Abstract
Un procedimiento perfeccionado de tratamiento de la mezcla reaccionante resultante de la oxidacion directa del hidrocarburo en ácido carboxílico, con laayuda de oxígeno molecular o de un gas que lo contiene, en fase líquida, en un solvente y enprese ncia de un catalizador disuelto en el medio reaccionante,caracterizado porque dicho procedimiento presenta: cuando la composicion de la mezcla reaccionante lo permite, una decantacion en dos fases líquidas: una fasesuperior no polar, quecontiene ese ncialmente el hidrocarburo no transformado y una fase inferior polar; una destilacion de dicha fase inferior, o dado el casode la totalidad de la mezcla reaccionante que permite separar por una parte un destilado y por otra parte, elpie de destilaci on que comprende los ácidosformados,el catalizador,los compuestos pesados,al menos una parte del solvente y eventualmente los intermediarios y subproductos de reaccion;un tratamientode purificacion por oxidacion con la ayuda deoxígeno molecular o de un gas que lo contiene o con la ayuda de dadores de oxígeno, del pie de destilacionobtenido precedentemente; una destilacion del solvente y de los intermediarios y subproductos de reaccion que todavía puedan quedar en lamezcla; unacristalizacion de l ácido carboxílico producto de la reaccion; una cristalizacion en agua del ácido carboxílico producto de la reaccion.
