Abstract
A process for obtaining tertiary amines of the general formula ** (See formula) ** where R represents hydrogen, an alkyl or alkoxy group, and Z a straight or branched chain alkyl or alkenyl radical, and their quaternary ammonium compounds, characterized in that nitriles of the general formula ** (See formula) ** where Z has the meaning indicated above, they are reacted in the known manner with benzylmagnesic halides, which may or may not be substituted on the phenyl radical, all in the presence of solvents, after which the reaction mixture is disaggregated by acidification and, if necessary, the products of the reaction are converted into their quaternary ammonium compounds.
