Process for the continuous preparation of an amine by reaction of a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group consisting of ammonia, primary and secondary amines at a temperature in the range from 60 to 300&#xb0; C. in the presence of a copper-containing catalyst, wherein the catalytically active composition of the catalyst prior to reduction with hydrogen comprises

Method for the continuous production of an amine

Method for producing carbonyl compounds

An alkinol or mixture of two or more thereof is hydrogenated by bringing the alkinol or the mixture of two or more thereof into contact with a hydrogen-containing gas in the presence of a catalyst comprising as active metal at least one metal of transition group VIII of the Periodic Table, either alone or together with at least one metal of transition group I or VII of the Periodic Table, applied to a support, wherein the support contains macropores.

Hydrogenation of alkinols using a catalyst containing macropores

Butyrolactone-preparation process

A process for hydrogenating aromatic compounds in which at least one hydroxyl group is bonded to an aromatic ring comprises bringing at least one of these compounds into contact with free hydrogen in the presence of a catalyst, wherein the catalyst comprises ruthenium and, if desired, at least one metal of transition groups I, VII and VIII in an amount of from 0.01 to 30% by weight, preferably from 0.2 to 15% by weight, based on the total weight of the catalyst, applied to a support, where the support has a mean pore diameter of at least 0.1 .mu.m, preferably at least 0.5 .mu.m, and a surface area of at most 15 m.sup.2 /g, preferably at most 10 m.sup.2 /g.

Hydrogenation of aromatic compounds in which at least one hydroxyl group

Aromatic compounds in which at least one amino group is bonded to an aromatic nucleus are catalytically hydrogenated in the liquid phase by a process in which the catalyst consists essentially of ruthenium and, optionally at least one metal of subgroup I, VII or VIII in an amount of from 0.01 to 30% by weight, based on the total weight of the catalyst, applied to a carrier which has a mean pore diameter of at least 0.1 .mu.m and a surface area of not more than 15 m.sup.2 /g.

Hydrogenation of aromatic compounds in which at least one amino group is
