Total Claims: 21
Claim 1
Independent Claim
174 words
In a process for producing a mixture containing decomposition products of an organic hydroperoxide wherein a hydrocarbon is oxidized in the presence of a molecular oxygen containing gas to provide a reation mixture containing the corresponding hydroperoxide of said hydrocarbon and said hydroperoxide is decomposed in the presence of starting hydrocarbon to provide a mixture containing reaction products of such decomposition reaction, including an alcohol and/or ketone products, the improvement which comprises conducting the oxidation reaction by contacting the hydrocarbon with a molecular oxygen containing gas at a temperature of from about 50° C. to about 250° C. in the presence of a catalytic amount of an admixture of chromium and ruthenium compounds which are soluble in said reaction mixture, and conducting the decomposition reaction by contacting a reaction mixture containing the hydroperoxide of the hydrocarbon starting material at a temperature of from about 25° C. to about 250° C. in the presence of a diluent with a catalytic amount of said catalyst admixture, optionally in the presence of a molecular oxygen containing gas.
