Optically active amines are racemized by reaction of the optically active amine in the gas phase at elevated temperature in the presence of hydrogen and a hydrogenation or dehydrogenation catalyst.

Racemization of optically active amines

In a process for racemizing optically active amines by reacting the optically active amine in the presence of hydrogen and a hydrogenation or dehydrogenation catalyst at elevated temperature, the reaction is carried out in liquid phase and the catalyst comprises the catalytically active constituents copper, silver, iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium and/or platinum and a support material selected from the group consisting of aluminum oxide, zirconium dioxide, titanium dioxide, carbon and/or oxygen compounds of silicon.

Racemizing of optically active amines

In a process for preparing bis(2-morpholinoethyl) ether by reacting diethylene glycol with ammonia under superatmospheric pressure and at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the catalytically active composition of the catalyst prior to reduction with hydrogen comprises

Preparation of bis(2-morpholinoethyl) ether

Process for preparing alcohols and/or aldehydes from olefins

Catalyst systems for producing copolymers of carbon monoxide and

A process for preparing tetrahydrofuran, which comprises reacting 1,4-butenediol diethers of the formulae I and/or II

Process for the preparation of 1,4-butanediol monoethers

Preparation of 3-pentenoic acid esters by carbonylation of alkoxybutenes

A process for the preparation of racemic amines of the formula I ##STR1## where R.sup.1 and R.sup.2 are different and R.sup.1, R.sup.2, R.sup.3 are alkyl, cycloalkyl, arylalkyl, aryl, heteroaryl and heterocyclic radicals and R.sup.3 can also be hydrogen, where the radicals can bear substituents selected from the group consisting of alkyl, cycloalkyl, alkoxy, aryloxy, amino, alkylamino and dialkylamino, which comprises simultaneously reacting in situ the corresponding optically active amine I and the secondary alcohol of the formula II and/or the unsymmetrical ketone of the formula III ##STR2## and the amine of the formula R.sup.3 NH.sub.2 in the presence of hydrogen and a hydrogenation catalyst or dehydrogenation catalyst at elevated temperature.
