Catalysts for the production of alcohols from olefines (other than ethylene) and steam are compounded from an oxide of calcium, barium, strontium or magnesium, and if desired boron, and an amount of phosphoric acid more than enough to form the orthophosphates but less than enough to form the metaphosphates of the metals. The catalysts may be used as granules or flakes or on supports such as electrode carbon, and a drying oil may be used in their preparation as described in Specification 404,115. A suitable catalyst may be prepared from 1 mol CaO, 0,5B2O3, 2,6H3PO4, the mixture being evaporated, with the addition of 5 per cent of linseed oil during the final stages. The product is baked at 200 DEG C., tabletted with an additional 3 per cent of linseed oil, and again baked at 200 DEG C. Specifications 407,722, [Group IV], and 408,313 also are referred to.ALSO:Olefines other than ethylene, such as propylene, butene-1 or -2 and isobutylene are reacted with steam in presence of a solid catalyst compounded from an oxide of calcium, barium, strontium or magnesium and, if desired, boron, and an amount of phosphoric acid more than enough to form the orthophosphates of the metals, but less than enough to form the metaphosphates and the normal phosphate of the boron if present. The reaction may be effected at atmospheric or increased pressure. The catalysts may be used as granules or flakes or upon inert supports such as electrode carbon, and a drying oil may be used in their preparation as described in Specification 404,115, [Group III]. The temperature of the reaction may be 100--350 DEG C. and the pressure may be up to 250 atmospheres. A suitable catalyst may be prepared from 1 mol. CaO, 0,5 B2O3, 2,6 H3PO4, the mixture being evaporated with the addition of 5 per cent of linseed oil during the final stages. The product is baked at 200 DEG C., tabletted with an additional 3 per cent of linseed oil and again baked at 200 DEG C. Specifications 407,722 and 408,313 also are referred to.
