Abstract
PROCEDIMIENTO PARA PRODUCIR ETILENGLICOL A PARTIR DE METANOL. COMPRENDE LAS SIGUIENTES FASES: PRIMERA, SE PREPARA UNA MEZCLA FORMADA POR UN 45 A UN 97% EN PESO DE METANOL, POR UN 0,25 A UN 25% EN PESO DE PEROXIDO ORGANICO, POR UN 0,5 A UN 13% EN PESO DE FORMALDEHIDO, Y POR UN 0,5 A UN 35% EN PESO DE AGUA; SEGUNDA, LA MEZCLA FORMADA SE HACE REACCIONAR A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 200 GRADOS Y DURANTE UN TIEMPO COMPRENDIDO ENTRE 0,25 Y 8 HORAS; Y POR ULTIMO, SE AGREGA A LOS REACTIVOS UN MATERIAL BASICO EN CANTIDADES SUFICIENTES PARA REDUCIR LOS IONES DE HIDROGENO QUE SE ESTEN FORMANDO EN LA REACCION SIN REDUCIR INDEBIDAMENTE LA PRODUCCION DE ETILENGLICOL.
