C1-Cu2＋-SO32-体系中制备氯化亚铜

Cuprous chloride preparation in the system of C1- -Cu2＋ -SO3 2-

本文主要进行了二价铜在溶液中用亚硫酸根将其还原成一价铜，并用氯离子作为沉淀剂制取氯化亚铜的研究。氯化亚铜生成过程中会产生H＋，反应体系pH对氯化亚铜产品收率影响最大，所以过程中可通过滴加碳酸钠来控制体系酸度，并根据还原反应发生的速度控制碳酸钠的滴加速度来中和体系中的生成的酸，保持体系pH在2．0～3．0，使氯化亚铜产率达到92％以上。

This paper mainly using sulfurous acid root of Cu2＋ in solution were carried out to restore it into Cul＋ , and chlorine ion as precipitant for making research of cuprous chloride. Cuprous chloride generated in the process can produce H＋, reaction system pH of cuprons chloride has the greatest effect in the yield, so the process can add sodium carbonate to control the system acidity, and according to the dropping speed of reduction reaction occurs the speed control of sodium carbonate to neutralize generated acid in the system, maintaining system pH at 2.0-3.0, production rate of cuprous chloride over 92%.
