Abstract
Inventia se refera la un procedeu de obtinere a N, N-dimetilamidei acidului difenilacetic, prin fosgenare, conform caruia reactia se efectueaza cu fosgen lichid în solventi aromatici inerti, la presiune atmosferica, timp de 2...3h, si temperatura de 70...150 degree C, reglata prin ratia de reflux, în prezenta dimetilformamidei drept catalizator în cantitate de 1...10% fata de acidul difenilacetic introdus, în solutia de clorura acida a acidului difenilacetic obtinuta se adauga dimetilamina în raport molar de 1:2,01...2,2:1, la temperatura de 10...50 degree C, sub agitare, timp de 1...4h, urmata de antrenarea cu vapori a solventului aromatic si filtrarea dimetilamidei obtinute.
