Title (EN) METHOD OF MAKING HYDROXYMETHYLPHOSPHONATE, POLYURETHANE FOAM-FORMING COMPOSITIONS POLYURETHANE FOAM AND ARTICLES MADE THEREFORM
(FR) MÉTHODE DE FABRICATION DE PHOSPHONATE D'HYDROXYMÉTHYLE, COMPOSITIONS DE POLYURÉTHANE MOUSSANTES, MOUSSE POLYURÉTHANE ET ARTICLES FABRIQUÉS À PARTIR DE LADITE MOUSSE
Abstract:
(EN) A method of making hydroxymethylphosphonate comprising heating paraformaldehyde in a solvent to a desired reaction temperature, wherein the solvent is present in at least an amount necessary to solvate or suspend the paraformaldehyde; adding at least one alkyl phosphite to the heated paraformaldehyde, to provide hydroxymethylphosphonate, the alkyl phosphite being added to the heated paraformaldehyde at a rate which will avoid or inhibit the production of a significant exotherm and resulting high/significant level of acid by-product(s), there being present in the reaction medium at least one hindered amine catalyst in which the nitrogen in the amine is directly bound to a secondary and/or tertiary carbon of an organic group; and, optionally, following the completion of the addition, heating the reaction mixture to an elevated temperature.
(FR) Méthode de fabrication de phosphonate d'hydroxyméthyle comprenant le chauffage de paraformaldéhyde dans un solvant jusqu'à une température de réaction recherchée, ledit solvant étant présent à une teneur au moins nécessaire pour solvater ou suspendre le paraformaldéhyde ; l'addition d'au moins un phosphite d'alkyle au paraformaldéhyde chauffé pour obtenir le phosphonate d'hydroxyméthyle, le phosphite d'alkyle étant ajouté au paraformaldéhyde chauffé à une vitesse évitant ou inhibant une réaction exothermique significative et une teneur résultante élevée ou significative de sous-produits acides, sachant qu'au moins un catalyseur de type amine encombrée dont l'azote de l'amine est directement lié à un carbone secondaire et/ou tertiaire d'un groupement organique est présent dans le milieu réactionnel ; et éventuellement, une fois l'addition terminée, le chauffage du mélange réactionnel jusqu'à une température supérieure à l'ambiante.
