Abstract

Inventia se refera la un procedeu de obtinere a N-metilpirolidonei, care consta în aceea ca produsul amidat se trateaza cu o fractiune de N-metilpirolidona proaspat rectificata, astfel încît, dupa doua ore de trecere prin reactorul de ciclizare, sa rezulte o masa de reactie cu 70...85% N-metilpirolidona stabila, care, în final, se rectifica în mod cunoscut.
