Abstract
Process for the preparation of diphenylalkenyl amines, characterized essentially by the fact that it comprises dehydrating a compound of the general formula ** formula ** With means for the dehydration of alkanols, to arrive at dinylethylalkenylamines of the general formula ** formula ** And its non-toxic acid addition salts, in which formulas A represents a linear or branched alkylene group containing not more than 6 carbon atoms, B represents an alkylamino or dialkylamino group, or a 5 or 6 membered saturated mononuclear heterocyclic group linked to the hydrocarbon a chain, through a nitrogen atom, which heterocyclic group can carry one or more alkyl groups and in the case of substituted alkyl includes at most 12 carbon atoms and R represents a hydrogen atom or an alkyl group (Machine-translation by Google Translate, not legally binding)
