Abstract: A METHOD FOR PREPARING OMEGA-NITROESTERS BY THERMALLY CLEAVING AND REACTING A CYCLIC ALPHA-NITROKETONE WITH AN ALCOHOL IN A NON-AQUEOUS ENVIRONMENT AT A TEMPERATURE OF FROM ABOUT 50 TO ABOUT 200*C. THE ESTERS SO PREPARED ARE USEFUL AS LUBRICANT AND FUEL ADDITIVES AND AS INTERMEDIATES FOR THE PRODUCTION OF AMINO ACIDS.

Abstract: 1. A METHOD FOR THE PREPARATION OF ESTERS WHICH COMPRISES CATALYTICALLY ELAVING AND REACTING AN ALPHA-BITROKETONE WHEREIN SAID ALPHA-NITROKETONE CORRESPONDS TO THE FORMULA:

R-CO-C(-R1)(-R2)-NO2

WHERE R IS AN ALKYL GROUP OF 1 TO 20 CARBON ATOMS OR AN ARYL GROUP OF FROM 6 TO 20 CARBON ATOMS, AND WHERE R1 AND R2 AR HYDROGEN, ALKYL GROUPS OF FROM 1 TO 20 CARBON ATOMS OR ALKYL GROUPS OF FROM 6 TO 20 CARBON ATOMS WITH AN ALCOHOL AT A TEMPERATURE OF FROM ABOUT 20*C, TO 120*C. IN A NON-AQUEOUS ENVIROMENT WITH A SUBSTANTIALLY INSOLUBLE CATALYST SELECTED FROM THE GROUP CONSISTING OF CARBONATES, FLUORIDES AND SALTS OF WEAKLY ACID ION EXCHANGE RESINS OF THE METALS SODIUM, POTASSIUM AND CALCIUM.

Abstract: 1. A METHOD FOR THE PREPARATION OF OMEGA-NITROESTERS WHICH COMPRISES CATALYTICALLY CLEAVING AND REACTING A CYCLIC ALPHA-NITROKETONE CORRESPONDING TO THE FORMULA:

O2N-CH
WHERE R IS A POLYMETHYLENE RADICAL OF FROM 1 TO 2 CARBONS OR A SUBSTITUTED POLYMETHYLENE RADICAL OF 2 T 22 CARBONS CONTAINING ONE OR MORE SUBSTITUTENTS SELECTED FROM THE GROUP CONSISTING OF ALKYL AND ARYL, WITH AN ALCOHOL AT A TEMPERATURE OF FROM ABOUT 20*C. TO 120*C. IN A NON-AQUEOUS ENVIROMENT IN THE PRESENCE OF A SUBSTANTIALLY INSOLUBLE CATALYST SELECTED FROM THE GROUP CONSISTING OF CARBONATES, FLUORIDES, AND SALTS OF WEAKLY ACIDIC ION EXCHANGE RESINS OF THE METALS SODIUM, POTASSIUM, CALCIUM AND BARIUM.
