Abstract: 1 PROCESS IS DISCLOSED FOR THE CONVERSION OF AN ACETALDIMINE AND ACRYLONITRILE IN A MOLAR RATIO OF AT LEAST 0.8 TO 1, RESPECTIVELY, AND AT A TEMPERATURE OF 70*C. TO 130*C. TO THE CORRESPONDING Y-CYANOBUTYRALDIMINE, THE UNCONVERTED REACTANTS BEING RECOVERED FROM THE REACTION MIXTURE AND RE-CYCLED. THE RESULTING Y-CYANOBUTYRALDIMINE PRODUCT CAN THEN BE HYDROLIZED TO THE CORRESPONDING Y-CYANOBUTYRALDEHYDE.
