Continuous process for decarboxylating carboxylic acids

2A continuous process for decarboxylating carboxylic acids proceeds by I.) initially charging a carbonyl compound as a catalyst in a solvent at reaction temperature, to obtain a catalyst solution; II.) metering a carboxylic acid into the catalyst solution as an aqueous solution, aqueous suspension o...

Summary:2A continuous process for decarboxylating carboxylic acids proceeds by I.) initially charging a carbonyl compound as a catalyst in a solvent at reaction temperature, to obtain a catalyst solution; II.) metering a carboxylic acid into the catalyst solution as an aqueous solution, aqueous suspension or as a water-comprising solid, to obtain a reaction mixture; and III.) continuously removing a mixture of CO, solvent, water and a reaction product or mixture of reaction products from the reaction mixture as a vapor.
