The invention relates to a method for producing arylpoly(oxalkyl)- benzyldimethyl-ammonium derivatives of formula (1) by conversion of compounds of formulas (2) and (3), wherein X= Br, CI, S-SO3 with R = alkyl, alkylaryl; R1 = H, C1-to C16-alkyl or O-C1 to O-C16-alkyl in ortho-, meta- or para- position; R2 = H, C1- to C4-alkyl or O-C1- to O-C4-alkyl; R3 = H, C1- to C16- alkyl or O-C1- to O-C16-alkyl in ortho-, meta- or para-position, and n = 1, 2, 3 or 4, at temperatures between 60 and 160 ~C, in a solvent under the pressure produced in a closed reaction container.
L'invention concerne un procédé de fabrication de dérivés d'arylpoly(oxalkyle)benzyldiméthylammonium de formule (1) par transformation de composés des formules (2) et (3) dans lesquelles X = Br, CI, S-SO¿3? avec R = alkyle, alkylaryle; R¿1? = H, C¿1?- à C¿16?-alkyle ou O-C¿1? à O-C¿16?-alkyle en position ortho, méta ou para; R¿2? = H, C¿1?- à C¿4?-alkyle ou O-C¿1?- à O-C¿4?-alkyle; R¿3? = H, C¿1?- à C¿16?-alkyle ou O-C¿1?- à O-C¿16?-alkyle en position ortho, méta ou para, et n = 1, 2, 3 ou 4, ladite transformation étant effectuée dans un solvant à des températures allant de 60 à 160 ·C, sous la pression produite dans le récipient de réaction fermé.
