METHODS FOR MODIFYING 1,3,5-TRIAZINE DERIVATIVES

摘要

A method for modifying 1,3,5-triazine derivatives characterized by reacting a 1,3,5-triazine derivative having at least one amino or monosubstituted amino group on any of the ring carbon atoms with an alcohol by heating in the presence of a metallic catalyst and hydrogen to thereby introduce an alkyl or alkenyl group into each amino or monosubstituted amino group; another method for modifying 1,3,5-triazine derivatives characterized by reacting a 1,3,5-triazine derivative having at least one amino or monosubstituted amino group on any of the ring carbon atoms with a dihydric alcohol by heating in the presence of a metallic catalyst and hydrogen to thereby introduce a hydroxylated alkyl group into each amino or monosubstituted amino group; and 1,3,5-triazine derivatives obtained by the methods. The various modified substituted 1,3,5-triazine derivatives thus produced are generally obtained as a mixture. These derivatives can be isolated as high-purity compounds by a general separation method for organic compounds, and the compounds are usable in the various applications mentioned in the specification. According to applications (for example, use as modifier additives, in particular a flame-retardant and a plasticizer for resins), the reaction mixture can be used as it is without being separated. Many of the substituted triazine derivatives obtained have been relatively difficult to synthesize or expensive. Since many of the derivatives are interesting with respect to their physical properties, e.g., solubility in water and in various organic solvents, high-temp. stability, melting point, boiling point, and basicity, they are thought to have a wider range of applications than conventional ones.
