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.
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:
It may be used:
- 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.
- In the Heck reaction of styrene and bromobenzene.
Features and Benefits
- Increased efficiency – Eliminate time and effort of loosening hardened powders
- Safety – Avoid risks of using tools of force to break up clumps
- Economy – Faster preparation and solvation increase productivity and reduce costs
- Assured quality – Excellent, expert-tested quality with no anti-caking agents
- Flexible volumes – Available from research amounts to scale-up quantities
