Procedure to prepare quaternary ammonium salts, of formula: ** (formula-01)**; **(formula-02)** where N=< represents a tertiary amine; N =< represents an unsaturated amine; R2, R3 and R4, which may be the same or different, each represent an element chosen from a hydrogen atom, a C1-C8 open chain alkyl group or a cycloalkyl or cycloalkenyl group with up to 8 carbon atoms, an alkoxyalkyl group C1-C8, a C1-C8 acyloxyalkyl group, a C1-C8 haloalkyl group. An aryl group, a substituted aryl group, the substituents of which are selected from halogen atom, O-C1-C4 lower alkyl group, O-acyl group, nitro group, carboxyl group and carboethoxy group. |
