Abstract
PROCEDIMIENTO PARA LA OBTENCION DE NITROSOBENCENO A PARTIR DE NITROBENCENO. CONSISTE EN EFECTUAR LA REACCION A UNA TEMPERATURA DE 250 A 450 GC, EN AUSENCIA DE AGENTES REDUCTORES CONOCIDOS PARA ELLO, A PRESIONES DE 0,01 A 40 BARES, EVENTUALMENTE EN PRESENCIA DE NITROGENO, DIOXIDO DE CARBONO, AMONIACO, VAPOR DE AGUA, UN GAS NOBLE O MEZCLAS DE ESTOS. LA PRESION PARCIAL DE NITROBENCENO CON EL MARGEN ES DE 0,01 HASTA 0,5 BARES; LA PRESION TOTAL ES DE 0,5 HASTA 5 BARES. COMO CATALIZADORES SE EMPLEAN OXIDO DE MANGANESO Y OXIDO DE PLOMO, APLICADOS SOBRE UN SOPORTE TAL COMO PIEDRA POMEZ, OXIDO DE ALUMINIO, CARBON ACTIVO, AMIANTO, LADRILLO O TIERRA DE DIATOMEAS. S
