    摘要: A process for producing tris(tribromophenoxy)-s-triazine. The process is characterized in that cyanuric chloride and an aqueous tribromophenolate solution are subjected to reaction in the presence of a tertiary amine. According to this process, the reaction goes to completion in a short time and the yield and purity of the product are high.

    摘要: This invention relates to a process for producing tris(tribromophenoxy)-s-triazine. This process is characterized by causing an aqueous tribromophenolate solution of not less than 50 weight % concentration containing a reducing agent to react on cyanuric chloride in the presence of a phase transfer catalyst. The process of this invention provides for a high output per unit reactor capacity. The yield and purity of the product are also high.
