Abstract

Un procedimiento para hidrogenar un oligómero de poliéster que contiene residuos de ácido tereftálico en donde los residuos de ácido tereftálico se convierten en residuos de ácido 1,4-ciclohexanodicarboxílico. El procedimiento comprende poner en contacto dicho oligómero de poliéster con hidrógeno en presencia de un catalizador de hidrogenación soportado o suspendido bajo una presión de hidrógeno de por lo menos 60 bares manométricos (barg) y a una temperatura de aproximadamente 180 a 280°C por lo que al menos un mol por ciento de los residuos de ácido tereftálico se convierte en residuos de ácido 1,4-ciclohexanodicarboxílico. También se da a conocer un procedimiento para la preparación de poliésteres que contienen residuos de ácido 1,4-ciclohexanodicarboxílico hidrogenando primero un oligómero de poliéster que contiene residuos de ácido tereftálico y luego haciendo reaccionar el oligómero resultante con uno o más reactivos formadores de poliéster para producir un poliéster de peso molecular superior.
