Abstract: A PROCESS FOR THE PREPARATION OF AN AROMATIC ACID SUCH AS TEREPHTHALIC ACID BY HYDROLYSIS OF TEREPHTHALONITRILE WHICH COMPRISES SUBJECTING TEREPHTHALONITRILE TO AQUEOUS HYDROLYSIS IN A CLOSED REACTOR AT 200*C. TO 300*C. UNTIL A HYDROLYSIS EQUILBRIUM IS OBTAINED, VENTING THE CLOSED SYSTEM TO REMOVE MORE THAN 50% OF A VAILABLE, AMMONIA, ADJUSTING THE VENTER SYSTEM TO A MOLALITY OF TEREPHTHALATE FROM 1.5 TO 2.5, SATURATING THE SYSTEM WITH CARBON DIOXIDE, AND ISOLATING THE PRECITATED TERPHTHALIC ACID BY SEPARATION UNDER A PRESSURE OF ABOUT 50 TO ABOUT 900 P.S.I.G.

Abstract: A PROCESS FOR PRODUCING ELECTRODE GRADE COKE FROM HIGH SULFUR AND METAL CONTAINING HYDROCARBON RESIDS COMPRISING THE STEPS OF (1) HEATING THE RESID AT 325-375*C. IN THE PRESENCE OF FINELY DIVIDED SODIUM AND UNDER NITROGEN OR HYDROGEN PRESSURE OF ABOUT 1500 P.S.I.G. FOR 1-3 HOURS, (2) WASHING THE SODIUM TREATED MATERIAL WITH WATER AND CO2 AT ELEVATED TEMPERATURE, (3) DEASPHALTING THE WASHED MATERIAL BY AN ALIPHATIC HYDROCARBON EXTRACTION TO YIELD A PERTOLEUM FRACTION LOW IN SULFUR AND METALS, AND (4) COKING SAID PETROLEUM FRACTION TO OBTAIN AN ELECTRODE GRADE COKE.

Abstract: NOVEL POLYOLEFIN OILS OF MONOMERS OF THE FORMULA
CH2=C(-R)-R1
WHEREIN R IS -CH3 AND -C2H5 AND R1 IS AN ALKYL GROUP OF FROM 1 TO 10 CARBON ATOMS, HAVE EXCEPTIONALLY HIGH VISCOSITY INDICES AND HIGH COEFICIENTS OF TRACTION AND CONSISTS ESSENTIALLY OF UNISOMERIZED, TRUE OLIGOMER, SUCH AS TRUE POLYISOBUTYLENE OLIGOMERS (E.G. C16H32, C20H40, C24H48 . . . C48H96). THE NOVEL OILS ARE USEFUL AS ELECTRICAL OILS, AS CHEMICAL INTERMEDIATES OR AS TRACTANTS (I.E. AS TRACTION FLUIDS OR AS COMPONENTS OF TRACTION FLUIDS). THE HYDROGENATED OILS ARE NOVEL AND ESPECIALLY USEFUL AS TRACTANTS, PARTICULARLY WHEN HYDROGENATED TO A BROMINE NUMBER LESS THAN 10 (MORE PREFERABLY, LESS THAN 5). THE UNIQUE CHARACTER OF THESE NOVEL OILS, WHETER OLEFINE AND/ OR PARAFIIN, CAN BE PROVED BY A COMBINATION OF GAS CHROMATOGRAPHY AND NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY (NMR). THESE OLEFINS, AND THE PARAFFINS PRODUCED BY HYDROGENATION THEREOF ARE CHARACTERIZED BY "CROWDED" AND STERICALLY HINDERED GEMINAL METHYL AND ISOLATED METHYLENE GROUPS. THE INDIVIDUAL SPECIES IN THE RANGE OF C16 TO C48 CAN BE SEPARATED FROM THE WHOLE OIL BY VAPOR PHASE CHROMATOGRAPHY. ONE SUCH NOVEL POLYOLEFIN OIL HAVING AN ASTM VISCOSITY INDEX GREATER THAN 85, CONSISTS ESSENTIALLY OF MONOOLEFINS OF CARBON NUMBERS, C24, C28, C32, C36 AND C40 AND HAVING REPEATING ISOBUTYLENE STRUCTURES.-

Abstract: PROCESS OF DEHYDROCYCLIZING C6-C10 PARAFFINS USING A SODIUM ZEOLITE X OR SODIUM ZEOLITE Y, WHICH ZEOLITE HAS BEEN ION EXCHARGED WITH FROM 0.10 TO 1.2 WEIGHT PERCENT PLATINUM, THE CATALYST CALCINED AND THE PLATINUM THEN REDUCED WITH HYDROGEN TO THE FREE METAL. IN AN ESPECIALLY PREFERRED ASPECT OF THE INVENTION, THE CATALYST IS GIVEN A FINAL ION EXCHANGE WITH A SODIUM SALT SUCH AS SODIUM BICARBONATE. THE DEHYDROCYCLIZATION REACTION IS CARRIED OUT AT FROM 500-560*C. AND PREFERABLY FROM 510 TO 555*C. USING A PARTIAL PRESSURE OF HYDROGEN OF FROM 10 TO 300 P.S.I.G. AND PREFERABLY 50 TO 200 P.S.I.G. TO FORM BENZENE AND ALKYLBENZENES.

Abstract: A MULTISTEP PROCESS IS DISCLOSED WHEREIN 5-O-TOLYLPENTENE-2 IS CONVERTED TO 1,5-DIMETHYLTETRALIN IN THE PRESENCE OF A SOLID ACIDIC CATALYST AT 200-450*C. AND PREFERABLY ALSO RECYCLED HYDROGEN, VAPORS FROM THIS CONVERSION ARE REACTED BY CONTACT AT 300-500*C. IN A HYDROGEN ATOMSPHERE WITH A SOLID DEHYDROGENATION CATALYST, PREFERABLY PLATINUM ON NON-ACIDIC ALUMINA, TO FORM 1,5-DIMETHYLNAPHTHALENE AND HYDROGEN, VAPORS FROM THE DEHYDROGENATION REACTION ARE CONTACTED AT 275-500*C. WITH A SOLID ACIDIC ISOMERIZATION CATALYST TO FORM 2,6-DIMETHYLNAPHTHALENE IN ADMIXTURE WITH MAINLY 1,6-DIMETHYLNAPTHALENE AND A SMALL PROPORTION OF THE 1,5-ISOMER, 2,6-DIMETHYLNAPHTHALENE 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.

AND PREFERABLE 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 1,6- AND 1,8-DIMETHYLNAPHTHALINES AND HYDROGEN, VAPORS FROM THE DEHYDROGENATION REACTION ARE CONTACTED AT 275500*C. WITH A SOLID ACIDIC ISOMERIZATION CATALYST TO FORM 2,6- AND 2,7 - DIMETHYLNAPHTHALENES IN ADMIXTURE WITH OTHER ISOMERS, THE 2,6- AND 2,7-DIMETHYLNAPHTHALENES ARE 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 CATALYST IN EITHER THE FIRST STEP OR THE ISOMERIZAION STEP, AND ALSO SUBSEQUENT TO THE DEHYDROGENATION STEP BY INDIVIDUALLY RECOVERING THE 1,6- AND 1,8-DIMETHYLNAPHTHALENE ISOMERS AND SEPARATELY ISOMERIZING EACH ISOMER TO FORM THE 2,6AND 2,7-ISOMERS RESPECTIVELY.
