Abstract:
The invention relates to a continuous process, carried out in two steps, for the cyanoalkylation of compounds having one or more NH functions by reaction thereof with carbonyl compounds and hydrocyanic acid, in which the first step is carried out without pressure at a temperature which is below the boiling point of the reaction mixture.
