氯化钾硫酸钠转化法制取硫酸钾的研究

Preparation of Potassium Sulfate by Treating Potassium Chloride with Sodium Sulfate

通过时Ｋ＋、Ｎａ＋Ｃｌ－、ＳＯ－Ｈ２Ｏ系统相图的分析与工艺计算，制定用分步法由硫酸钠转化氯分钾制取硫酸钾工艺流程。在实验室条件下制得符合肥料级的硫酸钾产品，并回收副产物氯化钠。过程中无废物排放。

The process for preparing potassium sulfate by treating potassium chloride with Sodium Sulfate is developed by an analysid of K+.Na+ Cl-.SO_4￣2-H_2O phase graph and process calculation.Under laboratory conditions fertilizer grade potassium sulfate is prepared and sodium chloride by-product is recovered.There is no waste emanating in the process.
