| 摘 要： | 本文讨论以工业KCI和NH4HCO3为原料、采用离子交换法（国产732钠型树脂）生产K2CO3的工艺。小试验的结果：以20％KCI溶液上柱，以分段交换率在50％以前为穿漏点、流速为0．033(ml/min.ml树脂）时，总交换率达83．3％，工作交换容量达2．24（毫摩尔钾／ml树脂）；当以饱和NH4HCO3溶液进行解脱、流速在0．033(ml/min.ml树脂）时，解脱率达91．8％，产品的含量为98．2％。

| Abstract: | In order to produce potassium carbonate, the method presented here uses a strongly acidic cation exchange resin,applying industrial potassium chlorate and ammonium hydrogen carbonate as raw materials. The exchange rate of the potassium chlorate can reach 83.3%. When ammonium hydrogen carbonate is used as washing agent,the washing rate can reach 91.8% ,and the potassium carbonate concentration of the product is 98. 2%. |
