摘　　要：氯化反应含有氯气的氯化氢尾气用水吸收得到副产盐酸Ⅰ,酰氯化反应含有二氧化硫的氯化氢尾气用水吸收得到副产盐酸Ⅱ,两股副产盐酸以一定比例混合,使其中的氯气和二氧化硫发生氧化还原反应,得到无色的盐酸,用于羧酸钠盐的酸化。这些综合应用方法达到了废物利用的目的。Exhaust from chlorination reaction containing chlorine was absorbed with water to obtain type I hydrochloric acid. Exhaust from chloroformylation reaction containing sulphur dioxide was absorbed with water to obtain type Ⅱ hydrochloric acid . Chlorine and sulphur dioxide can react oxidation-reduction reaction via mixing the two type hydrochloric acid, to obtain colourless hydrochloric acid. This hydrochloric acid was used to acidize sodium carboxylate. The comprehensive application method plays a good role in the utilization of waste.
