Abstract:
A method of alkylation of 1,3,5-triazine compounds comprising reacting a 1,3,5-triazine compound of the formula (I) having at least one or more amino groups or mono-substituted amino groups on a carbon atom of the ring in the presence of a catalyst of a metal of group VIII in the periodic table and a hydrogen-containing gas to alkylate at least one or more amino groups or mono-substituted amino groups ##STR6## wherein at least one of X.sup.1, X.sup.2 and X.sup.3 independently represents NHR.sup.1 in which R.sup.1 represents a hydrogen atom or a C.sub.1-20 alkyl group that is optionally substituted with a hydroxyl group, a C.sub.1-6 alkoxy group or a phenyl group,X.sup.1, X.sup.2 and X.sup.3 which are not NHR.sup.1 independently represent NR.sup.2 R.sup.3 in which R.sup.2 and R.sup.3 independently represent a C.sub.1-20 alkyl group wherein said alkyl group is optionally substituted with a hydroxyl group, a C.sub.1-6 alkoxy group or phenyl group,R.sup.2 and R.sup.3 may together form --(CH.sub.2).sub.2-5 --, CH.sub.2 CH.sub.2 --(C.sub.1-8 alkyl)N--CH.sub.2 CH.sub.2 -- or CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 -- in which an alkylene chain is desirably substituted with one or two C.sub.1-8 alkyl groups),a C.sub.1-20 alkyl group, a phenyl group or a C.sub.1-10 alkoxy group, with aldehydes or ketones of the formula (II) ##STR7## wherein R.sup.4 and R.sup.5 independently represent a hydrogen atom or a C.sub.1-20 alkyl group that is optionally substituted with a hydroxyl group, a C.sub.1-6 alkoxy group or a phenyl group, orR.sup.2 and R.sup.3 may together form an alkylene group: --(CH.sub.2).sub.3-5 --.
