摘　　要：以三溴苯酚、四氯化硅及2,3-二溴丙醇为主要原料合成新型阻燃剂2,3-二溴丙氧基-三(三溴苯氧基)硅烷。探讨了加料顺序、溶剂、反应温度、反应时间及物质的量比等对产率的影响,并采用FTIR、1H-NMR和极限氧指数对产品的分子结构及性能进行了表征。该产品为硅、溴协同高效阻燃剂,实验表明:其热稳定性好,应用于聚氯乙烯等材料有良好的阻燃、增塑和成炭防熔融滴落效果。A novel type - 2,3 - dibromopropoxy-tris （tribromophenoxy） silane was synthesized by tribromophenol, silicon tetrachloride and 2,3 - dibromo propanol. The effect of charging order, solvent, reaction temperature, reaction time and amount ratio of substance on the reaction yield was also discussed. The molecular structures and properties of the product were characterized by means of FTIR, ~ H-NMR and LOI technique. The product was an efficient synergistic flame retardants with two elements of silicon and bromine. Experiments showed that the product thermal stability was well. The product used in PVC and other materials had a good effect on antiflaming, plasticizing ,charring and anti-dripping.
