A method for alkylation of at least one or more amino groups or mono-substituted amino groups, each on a carbon atom of a triazine ring of 1,3,5-triazine derivatives (melamine, melamine derivatives and various kinds of guanamine derivatives and the like), which includes reacting the 1,3,5-triazine derivatives having at least one or more amino groups or mono-substituted amino groups with alcohols in the presence of a catalyst of a metal of group VII and/or group VIII in the periodic table. The object of the invention is to provide a method for alkylation of 1,3,5-triazine derivatives, which includes alkylating amino groups or mono-substituted amino groups in carbon atoms of a 1,3,5-triazine ring, whereby substituted 1,3,5-triazine derivatives which are a group of useful compounds and which are widely used as intermediates of fine chemicals such as agricultural chemicals, medications, dye-stuffs, paints and the like, as resin materials and as flame-retardant materials can be easily produced in high yields.
一种用于烷基化1,3,5-三嗪衍生物(三聚氰胺、三聚氰胺衍生物、各种脲衍生物等)中至少一个或多个氨基或单取代氨基的碳原子的方法,包括在周期表中的第VII和/或第VIII族金属催化剂的存在下,将具有至少一个或多个氨基或单取代氨基的1,3,5-三嗪衍生物与醇反应。该发明的目的是提供一种烷基化1,3,5-三嗪衍生物的方法,其中包括在1,3,5-三嗪环的碳原子上烷基化氨基或单取代氨基,从而可以高产地轻松制备出取代的1,3,5-三嗪衍生物,这些衍生物是一类有用的化合物,广泛用于农药、药物、染料、涂料等精细化学品的中间体,以及树脂材料和阻燃材料。
