Abstract: 3,6-Dimethyl-3-hydroxy-oct-1-ynes and -oct-1-enes and their esters with lower alkanoic acids, of the general formula I (I) where X and Y are H or the two X's and/or the two Y's together are a further bond between the carbon atoms on which they are present, and R is H, -CO-CH3, -CO-C2H5 or -CO-C3H7, their use as scents, and a process for the preparation of 3,6-dimethyl-3-hydroxy-octane. The novel compounds exhibit interesting, predominantly floral, woody, herbal and fruity notes. The alcohols of the formula I are of particular importance because they serve as intermediates for a novel and particularly advantageous method of obtaining 3,6-dimethyl-3-hydroxy-octane, a compound required in large amounts as a fragrance for soaps and detergents.

Abstract: Prepn. of aralkylamines of formula (I) by reacting a sec. amine of formula (II) with a carbonyl cpd. of formula (III) is effected in presence of hydrogen and a hydrogenation catalyst consisting of (a) platinum, (b) zinc, cadmium, manganese and/or a rare earth metal oxide, on (c) an inert carrier. (R1 is H, 1-10C aliphatic gp., 5-7C cycloaliphatic gp. or 1-6C alkoxy; A is -(CHX5)n-, -CHX6-N(X7)-CHX8- or -CHX9-O-CHX10-; R2-R4 and X1-X10 are H or 1-4C alkyl; n is 2, 3 or 4; the dotted line in (III) is an optional double bond).

Abstract: Hydrogenation catalysts, which have a specific surface area of from 50 to 150 square meters per gram, solely or partially contain crystals having a spinel structure and copper in the form of copper oxide, and have been obtained by precipitating copper and aluminum in a ratio of from 0.25 to 3 atoms of copper per atom of aluminum from their compounds in the presence of a carbonate at a pH of from 4.5 to 9 and calcining the resulting precipitate at from 300 DEG to 800 DEG C., for the catalytic preparation of propanediols by hydrogenating hydroxypropionaldehydes at not more than 300 bar pressure and from 50 DEG to 200 DEG C., and processes for the preparation of propanediols by the use of such catalysts. The propanediols obtainable by the process of the invention, in particular 2,2-dimethylpropane-1,3-diol, are valuable starting materials for the preparation of lubricants, plastics, surface coatings and synthetic resins, for example corresponding polyesters.
