Description
Estabilización de polioles
5 La invención se refiere al uso de mezclas que contienen polioles en un procedimiento para la preparación de poliésteres.
Los polioles, tales como en particular compuestos de di-, tri- o tetrahidroxilo, tienen gran importancia debido a sus múltiples posibilidades de uso en la técnica. Se consideran estables frente a la oxidación en condiciones normales y 10 se almacenan por tanto normalmente en aire.
Si se usan polialcoholes de este tipo ahora para reacciones secundarias, en las que por ejemplo con el objetivo de la formación de ésteres se generan condiciones ácidas, entonces se producen descoloraciones con frecuencia a pesar normalmente de la alta pureza del poliol usado, que hace que el producto secuencial sea inservible o invendible. El
15 documento EP0572256A2 da a conocer un procedimiento para la preparación de poliésteres, añadiéndose compuestos de organofósforo y un isocianato polifuncional para evitar las descoloraciones.
Existe por tanto la necesidad de proporcionar un procedimiento que reduzca tales descoloraciones indeseadas.
20 Se encontró ahora que mediante el uso de mezclas que contienen polioles, que portan al menos dos, preferentemente dos, tres o cuatro grupos hidroxilo, de los cuales a menos uno, preferentemente todos están unidos a respectivamente un átomo de carbono alifático, y al menos uno o varios compuestos de fórmula (I) o (II)
en los que 25 n representa 1, 2, 3 o 4, preferentemente representa 2 o 3 m representa 1, 2 o 3, preferentemente representa 1 o 2 30 p representa 2 Q representa azufre o alquileno C1-C4, preferentemente representa alquileno C1-C4 y R1 respectivamente independientemente de otros restos R1 dado el caso existentes representa alquilo C1-C8 o 35 alcoxilo C1-C8, debiendo estar sustituida además al menos una posición orto de los dos anillos de fenilo de acuerdo con la fórmula
(II) o del anillo de fenilo de acuerdo con la fórmula (I) con un resto secundario o terciario, en un procedimiento para la preparación de poliésteres pueden reducirse las descoloraciones indeseadas.
40 Alquilo o alquileno o alcoxilo significa respectivamente independientemente un resto alquilo o alquileno o alcoxilo de cadena lineal, ramificado o no ramificado, eventualmente cíclico.
Alquilo C1-C8 representa por ejemplo metilo, etilo, n-propilo, iso-propilo, n-butilo, sec-butilo y terc-butilo, n-pentilo, 145 metilbutilo, 2-metilbutilo, 3-metilbutilo, neo-pentilo, 1-etilpropilo, ciclo-hexilo o 2-metilciclohexilo, preferentemente representa metilo, terc-butilo o ciclo-hexilo.
Alcoxilo C1-C8 representa por ejemplo metoxilo, etoxilo, n-propoxilo, iso-propoxilo, n-butoxilo, sec-butoxilo y tercbutoxilo, neo-pentoxilo, ciclo-hexoxilo, ciclo-pentoxilo y n-hexoxilo.
50 Alquileno C1-C4 representa por ejemplo metileno, etanodiílo, 1,2-propanodiílo, 1,3-propanodiílo, 1,4-butanodiílo, 2,3butanodiílo o 1,3-butanodiílo, preferentemente representa metileno.

La invención se explica en más detalle por medio de los ejemplos, sin embargo sin que ésta se limite a los mismos. 5 Ensayos:
Respectivamente se dispusieron 100 g de la mezcla que va a someterse a ensayo de 1,6-hexanodiol y estabilizador en un matraz de cuatro cuellos de 1 l y se calentaron por medio de un manto calefactor con agitación hasta 130 ºC 10 durante 4 h. A continuación se añadieron con conducción de nitrógeno constante 100 g de ácido adípico en la masa fundida producida, enfriándose ésta hasta aproximadamente de 80 ºC a 90 ºC. A continuación se calentó en el intervalo de 5 minutos hasta 175 ºC y se dejó reaccionar durante 10 minutos a esta temperatura. Se eliminó el vapor de agua producido durante la esterificación. Tras finalizar el tiempo de reacción se determinó el índice de color de la masa fundida a 130 ºC en una cubeta redonda de 11 mm. La calibración se realizó respectivamente frente a agua
15 (índice de color APHA 0) respectivamente directamente antes de la medición.
