Application

Potassium carbonate has been used in the preparation of disulfonated bis[4-(3-aminophenoxy)phenyl]sulfone, a disulfonated diamine monomer.It may be used in the following studies:As a reagent in the synthesis of polysubstituted iodobenzene derivatives. As a base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.As a base for the Suzuki coupling of aryl halides with aryl boronic acids.The Heck reaction of styrene and bromobenzene.

General description

Potassium carbonate is an inorganic base. It participates as a base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene. Addition of amino acids (glycine, sarcosine and proline) to K2CO3 (solvent) promotes the absorption of CO2.
