Abstract

La presente invención se refiere a un método para preparar 1,1-dimetilhidrazina que comprende las etapas de: (a) alquilizar reductivamente a un temperatura entre 20 y 100°C aproximadamente, un hidrázido ácido de la fórmula: (VER GACETA) en que R representa un alquilo inferior, con formaldehido a un pH menor de alrededor de 7.5 para proporcionar la N,N-dimetil-2-acilhidrazina correspondiente; (b) dividir dicha N,N.-dimetil-2-acilhidrazina por hidrólisis; y (c) recuperar la 1,1 dimetilhidrazina de la mezcla de la reacción de la etapa (b).
