Abstract
Inven'ia se refera la un procedeu de obtinere a metacrilatului de glicidil prin esterificarea directa a aciduluimetacrilic cu epiclorhidrina si anume reactia se desfasoara într-o singura faza la raporturi molare epiclorhidrina acid metacrilic de 4/1......8/1 în prezenta de NaOH în stare solida în cantitate de 1.....1,2 mol/mol acid metacrilic si catalizator tripopilamina în concentratie 1....9% fata de acidul metacrilic dupa care produsul de reactie se separa prin distilare fractionata de clorura cuprica drept inhibitor de blaza în concentratie de 0,2....0,6% fata de produsul brut alaturi de inhibimetoxifenolului în concentratie de 0,2.....1%.
