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.
本发明公开了一种生产高纯度季盐的工艺,包括将叔胺或膦与碳酸二酯反应生成相应的季碳酸盐,并进一步与酸混合进行脱羧反应。由此获得的季盐是有用的化合物,可广泛用作各种催化剂、电解质、添加剂、药物等。
