Abstract 1. A METHOD FOR PRODUCING A SELECTED DIMETHYLBENZENE FROM A MIXTURE OF ISOMERS OF SAID SELECTED DIMETHYLBENZENE CONTAINING ETHYLENEBENZENE WHEREIN THE RATIO OF DIMETHYLBENZENE ISOMERS IS OTHER THAN AN EQUILIBRIUM RATIO WHICH COMPRISES CONTACTING SAID DIMETHYLBENZENE MIXTURE AT A TEMPERATURE FROM ABOUT 700*F. TO ABOUT 950*F. IN THE VAPOR PHASE AT A FEED RATE OF ABOUT 1.0 TO 10.0 V/V/HOUR THE PRESENCE OF THE HYDROGEN AT A HYDROGENTO-OIL MOL RATIO OF ABOUT 6.0 TO ABOUT 10 TO 1 WITH A MOLYBDENUM OXIDE OF OFFRETITE HAVING THE FORMULA (KCA(AL3SI3O16).6H2O) CATALYST, SAID OFFRETITE HAVING BEEN TREATED WITH AMMONIUM SALT AND HEATED TO FORM THE HYDROGEN FORM FOLLOWED BY COOLING AND IMPREGNATION WITH AMMONIUM MOLYBDATE TO FORM ON DRYING SAID MOLYBDENUM OXIDE ON OFFRETITE CATALYST, TO FORM AN ISOMERIZED PRODUCT CONTAINING ETHYLBENZENE AND RECOVERING SAID SELECTED DIMETHYLBENZENE FROM SAID ISOMERIZED PRODUCT.
