Title: Process for hydrogenating naphthalene and alkylnaphthalenes
IPC: C07C5/11
Filed: 1973-05-22
Abstract: 1427749 Tetrahydronaphthalenes INSTITUT FRANCAIS DU PETROLE 22 May 1973 [23 May 1972] 24286/73 Heading C5E Tetrahydronaphthalene and alkyl tetrahydronaphthalene are produced by reacting naphthalene, or alkylnaphthalene respectively, with hydrogen in the presence of a catalyst which has been prepared in the absence of naphthalene or alkylnaphthalene by adding a solution of at least one cobalt salt to at least one trialkylaluminium and/or alkyl aluminium hydride in the liquid phase and heating the mixture at 50-200‹ C. during or after the mixing. The cobalt salt is preferably added in such an amount that the atomic ratio of aluminium to cobalt is within the range 2 : 1 to 4 : 1. The catalyst can be prepared by pouring a solution of cobalt octoate, naphthenate, stearate or acetylacetonate in tetrahydronaphthalene or decahydronaphthalene into triethyl-, triisobutyl- or triacyl-aluminium or diisobutyl aluminium hydride; the aluminium compound can be used either as the pure liquid or dissolved in tetrahydronaphthalene. The hydrogenation can be carried out at 90- 200‹ C. and 0À1-50 bars in an autoclave using an amount of catalyst equivalent to 5-300 parts cobalt per million parts of naphthalene or alkylnaphthalene. In examples pure tetrahydronaphthalene is produced from naphthalene, a mixture of 2-methyl and 6-methyl tetrahydronaphthalene is produced from #-methylnaphthalene, and a mixture of 1-methyl, 6- methyl and 5-methyl tetrahydronaphthalene is produced from a mixture of α- and #-methylnaphthalenes.

Abstract: 1304316 Coated particles MARATHON OIL CO 19 April 1971 [25 March 1970] 25051/ 71 Heading B2E [Also in Division C1] Carbon particles having an average diameter of less than 2.5 microns are coated with an organic barrier against oxygenation, which barrier is preferably a liquid having a viscosity of 10-70 Saybolt Universal Seconds at 100‹F, by mixing the organic barrier material with methanol to form a solution containing 1-50% by weight organic barrier thereafter mixing the resulting solution with carbon particles in an amount of 0.5-10% by weight of barrier material excluding methanol based on the weight of the carbon to form a mass of kneadable or extrudable consistency, subjecting the mass to high-torque mixing under a non oxidising atmosphere, subdividing the mass and removing methanol by evaporation while leaving the organic barrier on the surface of the carbon particles. The carbon particles may be produced by grinding carbonaceous material in a fluid-energy mill in a non oxidising atmosphere, preferably steam. The carbonaceous material may be petroleum coke, fluid petroleum coke, anthracite coal, coke derived from coal, char. Residual organic liquid barriers are paraffinic and olefinic oils, catalytic slurry oil, fatty acids, fatty acid salts, catalytic cycle oils, and aromatic oils. As shown in the drawing granulated fluid petroleum coke is fed from bin 1 to mill 2 utilizing steam as a grinding fluid at a sonnet velocity at 400-800‹F. The mill has opposed nozzles which cause a stream of particles to impinge on a second stream of particles and the grinding process is continued with particles having average particle size below 1.5 microns and 99% by weight having size below 3 microns being continuously withdrawn from classify 3 of the mill. Over size particles are returned to the pulverizer. Steam and ground carbon of the desired particle size are propelled by steam pressure to collector 6 which recovers the particles and thence the steam. The particles then travel to hopper 8 through which an inert atmosphere is constantly bled. The particles are admitted from hopper 8 to inert blanketed ribbon-type drive blender 9 wherein they are uniformly sprayed with a mixture of methanol and an aromatic oil from mixing tank 12. The interior of the blender 9 is then heated by heating elements 15 to remove methanol which is swept away by the inert atmosphere and recovered by condenser 17 for recycle. The coated particles are fed to pelletiser 17. The coated particles are useful in the manufacture of mechanical rubber goods, tyre carcasses and tread stocks, rubber extrusions, and similar materials made from vulcanisable elastomers such as natural and synthetic rubber, styrenebutadiene copolymer, butadiene-acrylonitrile copolymer, butyl rubber, ethylene-propylenediolefine terpolymers, polyisoprene, vulcanizable polymeric elastomeric material containing double bonds and derived from chloroprenes or fluoroprenes.
