氯甲酸乙酯尾气综合利用的研究

Study of the Ethyl Chloroformate Exhaust Comprehensive Utilization

氯甲酸乙酯生产过程中,光气过量约5％～20％,使用氯甲酸乙酯和乙醇混合物吸收尾气,通过调节反应温度、氯甲酸乙酯与乙醇配比、反应时间,吸收尾气制得的氯甲酸乙酯含量在98％以上.

Ethyl chloroformate in the production process,phosgene is about 5％ to 20％,using ethyl chloroformate and ethanol mixture to absorb the exhaust gas,by adjusting the temperature of the reaction,ethyl chloroformate,with the ratio of ethanol,the reaction time,the absorption of the exhaust gas obtained the ethyl chloroformate content above 98％.
