Abstract

Catalysts suitable for the selective hydrogenation of unsaturated aldehydes are prepared by depositing the oxide and/or hydroxide of a platinum group metal on a solid mildly alkaline supporting material, treating the product with an aqueous alkali metal hydroxide, carbonate or bicarbonate solution, and reducing the oxide to the metal. The platinum group metals are ruthenium, rhodium, palladium, osmium, iridium and platinum. Supporting materials mentioned are solid, substantially water-insoluble metal oxides, hydroxides, basic oxides, carbonates and basic carbonates, e.g. alumina, magnesia, titania and chromia; charcoal; silica gel and pumice. If the support is not intrinsically alkaline (e.g. magnesia) it is rendered mildly alkaline, e.g. by impregnating with a solution of an alkali metal hydroxide, carbonate or bicarbonate and drying. The metal oxide is deposited by contacting the support with a solution of a platinum group metal compound in an organic solvent. Solvents mentioned are C1-4 primary and secondary aliphatic alcohols; acetone and methyl ethyl and diethyl ketone; esters containing up to four carbon atoms; 2-ethoxy and 2-butoxy ethanol; dioxan and dihydropyran; and esters of sufficiently high M.W. to offset the hydrophilic character of the glycol group, e.g. hexylene glycol and 2-ethylhexan-1:3-diol. The solvents preferably contain 1 to 15 vol. per cent of water. The carrier with the deposited oxide is washed and then treated with dilute alkali solution (e.g. 1 wt. per cent) and may be reduced either prior to or in the course of the hydrogenation reaction in which it is to be used. In an example magnesia is treated with sodium carbonate and dried, the product then being successively treated with palladous chloride in acetone, washed, drained, treated with 1 per cent sodium carbonate solution, washed and dried. The product was reduced in the hydrogenation reactor wherein it was to be used. According to the Provisional Specification similar catalysts may be prepared wherein the platinum group metal compounds are replaced by compounds of other metals, e.g. auric, mercuric and uranyl chlorides and the trichlorides of the rare earth metals. The organic solvents mentioned therein also include acetals. Specification 813,382 is referred to.
