Abstract

La presente invencion se refiere a procesos que separan compuestos químicos deseados de otros compuestos en solucion, utilizando cromatografía manejada térmicamente, sobre adsorbentes solidos. El proceso preferido involucra principios cromatográficos que son auxiliados por la variacion de la temperatura de operacion, en las fases de separacion y elucion. También se describen procesos para el tratamiento de ácidos acuosos, para eliminar el agua y recuperar los ácidos en un solvente orgánico, tal como un alcohol.
