Abstract: Porous cellulosic stock can be coated with a thermoset polymer while being impregnated with a wax by this invention. A dispersion of solid particles of the precursor of a thermoset polymer in molten wax is applied to cellulosic stock at a temperature below the conversion temperature of the precursor. This treated cellulosic stock is then heated to a temperature above the conversion temperature of the precursor and subjected to pressure. The resulting laminated product is polymer coatedwax impregnated cellulosic stock. The solid precursor used must be substantially insoluble in the molten wax at a temperature below the conversion temperature of the precursor and must be convertible below a temperature which would degrade the stock. This product has utility as a packaging material comprising a high water vapor barrier coupled with a tough, scuff-resistant, non-blocking surface.

Abstract: A useful fuel for an internal combustion engine comprises a hydrocarbon base stock of gasoline boiling range, a methylsubstituted phenol and an ether containing a branched alkyl group and boiling below 460*F., said phenol and said ether each being present in amount (e.g., 0.1-15 wt. %) sufficient to increase the Research octane number (RON). The invention also includes a gasoline blending system. For example, preferred compositions can be made by blending 89 RON gasoline containing 5 vol. % p-cresol with 97 RON gasoline containing 5% methyl methoxy propane. Beneficial synergism is noted in such blends for RON blending values.

Abstract: COMPOUNDS CONTAINING HYDROGEN BONDED TO CARBON ARE CHLORINATED IN VAPOR PHASE WHEN INTRODUCED AT AN INTERMEDIATE LEVEL INTO A REACTOR MAINTAINED AT A TEMPEATURE IN THE RANGE OF 315-500*C. AND CONTAINING A BED OF FERROUS CHLORIDE WHICH BY INTERACTION WITH HCL AND OXYGEN IS USED TO PRODUCE FERRIC CHLORIDE VAPOR WHICH IS CONTACTED WITH THE C-H CONTAINING COMPOUND TO PRODUCE HCL, A C-CL GROUP, AND SOLID FECL2 WHICH FALLS TO THE BED. WHEN THE BED OF FERROUS CHLORIDE GRADUALLY CONVERTS TO OXYGENATED IRON COMPOUND, THE BED CAN BE PERIODICALLY REGENERATED BY INCREASING THE PROPORTION OF HCL:O2 AND CONTINUING TO OPERATE AT THE HIGH HCL:O2 MOLAR PROPORTION UNTIL SUBSTANTIALLY ALL OF THE OXYGENATED IRON COMPOUND HAS BEEN CONVERTED TO IRON CHLORIDE.

Abstract: A MULTISTEP PROCESS IS DISCLOSED WHEREIN 5-P-TOLYLPENTENE-2 IS CONVERTED TO 1,7-DIMETHYLTETRALIN IN THE PRESENCE OF A SOLID ACIDIC CARALYST AT 200-450*C. AND PREFERABLY ALSO RECYCLED HYDROGEN, VAPORS FROM THIS CONVERSION ARE REACTED BY CONTACT AT 300-500*C. IN A HYDROGEN ATMOSPHERE WITH A SOLID DEHYDROGENATION CATALYST, PREFERABLY PLATINUM ON NON-ACIDIC ALUMINA, TO FORM 1,7-DIMETHYLNAPHTHALENE AND HYDROGEN, VAPORS FROM THE DEHYDROGENATION REACTION ARE CONTACTED WITH 275-500*C. WITH A SOLID ACIDIC ISOMERIZATION CATALYST TO FORM 2,7-DIMETHYLNAPHTHALENE IN ADMIXTURE WITH 1,7-DIMETHYLNAPHTHALENE, 2,7DIMETHYLNAPHTHALENE IS RECOVERED FROM THE ISOMERIZATION PRODUCT, E.G. BY CRYSTALLIZATION, AND PART OF THE GENERATED HYDROGEN IS RECYCLED IN THE SYSTEM. THE PROCESS CAN BE VARIED IN SEVERAL WAYS, INCLUDING THE UTILIZATION OF A LIQUID ACIDIC CATALYST IN EITHER THE FIRST STEP OR THE ISOMERIZATION STEP.
