Abstract

Le procédé faisant l'objet de l'invention, du type consistant à faire réagir du formaldéhyde avec un composé phosphoré et un produit azoté de condensation, dans un milieu aqueux et à température élevée, caractérisé en ce qu'on utilise à titre de composé phosphoré le trichlorure de phosphore, et en tant que produit azoté de condensation, un produit obtenu par réaction de l'épichlorhydrine avec l'ammoniaque à une température de 5 à 20 degrés C et dans un rapport en moles des réactifs de 1:5 à 1:15 respectivement, en traitant ensuite la masse réactionnelle par un hydroxyde de métal alcalin.The process which is the subject of the invention, of the type consisting in reacting formaldehyde with a phosphorus compound and a nitrogenous condensation product, in an aqueous medium and at elevated temperature, characterized in that one uses as compound phosphorus phosphorus trichloride, and as a nitrogen condensation product, a product obtained by reaction of epichlorohydrin with ammonia at a temperature of 5 to 20 degrees C and in a mole ratio of the reactants from 1: 5 to 1:15 respectively, then treating the reaction mass with an alkali metal hydroxide.
