Abstract
SE PRESENTA UN PROCESO PARA LA PRODUCCION DE ACIDO TEREFTALICO QUE COMPRENDE LA EXPOSICION DE TEREFTALATO DE POLIALQUILENO A LA HIDROLISIS USANDO UNA REACCION DE AGUA CON RESPECTO AL TEREFTALATO DE POLIALQUILENO EN LA MEZCLA ANTES DE CALENTARLA Y LLEVAR A CABO LA REACCION BAJO CONDICIONES TAL QUE, A LA TEMPERATURA DE REACCION, UNA PROPORCION SIGNIFICATIVA DEL ACIDO TEREFTALICO PRODUCIDO SE ENCUENTRE EN FASE SOLIDA. EL GRADO DE RECRISTALIZACION NECESARIO PARA RECUPERAR EL ACIDO TEREFTALICO PRODUCIDO SE REDUCE DE ESTA FORMA. LA REACCION PUEDE LLEVARSE A CABO DE FORMA VENTAJOSA CON GLICOL DE ALQUILENO PRESENTE EN LA MEZCLA ANTES DE LA HIDROLISIS.
