Title
(DE) ZWEI-STUFIGES VERFAHREN ZUR HERSTELLUNG VON POLYESTEROLEN
(EN) TWO-STEP METHOD FOR PRODUCING POLYESTEROLS
(FR) PROCEDE EN DEUX ETAPES POUR PRODUIRE DES POLYESTEROLS
Abstract
(DE)
Die vorliegende Erfindung betrifft ein zwei-stufiges Verfahren zur Herstellung von PoIyesterolen mit den folgenden Verfahrensschritten: a) Herstellung mindestens eines Basis-Polyesterols durch die Umsetzung von jeweils mindestens einer Dicarbonsäure mit jeweils mindestens einer Polyhydroxylverbindung, b) Umsetzung des Basis-Polyesterols aus a) oder einer Mischung aus den Basis-Polyesterolen aus a) mit mindestens einem Enzym und gegebenenfalls zusätzlich mit Polyhydroxylverbindungen. Die Erfindung betrifft weiterhin ein Polyesterol, das nach dem obigen Verfahren herstellbar ist.
(EN)
The invention relates to a two-step method for producing polyesterols, comprising the following steps: a) production of at least one base polyesterol by reacting at least one dicarboxylic acid with at least one polyhydroxyl compound, b) reaction of the base polyesterol from step a) or a mixture of the base polyesterols from step a) with at least one enzyme and optionally also polyhydroxyl compounds. The invention also relates to a polyesterol that is produced according to said method.
(FR)
L'invention concerne un procédé en deux étapes pour produire des polyestérols, comprenant les étapes suivantes : a) production d'au moins un polyestérol de base par la transformation d'au moins un acide dicarboxylique avec au moins un composé de polyhydroxyle ; b) transformation du polyestérol de base obtenu en a) ou d'un mélange de polyestérols de base obtenus en a) avec au moins une enzyme et éventuellement avec des composés de polyhydroxyle. L'invention concerne également un polyestérol, qui peut être produit selon le procédé susmentionné.
