Abstract
Inventia se refera la un procedeu de obtinere a derivatilor dinitrinici cu structura dibenzilica prin nitrarea dibenzilului, în care nitrarea se realizeaza cu un amestec de acid azotic si acid sulfuric folosind ca solvent organic pentru dibenzil unul ales dintre tetraclorura de carbon, 1,2-dicloretan, clorura de metilen, temperatura în timpul nitrarii mentinîndu-se la 20...40 degree C, dupa care se ridica la 50...60 degree C timp de 6...8h, produsul de reactie se filtreaza rezultînd un precipitat ce contine 4,4'-dinitrobenzil, care se spala si se usuca, iar filtratul-faza organica-se spala sub agitare pîna la pH neutru, se supune distilarii pentru recuperarea solventului, la temperatura de 120...130 degree C, ramînînd în blaz o topitura formata din 2,2' si 2,4'-dinitrodibenzil.
