Abstract
UN PROCEDIMIENTO PARA LA PREPARACION DE UN POLIESTER DE 1,3 PROPANODIOL QUE COMPRENDE LA PUESTA EN CONTACTO DE UNA CORRIENTE ACUOSA QUE CONTIENE UN SUBPRODUCTO ACROLEINA CON UNA BASE DURANTE UN TIEMPO EFICAZ PARA REDUCIR EL CONTENIDO DE ACROLEINA DE LA CORRIENTE ACUOSA. EN UNA REALIZACION ESPECIFICA, UN PROCEDIMIENTO PARA LA PREPARACION DE UN TEREFTALATO DE POLIPROPILENO COMPRENDE LAS ETAPAS DE: (A) PUESTA EN CONTACTO DEL 1,3 PARA OBTENER UNA MEZCLA DEL PRODUCTO DE REACCION QUE CONTIENE UN TEREFTALATO DE POLIPROPILENO Y UNA SOLUCION ACUOSA QUE CONTIENE ACROLEINA; (B) LA ELIMINACION DE UNA PARTE IMPORTANTE DE LA SOLUCION ACUOSA DE DICHA MEZCLA DEL PRODUCTO DE REACCION; (C) LA ADICION DE UNA CANTIDAD SUFICIENTE DE UNA BASE A LA SOLUCION ACUOSA PARA FORMAR UNA SOLUCION BASICA QUE TIENE UN PH SUPERIOR A 7,5 Y EL MANTENIMIENTO DE LA SOLUCION BASICA DURANTE UN TIEMPO EFECTIVO PARA DISMINUIR EL CONTENIDO DE ACROLEINA DE LA MISMA; (D) OPCIONALMENTE, LA DILUCION DE LA SOLUCION BASICA CON AGUA Y (E)OPCIONALMENTE, EL TRATAMIENTO BIOLOGICO DE LA SOLUCION BASICA DILUIDA. EL PROCEDIMIENTO DE LA INVENCION PROPORCIONA UNA CORRIENTE CON EL SUBPRODUCTO POLIESTER QUE CONTIENE NIVELES REDUCIDOS DE ACROLEINA.
