Potassium carbonate sesquihydrate can be used as a sorbent for the removal of CO
2 from 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]
