以氯化亚砜为氯化剂氯化反应尾气的综合利用

将氯化亚砜氯化反应中产生的含有大量SO2的尾气与计算量的氯气混合通入装有三氯化磷的反应釜中,控制合适的反应条件可以回收得到满足要求的氯化亚砜返回氯化工序循环使用,同时副产含量为98.5%的三氯氧磷产品。尾气与氯气的适宜配比为1.42∶1,反应温度为55℃±3℃,回收氯化亚砜后的二次尾气中含有97.5%以上的HCl气体,吸收后得到合格的副产盐酸。

Chlorination Exhaust Comprehensive Utilization of Chlorinated Sulfone

Will chlorinated sulfone follows chlorination generated in contains a large number of SO2 exhaust and calculation of chlorine mixes with access to the reactor with PCl3,control appropriate reaction conditions can get the required chlorinated sulfone follows returns chlorinated process recycling,at the same time,pay in the content of 98.5%POCl3 products. Exhaust and chlorine suitable ratio for 1.42∶1,reaction temperature is 55 ℃+ 3 ℃, by recycling chlorinated sulfone follows after the second exhaust containing 97.5% above HCl in gas,after being absorbed get qualified pay production hydrochloric acid.
