Abstract

L'invention concerne un procédé pour la préparation de mélanges de composés polyhydroxylés de bas poids moléculaire ainsi éventuellement que d'hydroxyaldéhydes et d'hydroxycétones par condensation de l'hydrate de formaldéhyde, de composés métalliques comme catalyseurs, ainsi que 0 à 10 % en poids, par rapport au formaldéhyde, de co-catalyseurs à base de composés transformables en la forme ènediol. Selon l'invention, on condense le formaldéhyde à une température de réaction de 10 à 150 degrés C en présence I dun composé soluble ou insoluble d'un métal des premier à huitième sous-groupes ou des deuxième à quatrième groupes principaux de la périodiques des élements, éventuellement fixé sur des supports de poids moléculaire élevé, et II de plus de 10 % en poids, par rapport au formaldéhyde, d'un ou plusieurs mono- ou polyalcools de bas poids moléculaire et/ou de composés polyhydroxylés de poids moléculaire élevé; on arrête la réaction à une teneur résiduelle en formaldéhyde de 0 à 10 % en poids par désactivation du catalyseur de manière connue, on élimine le catalyseur et éventuellement on réduit les groupes aldéhydiques et cétoniques présents dans le produit de réaction en groupes hydroxy. Applications: préparation de matières plastiques de polyuréthannes.
