Abstract

The invention relates to the preparation and recovery of N- alkylethylenediamines by reaction of ethylenediamine with an alkyl halide, in which the N-alkylethylenediamine is obtained substantially free of unreacted ethylenediamine by adding a hydrocarbon solvent to the alkylation reaction mixture, or to a fraction thereof containing the desired product, and then removing unreacted ethylenediamine by azeotropic distillation of the reaction mixture or fraction.
