Title

(EN) PROCESS FOR HYDROXYMETHYLATION

(FR) PROCEDE POUR L'HYDROXYMETHYLATION

Abstract

(EN) A general method for producing methylol compounds by the reaction of an organometallic compound with formaldehyde in which the formaldehyde is generated $i(in situ) from and by the use of a high molecular weight linear formaldehyde homopolymer.

(FR) On décrit, avec des exemples, une méthode générale pour la production de composés de méthylol par la réaction d'un composé organométallique avec du formaldéhyde, dans laquelle l'on produit le formaldéhyde $i(in situ) et grâce à l'utilisation d'un homopolymère linéaire à poids moléculaire élevé.
