Derivatives of n, n - diacylamines of the general formula i: the radicals r¹ to r⁵ different, but also may be equal and for: h, ch₃, C.₂H₅, as well as branched or unbranched alkyl and cycloalkyl groups having from 3 to 20 carbon atoms, as well as for arylalkyl groups with 7 to 20 carbon atoms, wherein the aromatic radicals can also be substituted by halogens, (c₁-C.₄)-Alkyl -, (c₁-C.₄)-Alkoxy -, (c₆-C.₁₄)-Aryloxy -, cyan -, nitro -, amino -, (c₁-C.₄)-Alkylamino -, (c₁-C.₄)-Dialkylamino groups, as well as for aromatic radicals having 6 to 14 carbon atoms, which by halogens, (c₁-C.₄)-Alkyl -, (c₆-C.₁₄)-Aryl -, (c₁-C.₄)-Alkoxy -, (c₆-C.₁₄)-Aryloxy -, amino -, (c₁-C.₄)-Alkylamino -, (c₁-C.₄)-Dialkylamino -, nitro -, cyan -, (c₂-C.₅)-Alkoxycarbonyl may be substituted, and r¹ to r⁵ is also possible to use heterocyclic radicals which can be substituted by halogen -, (c₁-C.₄)-Alkyl -, (c₆-C.₁₄)-Aryl -, (c₁-C.₄)-Alkoxy -, (c₆-C.₁₄)-Aryloxy -, nitro -, cyan -, (c₂-C.₅)-Alkoxycarbonyl groups may be substituted and heterocyclically substituted alkyl groups, wherein ar³ for aromatic radicals having 6 to 14 carbon atoms, the by halogens, (c₁-C.₄)-Alkyl, (c₆-C.₁₄)-Aryl, (c₁-C.₄)-Alkoxy -, (c₆-C.₁₄)-Aryloxy -, amino -, (c₁-C.₄)-Alkylamino -, (c₁-C.₄)-dialkylamino -, nitro -, cyano, (c₂-C.₅)-Alkoxycarbonyl may be substituted, if x = oh the compounds of symmetrically substituted, and the substances..
