Abstract

Method for the hydrogenation of naphthalene to 1,4-dihydronaphthalene, which includes the steps of reacting naphthalene, sodium and an alcohol in an inert solvento to form sodium alkoxide and hydrogenating naphthalene to 1,4-dihydronaphthalene, adding water to the mass of reaction to convert the sodium alkoxide to the alcohol and form an aqueous layer containing sodium hydroxide, separate the aqueous layer from the remainder of the reaction mass and wash the remainder of the reaction mass to remove the residual alcohol and sodium hydroxide, characterized because it comprises carrying out the hydrogenation of the naphthalene in solution in an inert solvent for the naphthalene in a weight ratio to the naphthalene in the order of approximately 4: 1 to approximately 6: 1, to facilitate thereby the separation of the aqueous layer containing sodium hydroxide of 1,4-dihydronaphthalene, increase the yield of 1,4-dihydronaphthalene and reduce the formation of 1,2-dihydronaphthalene.
