Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA DEPURAR UNA COMPOSICION DE 1,3 - PROPANODIOL QUE CONTIENE CARBONILO. EL PROCEDIMIENTO CONSISTE EN A) FORMAR UNA SOLUCION DE DICHA COMPOSICION DE 1,3 PROPANODIOL EN UN MEDIO ACUOSO ACIDO, B) AÑADIR UNA CANTIDAD SUFICIENTE DE UNA BASE AL MEDIO ACUOSO PARA FORMAR UNA SOLUCION BASICA QUE TENGA UN PH MAYOR QUE 7; C) CALENTAR LA SOLUCION BASICA EN CONDICIONES EFECTIVAS PARA DESTILAR UNA PARTE PRINCIPAL DEL AGUA; Y D) CALENTAR LA SOLUCION BASICA RESTANTE EN CONDICIONES EFECTIVAS PARA DESTILAR UNA PARTE PRINCIPAL DEL PDO Y OBTENER UNA COMPOSICION DE 1,3 - PROPANODIOL QUE TENGA UN CONTENIDO DE CARBONILO INFERIOR A LA COMPOSICION INICIAL DE 1,3 PROPANODIOL QUE CONTIENE CARBONILO. EL PROCEDIMIENTO DE LA INVENCION PREVE UN 1,3 - PROPANODIOL DEPURADO QUE SE PUEDE USAR COMO MATERIA PRIMA PARA UN POLIESTER LIGERAMENTE COLOREADO.
