Application

Potassium carbonate sesquihydrate can be used as a sorbent for the removal of CO₂from flue gas in precombustion process.[1] It may be employed as a base in the cross-coupling of benzene boronic acid with benzoyl chloride in the presence of deposited Pd catalysts to give benzophenone.[2]

It may also be used as one of the reaction components in the preparation of:

1,2,3-triethylimidazolium[3]
1,2,3-triethyl-4-methylimidazolium[3]
2-ethyl-1,3,4-trimethylimidazolium[4]

General description

Crystals of potassium carbonate sesquihydrate belong to the monoclinic crystal system and space group C2/c.[1]
