Title:
イミドのアルキル化法
Document Type and Number:
Japanese Patent JP4208978
Kind Code:
B2
Abstract:
A procedure is described for the alkylation of imides that is characterised by the fact that 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.
