  公开（公告）日：1988-11-17

  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.
