Tris ( tribromophenoxy ) cyanurate is a nitrogen , bromine flame retardant excellent performance , widely used thermoplastic , ABS and rubber , a thermosetting resin can also be used . Thesis phenol and bromine , cyanuric chloride as raw materials , intermediate products were synthesized 2,4,6 - tribromo phenol and the target product tris ( tribromophenoxy ) cyanurate . And a variety of factors influence the reaction such as reaction temperature, reaction time , material and other process parameters were compared by orthogonal experiment has achieved optimum reaction conditions . Experiments show that : phenol and bromine molar ratio of 1:1.55 , bromine when the system temperature is dropping 35 ℃, the reaction temperature is 55 ℃, reaction time was 1h under the conditions of higher quality intermediates 2,4,6 - tribromo phenol ; 2,4,6 - tribromo phenol and cyanuric chloride molar ratio of 3.10:1 , sodium hydroxide added to the system when the temperature is 50 ℃, ethyl acetate ester 36g, the reaction temperature is 70 ℃, reaction time 1.5h under the conditions of a high quality final product three ( tribromophenoxy ) cyanuric acid esters. Especially in the synthesis of three ( tribromophenoxy ) cyanuric acid ester obtained white product. The synthesized compounds by infrared spectroscopy (IR), nuclear magnetic resonance (NMR), melting point (MP), high performance liquid (HPLC), differential scanning (DSC), thermal gravimetric analysis (TGA) , etc. were characterized and purity analysis . Meanwhile, according to the results of experiments designed to target products for industrial production equipment and piping synthetic route layout.
