PROCESS FOR THE THE PREPARATION OF A MIXTURE OF A CYCLOALKANO AND THE CORRESPONDING CYCLOALKANONE WHICH COMPRISES HEATING A SOLUTION OF A CYCLOALKYLHYDROPEROXIDE HAVING 5 TO 16 CARBON ATOMS IN THE RING, IN THE CORRESPONDING CYCLOALKANE, THE SOLUTION CONTAINING, AS CATALYST, A SOLUBLE DERIVATIVE OF VANADIUM, MOLYBDENUM OR RUTHENIUM HAVING A SOLUBILITY OF AT LEAST 0.1 GRAMS PER LITER IN THE CYCLOALKANE AT AMBIENT TEMPERATURE.
Claim 2
Dependent Claim
65 words
PROCESS FOR THE THE PREPARATION OF A MIXTURE OF A CYCLOALKANO AND THE CORRESPONDING CYCLOALKANONE WHICH COMPRISES HEATING A SOLUTION OF A CYCLOALKYLHYDROPEROXIDE HAVING 5 TO 16 CARBON ATOMS IN THE RING, IN THE CORRESPONDING CYCLOALKANE, THE SOLUTION CONTAINING, AS CATALYST, A SOLUBLE DERIVATIVE OF VANADIUM, MOLYBDENUM OR RUTHENIUM HAVING A SOLUBILITY OF AT LEAST 0.1 GRAMS PER LITER IN THE CYCLOALKANE AT AMBIENT TEMPERATURE.
Claim 3
Dependent Claim
50 words
Process for the preparation of a mixture of a cycloalkanol and the corresponding cycloalkanone which comprises heating a solution of a cycloalkylhydroperoxide having 5 to 16 carbon atoms in the ring in the corresponding cycloalkane, the solution containing, as catalyst, a naphthenate, octoate or acetylacetonate of vanadium, molybdenum or ruthenium.
Claim 4
Dependent Claim
50 words
Process for the preparation of a mixture of a cycloalkanol and the corresponding cycloalkanone which comprises heating a solution of a cycloalkylhydroperoxide having 5 to 16 carbon atoms in the ring in the corresponding cycloalkane, the solution containing, as catalyst, a naphthenate, octoate or acetylacetonate of vanadium, molybdenum or ruthenium.
Claim 5
Dependent Claim
