    • 2,4-Diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine were prepared by the reaction of the corresponding methyl or ethyl .gamma.-tribromo-butyrate or methyl or ethyl .gamma.-trichlorobutyrate with biguanide. The N-methylol derivatives of the diaminotrihalopropyl triazines were prepared by the reaction of the triazines with aqueous formaldehyde. Two pure tetramethylol derivatives were prepared, namely: 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazine. The tetramethylol derivatives were used to impart durable flame retardancy and wrinkle recovery to cellulosic textiles, particularly to cotton. Flame-retardancy was also imparted to wool and to blends of cotton and polyester.
    • 2,4-二氨基-6(3,3,3-三溴-1-丙基)-1,3,5-三嗪和2,4-二氨基-6(3,3,3-三氯-1-丙基) - 通过相应的甲基或乙基γ-三溴丁酸酯或γ-三氯丁酸乙酯与双胍反应制备1,3,5-三嗪。 二氨基三卤代丙基三嗪的N-羟甲基衍生物通过三嗪与甲醛水溶液的反应来制备。 制备两种纯的四羟甲基衍生物,即2,4-双[双(羟甲基)氨基] -6-(3,3,3-三溴-1-丙基)-1,3,5-三氮杂和2,4 双[双(羟甲基)氨基] -6-(3,3,3-三氯-1-丙基)-1,3,5-三嗪。 使用四羟甲基衍生物赋予纤维素纺织品特别是棉花持久的阻燃性和皱纹恢复性。 还赋予了羊毛和棉和聚酯的混合物的阻燃性。
