Claims10
A process for oxidation of hydrocarbons comprising contacting said hydrocarbon with an oxidizing agent in the presence of a catalytically effective amount of a crystalline, titanium-containing molecular sieve for a time and at a temperature effective to oxidize said hydrocarbon, wherein the crystalline titanium-containing molecular sieve is a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) titanium oxide, and having, after calcination, the X-ray diffraction lines of Table II.
A process for epoxidation of an olefin comprising contacting said olefin with hydrogen peroxide in the presence of a catalytically effective amount of a crystalline, titanium-containing molecular sieve for a time and at a temperature effective to epoxidize said olefin, wherein the crystalline titanium-containing molecular sieve is a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) titanium oxide, and having, after calcination, the X-ray diffraction lines of Table II.
A process for oxidizing cyclohexane comprising contacting said cyclohexane with hydrogen peroxide in the presence of a catalytically effective amount of a crystalline, titanium-containing molecular sieve for a time and at a temperature effective to oxidize said cyclohexane, wherein the crystalline titanium-containing molecular sieve is a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) titanium oxide, and having, after calcination, the X-ray diffraction lines of Table II.
A catalytic oxidation process comprising contacting under oxidation conditions (1) a reactant which is catalytically oxidizable in the presence of hydrogen peroxide, (2) aqueous hydrogen peroxide and (3) a catalytically effective amount of an oxidation catalyst comprising a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) titanium oxide, and having, after calcination, the X-ray diffraction lines of Table II.
A process for the epoxidation of an olefin comprising contacting said olefin with hydrogen peroxide in the presence of a catalytically effective amount of a catalyst comprising a molecular sieve having a mole ratio greater than about 15 of (1) silicon oxide to (2) titanium oxide, and having, after calcination, the X-ray diffraction lines of Table II.
