Abstract
Inventia de fata se refera la un procedeu de preparare a sarii disodice a acidului oxililendisulfonic, prin reactia dintre alfa alfa prim-dibrim-o-xilen cu sulfit de sodiu în raport molar de 1 : 0,9 si în prezenta bromurii de tetrabutilamoniu drept catalizator. Reactia are loc într-un sistem heterogen specific catalizei de transfer interfazic toluen: apa, în raport în greutate de 1: 1 la temperatura de 65 degree C, timp de 25 h.The present invention relates to a process for the preparation of the disodium salt of oxylyndisulphonic acid by the reaction of alpha-prima-dibrim-o-xylene with sodium sulphite in a molar ratio of 1: 0.9 and in the presence of tetrabutylammonium bromide as a catalyst . The reaction takes place in a heterogeneous system specific for toluene: water interfacial transfer catalyst in a 1: 1 weight ratio at 65 ° C for 25 hours.
