Patent ID: 10351538

Abstract:
The present invention provides methods respectively for producing a 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)-1,3,5-triazine, both of which are improved in yield and quality. The methods according to the present invention are characterized in that a reaction of 2,4,6-tris(2,4-dihydroxy-3-methylphenyl)-1,3,5-triazine with an alkylating agent is carried out using a base in the presence of an alcohol or water, and are also characterized in that an ester compound is used as an additive in a reaction of cyanuric chloride with 2-methylresorcinol.
