Abstract
SE DESCRIBE UN PROCESO PARA PRODUCCION RENTABLE DE CIANURO DE HIDROGENO A UNA TEMPERATURA DE REACCION ENTRE 250 Y 550 MEDIANTE REACCION DE DESHIDRATACION CATALITICA DE FORMAMIDA QUE COMPRENDE EL EMPLEO COMO CATALIZADOR DE UN OXIDO DE MANGANESO (MNO) Y/O UN OXIDO DE MAGNESIO (MGO) MODIFICADOS CON UN METAL ALCALINO (NA, K, RB, CS, ETC.). EL MENCIONADO PROCESO ES CAPAZ DE PRODUCIR CIANURO DE HIDROGENO CON INCREMENTADA EFICIENCIA DE CONVERSION DE FORMAMIDA Y CON ELEVADA SELECTIVIDAD MIENTRAS SE MINIMIZA LA PRODUCCION DERIVADA DE AMONIACO. EL EMPLEO DE UN CATALIZADOR QUE COMPRENDE COMO COMPONENTE PRINCIPAL MNO MODIFICADO CON METAL ALCALINO ES PARTICULARMENTE EFECTIVO PARA PROLONGAR SU VIDA UTIL Y POSIBILITA UNA OPERACION ESTABLE A LARGO PLAZO.
