BICYCLIC AMIDE ACETALS ARE PREPARED FROM ORGANIC NITRILES AND DIALKANOL AMINES AT BELOW ABOUT 140 C AND PRODUCT IS ISOLATED BY SOLVENT EXTRACTION

摘要

An improved process as described for preparing bicyclic amide acetals from an organic nitrile and a dialkanol amine, wherein the reaction temperature is maintained in the range of from room temperature to 140.degree.C. The resulting bicyclic amide acetal product is removed from the reaction mixture by extraction into a hydrocarbon or organic nitrile solvent prior to its purification. These acetals were found to be particularly suitable as chemical intermediates in the preparation of polyurethanes, epoxy resins and the like.
