Abstract

Invenţia se referă la un procedeu de obţinere a unui agent antiincrustant, pentru acoperirea suprafeţelor reactoarelor de polimerizare a monomerilor, care se obţine prin reacţia între acidul hidroximetansulfinic şi 1-naftol, în mediul de reacţie, adăugându-se sulfit acid de sodiu sau sulfit acid de potasiu, procedeul fiind realizat astfel încât, produsul rezultat să fie transparent şi clar, în lipsa contactului cu oxigenul.
