Abstract: A METHOD FOR PREPARING 2-PYRROLIDINONE BY CONTACTING 5-NITRO-3-PENTANONE WITH AN ACIDIC OXIDIZING AGENT THEREBY FORMING 4-NITROBUTYRIC ACID AND THEREAFTER HYDROGENATING THE 4-NITROBUTYRIC ACID IN AN ALCOHOLIC MEDIUM IN THE PRESENCE OF A MINOR AMOUNT OF A MINERAL ACID AND A HYDROGENATING CATALYST AT TEMPERATURES RANGING FROM ABOUT 20 TO 200*C. ANDROGEN PRESSURES OF FROM 1 TO 100 ATMOSPHERS. THE PRODUCT 2-PYRROLIDINONE CONTEMPLATED HEREIN IS USEFUL AS A SOLVENT FOR POLYMERS, INSECTICIDES AND PETROLEUM PROCESSING AND SEPARATIONS, AS A PLASTICIZER FOR ACRYLIC POLYMERS AND COPOLYMERS, AS A DECOLORIZING AGENT, AND AS A MONOMER FOR FORMING A POLYAMIDE.

Abstract: A METHOD FOR PREPARING A 4-NITROALKANOIC ACID 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)(-R7)-NO2

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

THE CONTEMPLATED 4-NITROALKANOIC ACIDS ARE USEFUL AS PLASICIZERS, BACTERIOCIDES, LBRICANT ADDITIVES, FUEL ADDITIVES, ANTI-RUST AGENTS AND AS PRECURSORS FOR THE PREPARATION OF 2-PYRROLIDINONE.
