ABSTRACT:
2-(2,4-Dihydroxyphenyl)-4,6-bis(2,4-dimethylphenyl)-s-triazine is prepared by reacting cyanuric chloride with m-xylene at a temperature of 0.degree.-110.degree. C. in the presence of a Lewis acid and at least one inert chlorinated aromatic solvent to give the intermediate 2-chloro-4,6-bis(2,4-dimethylphenyl)-s-triazine.
