CA 2171730

A method of converting a toxic composition contianing an aldehyde to a composition which is subtantially non-toxic. The aldehyde is reacted with a polymer having protic oxygen or nitrogen atoms, a poluimine or polymine derivative, and an active aromatic to couple or react with the aldehyde-containing composition. Preferably, this aldehyde conversion process will yield a substantially fluid reaction product by way of a substantially irreversible reaction.

Procédé de conversion d'une composition toxique contenant un aldéhyde en une composition sensiblement non toxique. On fait réagir l'aldéhyde avec un polymère présentant de l'oxygène ou de l'azote protique, un polyimine ou l'un de ses dérivés et un composé aromatique actif pour le coupler ou le faire réagir avec la composition à base aldéhyde. Ce procédé de conversion de l'aldéhyde va donner de préférence un produit de réaction sensiblement fluide au cours d'une réaction quasiment irréversible.
