Abstract

Se obtine în mod continuu, dian prin condensarea fenolului cu acetona la trecerea printr-un pat de catalizator de tip schimbator de ioni si anume copolimer sulfonat de stiren si divinilbenzen, caracterizat prin aceea ca, amestecul de reactie continînd o prima portie de acetona se trece prin primul pat de catalizator la temperatura de 60...85 degree C si dupa completarea cu a doua portie de acetona prin al doilea pat de catalizator la temperatura de 65...90 degree C, cu o viteza liniara de curgere a amestecului de reactie mentinut la temperatura de 70...95 degree C pîna la definitivarea reactiei.
