POTASSIUM CARBONATE, ANHYDROUS, FREE-FL

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:•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.
