Abstract: A METHOD FOR PREPARING A 2-PYRROLIDINONE BY CONTACTING A DINITROALCOHOL HAVING AT LEAST 5 CARBON ATOMS CORRESPONDING TO THE FORMULA:

R-C(-R1)(-NO2)-C(-R2)(-R3)-C(-R4)(-R5)-CH(-OH)-

C(-R6)(-NO2)-R7

WITH AN ACIDIC OXIDIZING AGENT AT A PH NOT EXCEEDING 4 THEREBY FORMING A 4-NITROALKANOIC ACID OF THE FORMULA:

R-C(-R1)(-NO2)-C(-R2)(-R3)-C(-R4)(-R5)-COOH

AND THEREAFTER HYDROGENATING THE 4-NITROALKANOIC ACID IN AN ALCOHOLIC MEDIUM IN THE PRESENCE OF A MINOR AMOUNT OF A MINERAL ACID AND A HYDROGENATION CATALYST PREFERABLY SELECTED FROM THE GROUPS OF PLATINUM METALS AT TEMPERATURES RANGING FROM ABOUT 20 TO 200*C. AND UNDER HYDROGEN PRESSURES OF FROM 1 TO 100 ATMOSPHERES. THE 2-PYRROLIDINONES CONTEMPLATED CORRESPOND TO THE FORMULA:

2-R,2-R1,3-R2,3-R3,4-R4,4-R5-PYRROLIDIN-5-ONE

AND ARE USEFUL AS SOLVENTS FOR POLYMERS, INSECTICIDES AND PETROLEUM PROCESSING AND SEPARATION; AS PLASTICIZERS FOR ACRYLIC POLYMERS AND COPOLYMERS; AND AS DECOLORIZING AGENTS.
