Abstract
SE DESCRIBE UN PROCESO PARA EL DESPLAZAMIENTO POSITIVO CONTRA CORRIENTE DE UN ACIDO CARBOXILICO AROMATICO DE 1 A 5 ATOMOS DE CARBONO DESDE UNA PATILLA FILTRO DE UN ACIDO POLICARBOXILICO AROMATICO QUE CONTIENE EL ACIDO CARBOXILICO ALIFATICO, EN DONDE EL LIQUIDO MADRE RETENIDO POR EL ACIDO POLICARBOXILICO AROMATICO TIENE UNA CONCENTRACION DE ACIDO CARBOXILICO ALIFATICO DE 5000 PPMW, O MENOS, BASADA EN EL PESO DEL PRESENTE ACIDO POLICARBOXILICO AROMATICO. ESTE METODO ES UTIL PARA LA FABRICACION DE ACIDO TEREFTALICO CRUDO QUE SE UTILIZA TRAS LA PURIFICACION PARA LA PREPARACION DEL POLIESTER USADO PARA LA FABRICACION DE TEJIDOS, FIBRAS Y BOTES DE PLASTICO.
