IN THE PROCESS FO CARRYING OUT AMMOXIDATION REACTIONS USING V2O5 AS CATALYST, THE IMPROVEMENT WHICH COMPRISES EMPLOYING SAID V2O5 IN THE FORM OF A MOLTEN EUTECTIC MIXTURE WITH K2O.
Abstract:
PARAFFINS RANGING FROM C6 TO AND INCLUDING SOLID PARAFFINS ARE ISOMERIZED BY CONTACTING THE PARAFFINIC FEED IN LIQUID PHASE, PREFERABLY AT 10-80*C. WITH AN ADMIXTURE OF ALCL3 AND A PARTIALLY DEHYDRATED ADSORBENT COMPRISING ALUMINA, SILICA OR ALUMINSOLICATE HAVING CERTAIN PORE SIZE AND SURFACE AREA CHARACTERISTICS, IN THE PRESENCE OF AN ADAMANTANOID SUPRESSOR SELECTTED FROM ADAMANTANE, ALKHYLADAMANTANES, DIAMANTANE AND MONOALKYLDIAMANTANES. THESE ADAMANTANOID SUPPRESSORS HAVE BEEN FOUND TO BE HIGHLY EFFECTIVE IN SUPPRESSING UNDERSIRABLE SIDE REACTIONS WHILE ALLOWING THE ISOMERIZATION REACTION TO PROCEED. PREFERABLY A MINOR AMOUNT OF HCL OR SATURATED HALOHYDROCARBON IS ALSO PRESENT AS A PROMOTER, THE COMBINATION OF ALCL3, THE ADSORBENT AND THE HCL OR HALOHYDROCARBON PROMOTER RESULTS IN A HIGHLY ACTIVE ISOMERIZATION CATALYST.
Abstract:
A CONTINUOUS PROCESS FOR CARRYING OUT REACTIONS IN A MOLTEN SALT WHICH ACTS AS A REACTION CATALYST BY FEEDING REACTANT GASES TO THE SALT IN A MANNER WHICH LIFTS SPENT SALT AWAY FROM FRESH REACTANT GASES AND FRESH MOLTEN SALT, AND EFFECTING REGENERATION OF THE CIRCULATING SPENT SALT.
Abstract:
HALOGENATED DERIVATIVES CONTAINING ADAMANTANE NUCLEUS ARE PRODUCED BY ADMIXING, IN THE PRESENCE OF STRONG SULFURIC ACID, ADAMANTANE OR ALKYL-SUBSTITUTED ADAMANTANT WITH A SELECTED HALO-YIELDING SALT OF AN ALKALI OR ALKALINE EARTH METAL, OR A CORRESPONDING HYDROGEN HALIDE.
Abstract:
It has been found that the efficiency of shock wave reactions can be greatly improved by using mercury vapor as a diluent in the reaction gas. By using reduced pressure in the reaction gas Hg mixture the boiling point of the Hg is reduced and after the reaction the Hg is easily separated merely by allowing the product gas to come to atmospheric pressure whereupon the Hg condenses out. Even at pressures of atmospheric or greater the Hg is easily separated from the product gas because of its high boiling point.
WHERE R1 AND R2 ARE HYDROGEN OR HYDROCARBLY RADICALS HAVING 1 TO 20 CARBON ATOMS AND N REPRESENTS THE NUMBER OF SUCH REPEATING UNITS WHICH ARE PRODUCED. THESE THERMOPLASTIC RESINS HAVE EXCEPTIONAL OXIDATION STABILITY, CHEMICAL INTERTNESS AND HIGH HEAT DISTORTION TEMPERATURES AND ARE USEFUL IN THE MANUFACTURE OF MOLDED AND EXTRUDED PRODUCTS.
Abstract:
Propylene trimer methyl ether is of interest as a non-air polluting solvent; however, in the production of the ether, there is a major proportion of unreacted propylene trimer from which the ether must be separated. Distilling the propylene trimer methyl ether out of the ether-trimer mixture results in up to 30 percent degradation of the ether. By adding 0.1-10 weight percent quinoline to the distillation mixture, however, reduces degradation loss to less than 5 percent.

Hydrogenation of a mineral oil containing aromatic hydrocarbons by use of a hydrogenation catalyst comprised of a Y-zeolite containing arsenic.
Abstract:
Conjugated dienes of polycyclic naphthenes having three to 11 rings of five to six carbon atoms each of which at least three are adjacent fused rings are produced by contacting the polycyclic naphthenes with a strong acid and a monool or diol of an adamantane hydrocarbon having zero to four alkyl groups with at least one alkyl group at a non bridgehead position when the number of alkyl groups is four at a reaction temperature between the freezing point of the acid and 50* C., and recovering a polycyclic conjugated diene from the reaction mixture.
