Abstract

La presente invención se refiere a procedimiento para separar aromáticos de mezclas de hidrocarburos de cualquier contenido en aromáticos, los cuales contienen, como componentes no aromáticos, particularmente parafinas y cocloparafinas, mediante destilación extractiva, en la que se emplean, como disolvente selectivo, morfolinas N-sustituidos, cuyos sustituyentes no presentan más de siete átomos de carbono, caracterizado porque en la mezcla de hidrocarburos que sirve de producto de partida se mantiene un contenido de no aromáticos ligeros, cuyos puntos de ebullición están situados al menos 36 grados C por debajo del punto de ebullición del compuesto aromático puro a obtener, proporcional al contenido de dicha mezcla en no aromáticos pesados cuyos puntos de ebullición están situados al menos 14 grados C por encima del punto de ebullición del compuesto aromático puro a obtener, debiendo ser de al menos 1 : 0,4 la proporción en peso de no aromáticos pesados a no aromáticos ligeros.
