Abstract
Naphthalene is hydrogenated in liq. phase to tetrahydro naphthalene with H2 gas (at 100-200 degrees C and 0.1-100 bars) with sol. catalyst contg. (a) gp. VIII metal (Fe, Co, Ni) salt (acetylacetonate) (b) AlR1R2R3 where R1R2R3 are H or 1-20C hydrocarbon, (c) tetrahydro naphthalene. (a) is a salt of 1-20C carboxylic acid sol in (c). (b) is triethyl aluminium. Concn of metal in (a) is 0.001-0.1 wt.%. Vol. ratio of catalyst soln to charge is 1:500-1:10. The catalyst improves activity and selectivity in (de)hydrogenation, isomerisation reactions.
