Opis

Opis ogólny

Potassium bicarbonate is a commercially available nontoxic base frequently used as a reagent as well as a pH regulator in research and industrial applications.

Zastosowanie

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.
