Aminomono- or di-[(poly-n-butoxy)-n-butylamino]-(poly-n-butoxy)-n-butylamines of the general formula I

Aminomono- or

N,N'-dialkyl-substituted cyclic urea derivatives of the general formula I ##STR1## where R.sup.1 and R.sup.2 are each alkyl of 1 to 8 carbon atoms and A is CR.sup.3 R.sup.4 -CR.sup.5 R.sup.6 - or CR.sup.3 R.sup.4 -CR.sup.5 R.sup.6 -CR.sup.7 R.sup.8, where R.sup.3 to R.sup.8 are each hydrogen or alkyl of 1 to 17 carbon atoms, are prepared by reacting a diamine of the formula II ##STR2## with carbon dioxide, by a method in which the reaction is carried out in the gas phase in the presence of an oxide of an element of main group three or four or subgroup two to six of the Periodic Table, or a mixture of these, or in the presence of an aluminum silicate or magnesium silicate. 1,3,4-trimethyl-2-imidazolidinone is used as a polar solvent at low temperatures.

Preparation of N,N'-dialkyl substituted cyclic urea derivatives

A process for the preparation of tertiary alkylamines having a total of up to 9 carbon atoms by reacting a dialkylamine with a C.sub.2 -C.sub.4 -alcohol in the presence of a hydrogenation/dehydrogenation catalyst which contains essentially only copper as the hydrogenating/dehydrogenating catalytic metal is proposed, wherein the reactants

Preparation of trialkylamines

In preparing or reacting alkanolamines, especially at high temperatures, the use of substantially nickel-free alloy steels prevents corrosion and discoloration.

Process and apparatus for preparing or reacting alkanolamines

Compounds of the general formula ##EQU1## which may be used in place of malondialdehyde in synthesis reactions are obtained in a one-step reaction form dimethylformamide, phosgene and an alkyl vinyl ether.
