Abstract

Un procedimiento para preparar tereftalato de politrimetileno a partir de 1,3-propanodiol y tereftalato de dimetilo, donde una corriente desubproducto que contiene carbonilo se purifica mediante el tratamiento con un catalizador ácido. El procedimiento de preparacion del tereftalato depolitrimetileno comprende hacer reaccionar 1,3-propanodiol y tereftalato de dimetilo en condiciones de reaccion de esterificacion y destilar y condensarlas corrientes de subproducto de metanol y 1,3-propanodiol que contienen compuestos carbonílicos. La corriente de subproducto condensado a ser tratadase trata con un catalizador ácido tal como una resina de intercambio de iones ácida para reducir el contenido de carbonilo de la corriente.
