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

A process for the hydrogenation of an organic compound containing at least one carbonyl group comprises bringing the organic compound in the presence of hydrogen into contact with a shaped body which can be produced by a process in which

Method for producing cyclopentanone

Method for producing 1,6-hexanediol

A process for the separation by distillation of a mixture of 1,4-butanediol and at least one 4-hydroxybutyraldehyde, its cyclic hemiacetal and its cyclic full acetals with at least one further alcohol by carrying out the distillation in the presence of an alkaline compound. The mixture to be separated preferably contains a cyclic full acetal of 4-hydroxybutyraldehyde with a further alcohol which has a lower boiling point than butanediol and also the further alcohol in free form. The process is particularly suitable for the separation by distillation of mixtures formed in the hydrogenation of maleic acid derivatives.

Method for distilling mixtures containing butanediol

Preparation of halogen-free, reactive polyisobutene

A process for preparing cyclopentanone and cyclopentene-1-carboxylic acid or an ester thereof of the formula I

Method for producing cyclopentanone and cyclopentene-1-carboxylic acid and their esters

In a process for preparing THF (tetrahydrofuran) by reaction of a 1,4-butanediol-containing reaction mixture over an acid catalyst, the reaction mixture comprises further alcohols different from 1,4-butanediol and is essentially free of water.

Preparation of tetrahydrofuran

In a process for preparing alcohols by gas phase hydrogenation of carboxylic acids or esters thereof at elevated temperature and elevated pressure in the presence of catalysts consisting of or comprising, as hydrogenating components, oxides of main group VI and/or subgroup IV, the hydrogenation is carried out
