文章以苯胺,溴素,苯基硫代膦酰二氯等为原料,合成了P,N,S,Br四元素协同阻燃的新型高效阻燃剂苯基硫代膦酰二(2,4,6-三溴苯基)胺,最佳工艺条件为以二甲苯做溶剂,吡啶做缚酸剂,低水合硼酸锌作催化剂,苯基硫代膦酰二氯与2,4,6-三溴苯胺的摩尔比为1∶2.1,回流反应12 h,产率可达81.21%。并通过IR和NMR对产品的结构进行了表征。 In this paper, aniline, bromine, phenylthiophosphoryl dichloride and other raw materials, the synthesis of P, N, S, Br synergistic flame retardant synergistic new flame retardant phenylthiophosphoryl bis , 6-tribromophenyl) amine. The optimum conditions are xylene as solvent, pyridine as acid-binding agent and low-hydrated zinc borate as catalyst, and phenylthiophosphoryl chloride and 2,4,6-tris Bromine aniline molar ratio of 1: 2.1, refluxing reaction 12 h, the yield of up to 81.21%. The structure of the product was characterized by IR and NMR.
