PREPARATION PROCESS OF POTASSIUM SULFATE AND ZINC CHLORIDE OUT OF ZINC SULFATE AND POTASSIUM CHLORIDE

摘要

The invention provides a process for the preparation of potassium sulfate and zinc chloride in an economic way with high purity, which involves dissolving zinc sulfate and potassium chloride in water, concentrating, and adding a lower alcohol to the mixture to cause metathesis.  To this end, zinc sulfate and potassium chloride are dissolved in water and are concentrated, by heating, to a paste phase.  To the paste phase mixture is added a lower alcohol, and consequently a metathesis reaction occurs.
