Abstract

Inventia se refera la un procedeu de preparare a sarii disodice a acidului o-xililendisulfonic prin reactia dintre alfa, alfa-dibrom-orto-xilen si sulfat de sodiu la temperatura de90 degree C, prin care în scopul obtinerii unui înalt grad de puritate necesar utilizarii compusului obtinut în industria materialelor foto, se substituie bromul cu gruparea sulfonica prin transfer interfazic în prezenta catalizatorului brimura de tetrabutilamoniu, utilizînd un amestec de apa-metanol în raport în greutate de0,75 : 1.
