Chloride → 2,4,6-Tris(2,3,4-tribromophenoxy)-1,3,5-triazine

Participants

Reaction Steps

An exemplary production process according to this invention comprises preparing an aqueous tribromophenolate solution and dripping this aqueous solution to a dispersion or solution of cyanuric chloride and tertiary amine in a non-hydrophilic solvent or adding said tertiary amine and a powder of cyanuric chloride to said aqueous solution. The preferred molar ratio of cyanuric chloride to tribromophenol is 1:2.94-3.60. Where both a tertiary amine and a phase transfer catalyst are employed, an exemplary procedure comprises preparing an aqueous tribromophenolate solution, adding a tertiary amine thereto and dripping the mixture to a solution or dispersion of cyarnuric chloride and phase transfer catalyst in a non-hydrophilic solvent or adding said phase transfer catalyst, said tertiary amine and a powder of cyanuric chloride to the aqueous tribromophenolate solution. After the above dripping or addition, the reaction system is aged where necessary and the non-hydrophilic solvent is removed from the reaction system at atmospheric or subatmospheric pressure. In this manner, tris(tribromophenoxy)-s-triazine of high purity can be obtained.
