Abstract
Procedimiento para la preparación de hidrazobenceno por hidrogenación catalítica alcalina de nitrobenceno con hidrógeno en solución alcohólica, caracterizado porque como agente alcalino se utiliza un alcoholato de metal alcalino y/o un hidróxido de metal alcalino, y porque la hidrogenación se lleva a cabo a presiones >> 1 bar y a temperaturas de hasta 120ºC, preferentemente de hasta 90ºC, manteniéndose la mezcla de reacción en movimiento turbulento.
