Synonym: Potassium hydrogen carbonate
Linear Formula: KHCO3
Molecular Weight: 100.12
General description
Potassium bicarbonate is a commercially available nontoxic base frequently used as a reagent as well as a pH regulator in research and industrial applications.
Application
Potassium bicarbonate can be used as:
- A catalyst to synthesize dimethyl carbonate and propylene glycol from propylene oxide, supercritical carbon dioxide, and methanol. In this process, KHCO3 also acts as a drying agent.
- A dopant in the epoxidation of propene in the presence of silica-supported vanadium oxide as a catalyst.
- A carboxyl source to synthesize Z-5-alkylidene-2-oxazolidinones via Ag2CO3 catalyzed carboxylative cyclization of propargylic amines.
