Abstract
PROCEDIMIENTO PARA SEPARAR METANOL DESDE EL PRODUCTO DE REACCION OBTENIDO EN UN REACTOR EN LA ETERIFICACION DE ISOOLEFINAS C<4 HASTA C<7 CON METANOL. LA EXTRACCION DE ALCOHOL CON AGUA, SE EXTRAE EN UNA PROPORCION METANOL/AGUA DE 1:1,5 A 1:10 A TEMPERATURA DE 20 C A 60 C; A CONTINUACION SE DESTILA EL EXTRACTO ACUOSO OBTENIDO CON EL FIN DE SEPARAR LA PORCION DE ALCOHOL Y RETIRAR EL METANOL POR LA PARTE SUPERIOR DESDE LA COLUMNA DE DESTILACION Y SE RETIRAN LOS ALCOHOLES TERCIARIOS COMO UNA CORRIENTE RETROGRADA DESDE UN PLATO CON UNA ELEVADA CONCENTRACION DE LOS MISMOS, RECIRCULANDOLOS A UNA COLUMNA DE LAVADO.
