Descripción

Descripción general

Potassium sulfate is a water-soluble inorganic salt that is commonly used in fertilizers. It can be prepared by reacting phosphogypsum and potassium chloride. K₂SO₄ can form needle-like mullite particles on heating with aluminum sulfate and silicon dioxide. Its application to the soil has shown to minimize bronzing of rice plants.

Aplicación

Potassium sulfate may be used as a sulfonating agent in the preparation of 4′-dibenzo-18-crown-6-sulfonic acid via sulfonation of dibenzo-18-crown-6.
