Abstract

L'invention concerne un procédé de préparation de mélanges de composés polyhydroxylés de bas poids moléculaire, et éventuellement d'hydroxyaldéhydes et d'hydroxycétones, par condensation du formaldéhyde en présence de composés du plomb II, comme catalyseurs, et de cocatalyseurs consistant en un mélange d'hydroxyaldéhydes et d'hydroxycétones. On effectue la condensation de solutions de formaline, aqueuses, contenant de 20 à 65 % en poids de formaldéhyde et/ou de dispersions de paraformaldéhyde, en présence : a. De sels solubles ou insolubles de plomb Il ou d'un support de haut poids moléculaire portant du plomb II lié; et b. D'un cocatalyseur, constitué d'un mélange d'hydroxyaldéhydes et d'hydroxycétones. Les composés obtenus sont utiles notamment dans la fabrication des polyuréthannes comme antigel, etc
