Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CIANURO DE HIDROGENO. EN EL INTERIOR DEL TUBO DE REACCION SE ALOJA UN TUBO DE INTRODUCCION (FIGURA), AMBOS DE MATERIAL CERAMICO, QUE POSEE VARIOS ORIFICIOS POR LOS QUE SE INSUFLA LA MEZCLA GASEOSA DE AMONIACO Y METANO (U OTRO HIDROCARBURO ALIFATICO DE CADENA CORTA) A GRAN VELOCIDAD Y A PRESION DE 1,2 BARES ABSOLUTOS. TAL SALIDA DE LA MEZCLA DE GASES INDICADA SE PRODUCE TANGENCIALMENTE AL TUBO DE INTRODUCCION. EL GAS PRODUCTO ASI OBTENIDO SE PASA A TRATAR YA EN FORMA HABITUAL.
