ,合成反应的水全部循环使用 ,甲烷磺酸氯的收率提高 10 %以上。

By lowering the negative pressure of the synthesizer from 4 kPa into 100 Pa, setting the control pressure valve in the gas exit of the synthesizer, and recycling the synthesizer's water completely, the yield of methanesulfonyl chloride is raised over 10%
