    Abstract: Naphtha feed stocks are converted to high octane products in a long cycle semi-regenerative operation utilizing a catalyst comprising alumina in association with 0.15 to 0.75 weight percent platinum, 0.15 to 0.45 weight percent iridium and 0.3 to 2.0 weight percent chlorine, each based on total catalyst, the surface area of the platinum and iridium on the alumina being at least about 200 square meters per gram of platinum and iridium as determined by carbon monoxide chemisorption techniques. The catalyst should contain less than about two atoms of sulfur per atom of platinum and iridium and be substantially free of alkali and alkaline earth metal constituents.

    Abstract: A PROCESS FOR THE PREPARATION OF A FLUORINATION CATALYST WHEREIN CHROMIUM AND NICKEL SALTS OF ORGANIC ACIDS ARE TREATED AT AN ELEVATED TEMPERATURE UNDER VACUUM OR IN AN INERT ATMOSPHERE TO PRODUCE NON-STOICHIOMETRIC INORGANIC COMPOUNDS IN WHICH THE CHROMIUM HAS A VALENCE BETWEEN 2 AND 3 AND THE NICKEL HAS A VALENCE BETWEEN 0 AND 2, AND THE MIXTURE OF THE NON-STOICHIOMETRIC COMPOUNDS THEREBY OBTAINED IS SHAPED AND IS THEN CONTACTED WITH ANHYDROUS HYDROGEN FLUORIDE AT AN ELEVATED TEMPERATURE. THE CATALYSTS OF THE PRESENT INVENTION ARE USEFUL IN THE PREPARATION OF PERFLUORO COMPOUNDS BY REACTION OF PERHALOGENATED COMPOUNDS WITH HYDROGEN FLUORIDE.

    Abstract: AN IMPROVED PROCESS FOR PRODUCING CO-CRYSTALS OF TITANIUM TRICHLORIDE AND ALUMINUM TRICHLORIDE WITH A DESIRED COMPOSITION, PREFERABLY SUBSTANTIALLY THREE MOLES OT TITANIUM TRICHLORIDE AND ONE MOLE OF ALUMINUM TRICHLORIDE AND SUBSTANTIALLY FREE OF IMPURTIES IS DESCRIBED. SUCH CRYSTALS ARE OF VALUE AS AN ACTIVE CATALYST, PARTICULARLY, FOR EXAMPLE, FOR PREPARING POLYPROPYLENE. THE CO-CRYSTALS ARE PREPARED BY REACTING TITANIUM TETRACHLORIDE WITH ALUMINUM IN AN EXCESS OF TITANIUM TETRACHLORIDE. AFTER REACTION, EXCESS TITANIUM TETRACHLORIDE IS VAPORIZED BY HEATING THE CO-CRYSTALS. THE IMPROVED PROCESS PROVIDED HEREIN INVOLVES DRY BALL MILLING OF ALUMINUM TRICHLORIDE WITH ALUMINUM POWDER PRIOR TO REACTING WITH TITANIUM TETRACHLORIDE SO THAT A SELECTED EXCESS OF ALUMINUM TRICHLORIDE OVER THE DESIRED COMPOSITION IS PRESENT IN THE PRODUCT TO COMPENSATE FOR ALUMINUM TRICHLORIDE VOLATILIZED IN THE DRYING OPERATION. THIS SERVES THE MULTIPLE FUNCTIONS OF YIELDING CO-CRYSTALS OF CONTROLLED COMPOSITION, ACTIVATING THE ALUMINUM POWDER FOR COMPLETE REACTION, PROMOTING INITIATION OF REACTION BETWEEN ALUMINUM AND TITANIUM TETRACHLORIDE AND ENHANCING RATE OF REACTION TO OBVIATE ANY NEED FOR STIRRING OF THE REACTION MIXTURE.
