Abstract: A PROCESS FOR THE OXIDATION OF KETONES IN THE LIQUID PHASE WHICH COMPRISES SUBJECTING AN ASYMMETRICAL KETONE R-CO-R'', WHERE R IS A PARAFFINIC OR OLEFINC HYDROCARBON RADICAL CONTAINING AT LEAST 2 CARBON ATOMS, SUBSTITUTED OR NOT, AND R'' IS A SATURATED ALIPHATIC RADICAL CONTAINING NOT MORE THAN 2 CARBON ATOMS, TO OXIDATION IN THE PRESENCE OF MOLECULAR OXYGEN AT A PARTIAL PRESSURE OF 0.1 TO 50 ATMOSPHERES AND IN THE PRESENCE OF A MANGANESE SALT, THE MOLAR RATIO OF MANGANIC SALT TO KETONE BEING HIGHER THAN 0.1, AT A TEMPERATURE FROM 20 TO 130*C., WITH THE SELECTIVE FORMATION OF THE ACID R-COOH WHEREIN R IS AS DEFINED ABOVE.

Abstract: A PROCESS FOR THE PRODUCTION OF THE MANGANIC SALT OF AN ALIPHATIC CARBOXYLIC ACID, WHICH COMPRISES TREATING IN LIQUID PHASE BY AN OXYGEN CONTAINING GAS, A MANGANOUS COMPOUND FROM THE GROUP CONSISTING OF MANGANOUS SALT OF SAID CARBOXYLIC ACID, AMANGANOUS SALT OF A WEAKER THAN SAID CARBOXYLIC ACID, MANGANOUS OXIDE AND MANGANOUS HYDROXIDE, IN THE PRESENCE OF A KETONE HAVING THE FORMULA R-CO-R1, WHEREIN R IS AN ALIPHATIC OR AROMATIC RADICAL AND R1 IS AN ALIPHATIC RADICAL OR FORMS WITH R A CYCLOALKANE RADICAL, AND IN THE PRESENCE OF SAID CARBOXYLIC ACID OF WHICH SAID MANGANIC SALT IS A DERIVATIVE, AT A TEMPERATURE FROM 50 TO 130*C.
