With Green Freedom, they would pass the air over a solution of potassium carbonate added to the cooling liquid.
Coumarin has been synthesized in Perkinreaction of acetic anhydride and salicylaldehydecatalyzed by anhydrous potassium carbonate.
The original ammonia removal process by evaporation was replaced by air stripping at vacuum in the production of potassium carbonate with ion-exchange method.
Methods Chalcone derivatives were synthesized from benzaldehyde derivatives and acetophenone by using weak alkali potassium carbonate as based catalyst in water via phase - transfer catalysis.
The reaction of bis-imidazoline with 1,2-dibromoethane and potassium carbonate in acetonitrile provided monobromide salt with a yield of 78.
