A process for the preparation of heterocyclic salts of quaternary ammonium - compounds and / or guanidinium - compounds of high purity

摘要

A process for the preparation of heterocyclic salts of quaternary ammonium - compounds and / or guanidinium - compounds, in which the carboxylate of the corresponding heterocyclic quaternary ammonium - cation and / or guanidinium - cation, which the carboxylate - anion of the general formula (i)R '- coo^-,in theR '· hydrogen;· C.₁- to c₇-Alkyl;· ^-ooc - (ch₂)_n- with n is equal to 0, 1 or 2;· R "ooc - (ch₂)_n- with n is equal to 0, 1 or 2;· ^-ooc - ch = ch-;· R "ooc - ch = ch-;· Ethenyl;· 2 - Propenyl or· an unsubstituted or substituted by one to five independently of one another are selected groups selected from the group consisting of c₁- to c₆-Alkyl, hydroxy, carboxylate (- coo^-), Carboxy (- cooh) and c₁- to c₆-Alkoxycarbonyl (- coor^# with r^# equal to c₁- to c₆-Alkyl) substituted phenyl groupandR "is hydrogen or c₁- to c₆-Alkylcontains,with an inorganic or organic protonic acid with a pk_a-Value of ≦ 14, measured at 25°C. in aqueous solution.
