Abstract

a. Procédé pour la fabrication de 2,4-dioxohexahydro-1,3,5-triazine. b. Procédé caractérisé en ce qu'on fait réagir des composés du formol tels que de la méthylène-diurée ou la diméthylol-urée, ou des produits de condensation urée-formol solides, ou des mélanges d'urée et de paraformaldéhyde, ou l'hexaméthylènetétramine, ou les résidus restant après évaporation de solutions d'urée-formol, en présence d'une quantité d'urée telle que dans le mélange de reaction, les rapports molaires entre le formol et l'urée se situent entre 1 : 2,1 et 1 : 4,5, la réaction étant réaliser en continu ou en discontinu, à des températures de 100 à 300 degrés C. c. Procédé applicable à la fabrication de produits bactéricides et fongicides.at. Process for the manufacture of 2,4-dioxohexahydro-1,3,5-triazine. b. Process characterized by reacting formaldehyde compounds such as methylene diurea or dimethylol urea, or solid urea-formaldehyde condensation products, or mixtures of urea and paraformaldehyde, or hexamethylenetetramine , or the residues remaining after evaporation of urea-formalin solutions, in the presence of a quantity of urea such that in the reaction mixture the molar ratios between formalin and urea are between 1: 2.1 and 1: 4.5, the reaction being carried out continuously or batchwise, at temperatures of 100 to 300 degrees C. c. Process applicable to the manufacture of bactericidal and fungicidal products.
