Procedure for alkylation of imides

摘要

A process for the alkylation of imides wherein the imides are reacted with a dialkyl carbonate, in the liquid state, at a temperature of between 100 DEG C. and 250 DEG C. and at a pressure of between 0 and 60 atmospheres in the presence of a basic catalyst. The dialkyl carbonate reagents are not very toxic and are thermally stable and their use as alkylation agents makes it possible to produce waste products with a negligible saline content.
