Abstract

UN PROCEDIMIENTO NUEVO PARA LA RECUPERACION DE ACIDO ADIPICO DE UNA LEJIA MADRE ACUOSA PRESENTADA POR LA ELABORACION TECNICA DEL ACIDO ADIPICO POR MEDIO DE UNA CRISTALIZACION SUCESIVA DE LOS ACIDOS ADIPICOS DISUELTOS, EN DONDE SE MEZCLA LA LEJIA MADRE DENTRO DE UN AREA DE TEMPERATURA DE 30 A 60 C CON UNA CANTIDAD DE UNA SOLUCION ACUOSA DE ACIDO ADIPICO CON UN CONTENIDO DE ESTE DE 0,5 A 6% DEL PESO, QUE EL CONTENIDO DE LA MEZCLA EN ACIDO NITRICO, SIN TENER EN CUENTA LOS COMPONENTES ORGANICOS, COMPUTADO COMO HNO SUB 3, SE REBAJA DE 52 HASTA 60% DEL PESO A UN 35 HASTA UN 50% DEL PESO, DESPUES LA MEZCLA, DENTRO DE UN INTERVALO DE MEDIA A CINCO HORAS, SE ENFRIA AL MENOS 5 C, LO QUE AISLA EL ACIDO ADIPICO EN CRISTALIZACION POR MEDIO DE FILTRACION Y ALIMENTA EL FILTRADO OBTENIDO DE LA ELABORACION DESTILADA DE ACIDO GLUTARICO.
