Abstract
K2SO4 is produced by reacting KCl with H2SO4 using 2.0 to 2.2 mols of KCl per mol of H2SO4 with stirring at from room temperature to 100 DEG C, and the resulting KHSO4 is reacted e.g. in a muffle furnace with unreacted KCl at 300 DEG to 400 DEG C. By this two- step process, overall reaction can be carried out at lower temperature and in shorter time, and long term continuous operation is possible.
