Abstract
PROCEDIMIENTO DE OBTENCION DE ETILENGLICOL. SE HACE REACCIONAR HASTA APROXIMADAMENTE 97% EN PESO DE METANOL CON 0,25 A 25% EN PESO DE UN PEROXIDO ORGANICO, A UNA TEMPERATURA DE 100 A 200<025>C DURANTE UN TIEMPO PROXIMO ENTRE 0,25 HORAS Y 8 HORAS. EL PEROXIDO TIENE UN GRUPO ALQUILO O ARALQUILO CON 3 A 12 ATOMOS. ADICIONALMENTE SE AÑADE UN MATERIAL BASICO PARA REDUCIR LOS IONES HIDROGENO; DICHO MATERIAL BASICO EMPLEADO ES UN HIDROXILO ALCALINO O ALCALINOTERREO, LAS SALES DE DICHOS HIDROXIDOS Y UN ACIDO DEBILMENTE IONIZADO. EL MATERIAL BASICO EMPLEADO QUEDA DENTRO DE LA ESCALA DE 3.000 PARTES POR MILLON BASADA EN LA MEZCLA DE REACCION TOTAL.
