Abstract

There is described a process for the preparation of 2-(2-4-dihydroxyphenyl)-4,6-bis(2,4-dimethylphenyl)-s-triazine of the formula I, which comprises (a) reacting cyanuric chloride of the formula II, in the presence of a Lewis acid in a ratio of 2.3 to 3.0 ml of Lewis acid per mole of cyanuric chloride employed in the presence of at least one inert chlorinated aromatic solvent, with 1,3-xylene of the formula III, in a ratio of 2.1 to 2.5 mol of compound of the formula III per mole of cyanuric chloride employed with addition of compound of the formula III in two steps, wherein the addition of 0.5 to 1.1 mol of the compound of the formula III takes place at 60 to 110 DEG C in the course of 2 to 12 hours, then the mixture is cooled to 20 to 50 DEG C in the course of 0 to 3 hours, after which the additional of 2.0 to 1.0 mol of the compound of the formula III takes place in the temperature range from 20 to 50 DEG C in the course of 5 to 15 hours to give the compound of the formula IV and then, (b) without isolating the compound of the formula IV obtained reacting this with resorcinol in a ratio of 0.5 to 1.0 mol of resorcinol per mole of cyanuric chloride employed at a temperature from 0 to 100 DEG C to give the compound of the formula I.
