The object of the present invention is to provide a method for producing substituted-1,3,5-triazine derivatives at high yield, in which at least one of carbon atoms in the ring thereof is substituted by a secondary amine group having at leat one of alkyl groups.
The method of the present invention is a method for alkylation of 1,3,5-triazine derivatives, characterized by reacting 1,3,5-triazine derivatives (melamines, melamine derivatives, various kinds of guanaminde derivatives, etc.) which has at least one or more amino groups or mono-substituted amino groups on carbon atom of the ring thereof, with aldehydes or ketones alcohols in the presence of a catalyst of a metal of group VII and/or group VIII in the periodic table and a hydrogen-containing gas to alkylate said at least one of amino groups or mono-substituted amino groups.
These derivatives are widely used as intermediates of fine chemicals such as agricultural chemicals, medications, dyestuffs, paints and the like and are widely used resin materials and as flame-retardant materials.
本发明的目的是提供一种高产率生产取代的-1,3,5-三嗪衍生物的方法,在这种衍生物中,其环上至少有一个碳原子被至少有一个烷基的仲胺基取代。
本发明的方法是 1,3,5-三嗪衍生物的烷基化方法,其特征是将 1,3,5-三嗪衍生物(三聚氰胺、三聚氰胺衍生物、各种胍衍生物等)与至少具有一个或多个烷基的 1,3,5-三嗪衍生物(三聚氰胺、三聚氰胺衍生物、各种胍衍生物等)反应。其特征是:在元素周期表中第 VII 族和/或 VIII 族金属和含氢气体催化剂的存在下,将环的碳原子上至少有一个或多个氨基或单取代氨基的 1,3,5-三嗪衍生物(三聚氰胺、三聚氰胺衍生物、各种鸟苷酸衍生物等)与醛或酮醇反应,使上述至少一个氨基或单取代氨基烷基化。
这些衍生物被广泛用作精细化工产品的中间体,如农药、药物、染料、油漆等,也被广泛用作树脂材料和阻燃材料。
