| Application: | Potassium carbonate has been used in the preparation of disulfonated bis[4-(3-aminophenoxy)phe 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 |
| 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. |
