Abstract
UN METODO DE PRODUCIR ACETONITRILO EN BRUTO ESTABILIZADO (P.EJ. ACETONITRILO QUE HA SIDO TRATADO PARA ELIMINAR SUSTANCIALMENTE LA POLIMERIZACION DEL ACETONITRILO EN VAPORIZACION) QUE COMPRENDE MEZCLAR ACETONITRILO CRUDO, UNA BASE FUERTE Y ALDEHIDO JUNTOS, CALENTAR A LA TEMPERATURA DE REFLUJO DE LA MEZCLA PARA ESTABILIZAR EL ACETONITRILO CRUDO Y RECUPERAR EL ACETONITRILO ESTABILIZADO. ESTE ACETONITRILO ESTABILIZADO ES UTILIZADO PARA MANUFACTURAR CIANURO DE HIDROGENO.
