2,4,6-tris (2-hydroxy-3-methyl-4-alkoxyphenyl) -1,3,5-triazine compound and 2,4,6-tris (2,4-dihydroxy-3-methylphenyl) ) Method for producing 1,3,5-triazine

摘要

The object of the present invention is to improve the yield and quality of 2,4,6-tris (2-hydroxy-3-methyl-4-alkoxyphenyl) -1,3,5-triazine compounds and 2,4 , 6-tris (2,4-dihydroxy-3-methylphenyl) -1,3,5-triazine is provided. In the method of the present invention, the reaction between 2,4,6-tris (2,4-dihydroxy-3-methylphenyl) -1,3,5-triazine and an alkylating agent is carried out using a base in the presence of alcohol or water. In addition, an ester compound is used as an additive in the reaction between cyanuric chloride and 2-methylresorcinol.
