Abstract
Prezenta inventie se refera la un procedeu de obtinere a derivatilor sulfonici prin sulfonare cu acid clorsulfonic sau trioxid de sulf a produsului lichid rezultat la piroliza deseurilor de polistiren, copolimeri acrilobutilstirenici, cauciuc stirenic polietilena sau de amestecuri ale acestor polimeri sintetici caracterizat prin aceea ca în scopul îmbunatatirii gradului de puritate a compusilor rezultati în urma sulfonarii utilizati drept agenti tensioactivi se trateaza produsul lichid avand continuturi de 60....70% stiren si dimeri ai stirenului benzen toluen etilbenzen rest cu acid clorsulfonic la temperatura de 0.....10 degree C în mediu de cloroform sau cu trioxid de sulf la temperatura de 40.....50 degree C reactia de sulfonare fiind urmata de diluare cu apa separarea stratului organic de cel apos si purificarea compusilor obtinuti prin extractie selectiva în mod în sine cunoscut.
