Claim 1
Independent Claim
143 words
IN A METHOD FOR THE OXIDATION OF AN OLEFIN HYDROCARBON OF 2 TO 18 CARBON ATOMS, THE STEPS COMPRISING CONTACTING SAID OLEFIN AT A TEMPERATURE OF ABOUT 50 TO 300*C. AND A PRESSURE SUFFICIENT TO MAINTAIN THE LIQUID PHASE AND IN THE PRESENCE OF MOLECULAR OXYGEN WITH A CALCINED SOLID OXIDATION CATALYST CONTAINING A MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE SILICATES AND ALUMINATES OF PROMOTING METALS HAVING AN ATOMIC NUMBER OF 24 TO 28, SAID CATALYST BEING OBTAINED BY CALCINATION OF A CATALYST PRECURSOR PREPARED BY THE COPRECIPITATION OF A CATALYTIC AMOUNT OF SAID PROMOTING METAL WITH A SOLID INORGANIC BASE, IN HYDRATED FROM, SELECTED FROM THE GROUP CONSISTING OF ALUMINA AND SILICA, SAID CALCINATION BEING AT A TEMPERATURE OF ABOUT 250 TO 700*C. FOR A TIME SUFFICIENT TO REMOVE THE PREDOMINANT AMOUNT, BUT NOT ALL, OF THE WATER OF HYDRATION.

IN A METHOD FOR THE OXIDATION OF ALLYL ACETATE TO GLYCERINE ESTERS, THE STEPS COMPRISING CONTACTING SAID ALLYL ACETATE AT A TEMPERATURE OF ABOUT 50 TO 300*C. AND A PRESSURE SUFFICIENT TO MAINTAIN THE LIQUID PHASE AND IN THE PRESENCE OF MOLECULAR OXYG EN WITH A CALCINED SOLID OXIDATION CATALYST CONTAINING A MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE SILICATES AND ALUMINATES OF PROMOTING METALS HAVING AN ATOMIC NUMBER OF 24 TO 28, SAID CATALYST BEING OBTAINED BY CALCINATION OF A CATALYST PRECURSOR PREPARED BY THE COPRECIPITATION OF A CATALYTIC AMOUNT OF SAID PROMOTING METAL WITH A SOLID INORGANIC BASE, IN HYDRATED FORM, SELECTED FROM THE GROUP CONSISTING OF ALUMINA AND SILICA, SAID CALCINATION BEING AT A TEMPERATURE OF ABOUT 250 TO 700*C.
