PCT No. PCT/JP95/00881 Sec. 371 Date Feb. 7, 1997 Sec. 102(e) Date Feb. 7, 1997 PCT Filed May 9, 1995 PCT Pub. No. WO95/30662 PCT Pub. Date Nov. 16, 1995The 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.
