Abstract
A process for producing quaternary salts of high purity is disclosed, comprising reacting a tertiary amine or phosphine with a carbonic acid diester to form a corresponding quaternary carbonate and further mixing it with an acid to perform decarboxylation. The quaternary salts thus obtained are useful compounds which can be used in wide fields as various catalysts, electrolytes, additives, medicaments, etc.
