Abstract

L'invehtion concerne un procédé pour la préparation d'un mélange de polyalcools et, éventuellement, d'hydroxyaldéhydes et d'hydroxycétones, de bas poids moléculaire, par condensation du formaldéhyde dans un milieu de réaction aqueux, en présence de composés métalliques comme catalyseurs, ainsi que de composés transformables en la forme énediol comme cocatalyseurs. Selon l'invention, on envoie des gaz de synthèse contenant du formaldéhyde à des températures de 10 à 150 degrés C en continu ou en discontinu dans un liquide absorbant qui contient : a. 5 à 99 % en poids d'eau, b. 0,1 à 90 % en poids de composés transformables en forme ènediol comme cocatalyseur, c. 0 à 20 % en poids de composés métalliques solubles ou insolubles, de préférence des composés de métaux des premier à huitième sous-groupes ou des deuxième à quatrième groupes principaux de la Classification Périodique des Eléments, qui sont éventuellement fixés sur des supports de poids moléculaire élevé, comme catalyseur, et d. 0 à 60 % en poids d'un ou plusieurs monoalcools ou, de préférence, polyalcools de bas poids moléculaire et/ou composés polyhydroxylés de poids moléculaire élevé.
