Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partially hydrogenating aliphatic alpha,omega-dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The catalyst contains (a) a compound based on a metal selected from the group made up of nickel, cobalt, iron, ruthenium and rhodium; (b) 0.01 to 25 % by weight in relation to (a) of a promoter based on a metal selected from the group comprising of palladium, platinum, iridiu m, osmium, copper, silver, gold, chromium, molybdenum. tungsten, manganese, rhenium, zinc, cadmium, lead, aluminium, tin, phosphoru s, arsenic, antimony, bismuth, silicium, titanium, zirconium and rare earth metals; and (c) 0 to 5 % by weight in relation to (a) of a compound based on an alkaline or alkaline-earth metal, provided that component (a) not be based on iron or iron and a metal selected from th e group comprising cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group comprising titanium, manganese, chromium and molybdenum. Moreover, when component (a) is a compound based only on ruthenium or on rhodium, ruthenium and rhodium, or nickel and rhodium, promoter (b) may be dispensed with.

Abstract: Process for the isomerization of precursor allyl alcohols to product allyl alcohols in the presence of tungsten oxo(VI) complexes comprising additional nitrogen-containing ligands at temperatures of from 50 to 300° C., wherein, in the catalyst, as well as the nitrogen bases known as additional nitrogen-containing ligands, or instead of these nitrogen bases, aminoalcohols such as triethanolamine, diethanolamine, monoethanolamine, tripropanolamine, dipropanolamine, 3-amino-1-propanol, 1-amino-2-propanol, 2-amino-1-propanol, butyldiethanolamine, methyldiisopropanolamine, N,N'-bis(2-hydroxybenzyl)-1,2-diaminoethane or N-(2-hydroxybenzyl)amine are present as additional nitrogen-containing ligands. The process is particularly suitable for the preparation of tertiary product allyl alcohols, such as linalool, by isomerizing primary or secondary allyl alcohols, such as geraniol and nerol.
