ABSTRACT:
A primary alkyl amine and an alcohol of up to 12 carbon atoms are reacted at low temperature (50.degree.-250.degree. C.) over specific catalysts (alkali-treated catalysts generally or binary Cu/ZnO and Pd/SiO.sub.2 systems, with or without alkali treatment) to produce, with good selectivity, secondary and tertiary alkylamines of the general formula, R.sub.1 N(R.sub.2).sub.2, wherein R.sub.1 is a lower alkyl or an aryl group, and R.sub.2 is hydrogen or another lower alkyl or aryl group, with at least one of R.sub.2 's being an alkyl or aryl group.
