A method for the production of heterocylic quaternary ammonium compounds and/or guanidine compounds, wherein the carboxylate of the corresponding heterocyclic quaternary ammonium cation and/or guanidine cation containing the carboxylate anion of general formula R'-COO- (I), wherein R' represents hydrogen; C<SUB>1</SUB>- C<SUB>7</SUB>-alkyl; -OOC-(CH<SUB>2</SUB>)<SUB>n</SUB>- wherein n is equal to 0, 1 or 2; R"OOC-(CH<SUB>2</SUB>)<SUB>n</SUB>- wherein n is equal to 0, 1 or 2; -OOC-CH=CH-; R"OOC-CH=CH-; ethenyl; 2-propenyl; or a phenyl group which is unsubstituted or substituted by one to five independently selected groups from the series of C<SUB>1</SUB>- C<SUB>6</SUB>-alkyl, hydroxy, carboxylate (-COO-), carboxy (-COOH) and C<SUB>1</SUB>- C<SUB>6</SUB>- alkyloxy carbonyl (-COOR<SUP>#</SUP> wherein R<SUP>#</SUP> equals C<SUB>1</SUB> - C<SUB>6</SUB>-alkyl) and R" equals hyrogen or C<SUB>1</SUB>- C<SUB>6</SUB>-alkyl; is reacted with an inorganic or organic protonic acid with a pK<SUB>a</SUB>-value of von < 14 measured at 25 °C in an aqueous solution. |
