Organic Structure

 

Production and Reactions

According to the Leblanc method, potassium chloride can be obtained from the sulfuric acid reaction.

2 KCl H2SO4? 2 HCl K2SO4

According to the Hargreaves method, sulfur dioxide, oxygen, water and potassium chloride are used as the starting material. SO2 can be obtained by evaporation of sulfuric acid and combustion of sulfur.

Potassium sulphate was obtained from alunite with high yield and production started to become widespread.
