Abstract

520,201. Catalytic hydrogenation. BLUMENFELD, J. Oct. 14, 1938, No. 29861. Convention date, Oct. 14, 1937. [Class 1 (i)] [Also in Group IV] The catalytic hydrogenation of aldehydes and ketones for the production of the corresponding alcohols is effected in the presence of alkali alcoholates in a substantially anhydrous state. In an example sodium isopropylate is dissolved in acetone, active nickel is added, and hydrogenation effected at normal temperature and pressure. The alcohol is decanted, sodium and nickel being removed by carbon dioxide, followed if desired by rectification. In some cases the hydrogenation may be effected hot with or without pressure. The Specification as open to inspection under Sect. 9] includes tne use of alkali compounded with alcohol into solution in the medium undergoing hydrogenation." This subject-matter does not appear in the Specification as accepted.
