摘要
开展了以ＫＣＩ、（ＮＨ＿４）＿２ＳＯ＿４为原料制备Ｋ＿２ＳＯ＿４的研究工作。确定了循环比、洗涤条件与反应时间。Ｋ＿２总转化率达７５％，产品收率约９７％；产品中Ｃｌ含量为０．５％～１．５％。
DeveIopment of process on potassium sulphate by circulating is introduced in this paper,Reasonable process conditions are elected. As the resuIts showed, that K_2O conversion rate is about75%,yield of K_2SO_4 about 97%,Cl content 0.5%～1.5%。
