Abstract: A novel method for producing methyl isobutyl ketone from acetone and hydrogen in one stage with improved conversion and selectivity by contacting acetone in liquid phase with hydrogen in the presence of a catalyst of (a) palladium and synthetic zeolite, or (b) palladium and alumina together with or without thorium oxide, zirconium oxide and/or chromium oxide, at a temperature of 100* to 250* C. and under a partial pressure of hydrogen of 0.1 to 10 kg per square centimeter.

Abstract: HIGH YIELD OF A-PYRROLIDONE ARE OBTAINED BY REACTING SUCCINONITRILE WITH HYDROGEN UNDER PRESSURE IN THE PRESENCE OF A HYDROGENATING CATALYST AT A TEMPERATURE OF 80* TO 200*C. IN A NITROGEN-CONTAINING BASIC ORGANIC SOLVENT FOR A REACTION PERIOD SHORTER THAN 3.7 MINUTES AND THEN CONTACTING THE THUS OBTAINED REACTION MIXTURE WITH WATER OR AQUEOUS AMMONIA SOLUTION AT A TEMPERATURE OF 200* TO 300*C. ALPHA-PYRROLIDONE IS USEFUL AS AN IMPORTANT RAW MATERIAL OF 4-NYLON AND AS A RAW MATERIAL FOR THE PRODUCTION OF N-METHYL PYRROLIDONE AND N-VINYL PYRROLIDONE, BOTH USEFUL AS A HIGH BOILING SOLVENT, OR AS A FIBER RAW MATERIAL.
