Potassium peroxo-mono:sulphate triple salt mfr. without cold crystallisation

The potassium peroxomonosulphate triple salt 2KHSO5 . KHSO4 . K2SO4 is mfd. by adding a soln. contg. 55-70 wt.% H2SO5 and 15-30 wt.% H2SO4 into a working soln. contg. 28-38 wt.% KHSO5 and 18-28 wt.% KHSO4 and 0-3 wt.% K2SO4. To this mixture, H2SO4 and KOH is added so that a mole ratio of H2SO5 to ad...

Summary:The potassium peroxomonosulphate triple salt 2KHSO5 . KHSO4 . K2SO4 is mfd. by adding a soln. contg. 55-70 wt.% H2SO5 and 15-30 wt.% H2SO4 into a working soln. contg. 28-38 wt.% KHSO5 and 18-28 wt.% KHSO4 and 0-3 wt.% K2SO4. To this mixture, H2SO4 and KOH is added so that a mole ratio of H2SO5 to added H2SO4 to KOH of 3-1 to 3-5 to 8 results. Water vapour evolves and the triple salt separates from the suspension formed without pre-cooling.
