2. 4, 6 - three (2, 4, 6 - three-bromophenylacetic oxy) - 1, 3, 5 - triazine synthesis method

The invention discloses a synthesis method of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine. The method includes the steps that N-methylimidazole and 2,4,6-tribromophenol form salt when a solvent exists or no solvent exists, then, N-methylimidazole and 2,4,6-tribromophenol react with tricyanogen chloride, and the 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine is obtained. According to the synthesis method, inorganic base is not needed, no waste water with inorganic base is generated, and the method is an atom-economical and pollution-free method for preparing the 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine.

PRODUCTION OF TRIS (2,4,6-TRIBROMOPHENOXY-1,3,5-TRIAZINE)

Tris(2,4,6-tribromophenoxy)-1,3,5-triazine , an effective flame retardant, is prepared by an efficient, low cost process. The process comprises (A) forming a mixture from 2,4,6- tribromophenol, alkali metal carbonate, and acetone as the solvent, refluxing the mixture to form a first reaction product mixture, (B) feeding cyanuric chloride portionwise to first reaction product mixture and refluxing the resultant mixture to form a solids-containing second reaction product mixture; C) recovering solids from second reaction product mixture, washing the solids with acetone and then with hot water, and thereafter drying the washed product.
