Abstract
PROCEDIMIENTO DE SEPARACION Y DESDOBLAMIENTO DE LOS PRODUCTOS DE REACCION RESULTANTES EN LA ETERIFICACION DE ISOOFELINAS INFERIORES CON METANOL EN UN REACTOR. CONSISTE EN EL LAVADO CON AGUA EN PRESENCIA DE HIDROCARBUROS INERTES. LA PROPORCION DE ALCOHOL QUE TIENE METANOL Y ALCOHOLES TERCIARIOS, SE EXTRAE TOTALMENTE CON AGUA, RECOGIENDOSE LA SOLUCION ACUOSA DE EXTRACTO EN LA PARTE INFERIOR O COLECTOR DE LA COLUMNA DE LAVADO Y SIENDO TRANSFERIDA A CONTINUACION A LA COLUMNA DE DESTILACION, EN LA QUUE SON SEPARADOS POR DESTILACION EL AGUA Y LOS ALCOHOLES.
