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.
