Abstract: NOVEL INDIVIDUAL HYDROCARBON SPECIES, USEFUL AS CHEMICAL INTERMEDIATES OR AS COMPONENTS OF TRACTION FLUIDS, CAN BE OBTAINED FROM THE MIXTURE OF HYDROCARBON FLUIDS OBTAINED FROM THERMALLY CRACKING HIGH MOLECULAR WEIGHT POLYISOBUTYLENE. OTHER NOVEL HYDROCARBONS ARE OBTAINED BY HYDROGENATION OF THE NOVEL OLEFINS. THE UNIQUE CHARACTER OF THESE OLEFIN AND PARAFFIN HYDROCARBONS CAN BE PROVED BY A COMBINATION OF GAS CHROMATOGRAPHY AND NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY (NMR). THIS DISCOVERY INVOLVED THE PREPARATION AND CHARACTERIZATION OF A HOMOLOGOUS SERIES, C11 TO C40, OF SIXTEEN BRANCHED HYDROCARBON SPECIES CONSISTING OF REPEATING ISOBUTYLENE STRUCTURES AND PROVES THAT THESE HYDROCARBONS ARE UNIQUE SPECIES WHICH ARE CHARACTERIZED BY "CROWDED" AND STERICALLY HINDERED GEMINAL METHYL AND ISOLATED METHYLENE GROUPS.

Abstract: A MULTISTEP PROCESS IS DISCLOSED WHEREIN 5-PHENYLHEXENE-2 IS CONVERTED TO 1,4-DIMETHYLETRALIN IN THE PRESENCE OF A SOLID ACIDIC CATALYST AT 200-450*C. AND PREFERABLY ALSO RECYCLED HYDROGEN, VAPORS FROM THIS CONVERSION ARE REACTED BY CONTRAST AT 300-500*C. IN A HYDROGEN ATMOSPHERE WITH A SOLID DEHYDROGENATION CARALYST, PREFERABLY PLATINUM ON NON-ACIDIC ALUMINA, TO FORM 1,4-DIMETHYLNAPHTHALENE AND HYDROGEN, VAPORS FROM THE DEHYDROGENATION REACTION ARE CONTACTED AT 275-500*C. WITH A SOLID ACIDIC ISOMERIZAION CARALYST TO FORM 2,3-DIMETHYLNAPHTHALENE IN ADMIXTURE WITH 1,3-DIMETHYLNAPHTHALENE, 2,3-DIMETHYLNAPHTHALENE IS RECOVERED FROM THE ISOMERIZATION PRODUCT, E.G. BY CRYSTALLIZAION, 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.

Abstract: A PROCESS FOR MAKING MONOAMMONIUM TEREPHTHALATE OF HIGH PURITY WHICH COMPRISES HEATING A SOLUTION OF DIAMMONIUM TERPHTHALATE TO A TEMPERATURE BETWEEN ABOUT 210*C. TO ABOUT 260*C., SPRAYING SAID HEATED SOLUTION INTO A CHAMBER AT ATMOSPHERIC OR SUB-ATMOSPHERIC PRESSURE, WHEREBY LIQUID IS EVAPORATED AND PYROLYSIS OF SAID DIAMMONIUM SALT TO THE MONOAMMONIUM SALT OCCURS, AND SEPARATING SOLID MONOAMMONIUM TEREPHTHALATE FROM SAID CHAMBER. IN ANOTHER EMBODIMENT, THE MONOAMMONIUM TEREPHTHALATE IS CONVERTED TO TEREPHTHALIC ACID AND DIAMMONIUM TEREPHTHALATE, WHICH SALT IS RECYCLED.

Abstract: Novel linear polymers having high melting points and suitable for use as adhesives, sealants, films, surface coatings and as chromotographic agents can be prepared from dihydrazides of methylated muconic acids either singularly or in mixtures with each other and an organic diisocyanate. The linear polymer may also be crosslinked by heat or free radicals or with ethylenically unsaturated monomers to produce useful films and coatings.
