Preparation of .alpha.,.omega.-aminoalcohols of the general formula I

Preparation of .alpha.,.omega.-aminoalcohols

A process for the preparation of a 2-(3-aminopropyl)-cycloalkylamine of the general formula I ##STR1## in which the subscript n is an integer from 1 to 4, from a 2-(2-cyanoethyl)-cycloalkanone of the general formula II ##STR2## in which the subscript n has the meaning stated, wherein the following stages are carried out in discrete reaction chambers:

Preparation of 2-(3-aminopropyl)-cycloalkylamines

A process for the preparation of a 2,2-disubstituted pentane-1,5-diamine of the formula I ##STR1## where R.sup.1 and R.sup.2, independently of one another, are C.sub.1 - to C.sub.10 -alkyl or C.sub.2 - to C.sub.10 -alkenyl or together are a C.sub.4 - to C.sub.7 -alkylene chain which is unsubstituted or monosubstituted to pentasubstituted by C.sub.1 - to C.sub.4 -alkyl, from a 2,2-disubstituted 4-cyanobutanal of the formula II ##STR2## where R.sup.1 and R.sup.2 are as defined above, comprises, in two spatially separate reaction spaces,

Preparation of 2,2-disubstituted pentane-1,5-diamines

A catalyst for the hydrogenation of unsaturated aliphatic compounds having a content of 20-70% w/w of nickel oxide, 25-45% w/w of zirconium oxide and 5-40% w/w of copper oxide, based on the oxidic, unreduced catalyst.

Catalyst for the hydrogenation of unsaturated aliphatic compounds

A process for the preparation of saturated alcohols by catalytic hydrogenation of acetylenic alcohols at a temperature of from 50.degree. to 200.degree. C. and under a pressure of from 30 to 320 bar, wherein the catalyst used has a content of from 20 to 75% of nickel oxide, from 10 to 75% of zirconium dioxide and from 5 to 50% of copper oxide, by weight of the oxidic, unreduced catalyst.
