ABSTRACT:
This patent describes the catalytic promotion of the reaction of oxirane-containing compounds with carboxylic acid compounds at high, ambient, and low temperature. Specifically, this patent describes the method of reacting oxirane-containing compounds with carboxyl-containing compounds, preferably at temperatures at or around ambient, in the presence of active chromium III tricarboxylate salts which have unoccupied coordination sites. More specifically this patent describes the preparation of catalytically active chromium III-tricarboxylates from normally catalytically inactive chromium III tri-carboxylate hydrates. These compounds are powerful catalysts for the reactions of oxirane compounds with both organic carboxylic acids and cyclic primary imides.
