摘要
根据K＋、Na＋、Cl－■SO4（2－）－H2O对体系相图，在小试基础上，放大试验，用工业品氯化钾和工业品硫酸钠通过二步法制取硫酸钾。在实验室条件下，制取了符合ZBG21006－89标准的一等品硫酸钾及符合GB5462－85标准的二级品氯化钠。
It is enlarged on the basis of trival experiment.Potassium suplhate is made through the two processes with industrial product potassium Chloride and industrial product sodium sulphate We produced the first-class Potassium sulfate up to ZBG 21006-89 standard and the second-class sodium chloride up to GB 5462-85 standard at the laboratory.
