    • The present invention provides a method for modifying melamine derivatives that can produce N-substituted melamine derivatives by introducing a substituent group to melamine or N-substituted melamine derivatives. The method is characterized by heating melamine or an N-substituted melamine derivative and an alcohol in the presence of a mixed catalyst comprising a hydrogenation catalyst and a dehydrogenation catalyst and hydrogen to allow reaction or heating melamine or an N-substituted melamine derivative and an alcohol in the presence of a hydrogenation catalyst and hydrogen with addition/coexistence of a metal to allow reaction. The compound groups obtained by introducing a substituent group to the amino group of melamine derivative with an alcohol by the method of the present invention can be used widely as intermediates of fine chemicals such as various agricultural chemicals, medicines, dyes, paints, etc. and as various resin materials and flame retardant materials.
    • 本发明提供了一种通过将取代基引入三聚氰胺或N-取代的三聚氰胺衍生物来修饰可以产生N-取代的三聚氰胺衍生物的三聚氰胺衍生物的方法。 该方法的特征在于在包含氢化催化剂和脱氢催化剂和氢气的混合催化剂存在下加热三聚氰胺或N-取代的三聚氰胺衍生物和醇,以允许反应或加热三聚氰胺或N-取代的三聚氰胺衍生物和醇 在氢化催化剂和氢气的存在下,加入/共存金属以允许反应。 通过本发明的方法,通过用醇将三聚氰胺衍生物的氨基引入取代基而获得的化合物基团可广泛用作各种农药,药物,染料,油漆等精细化学品的中间体,以及 作为各种树脂材料和阻燃材料。
