摘　　要：通过三溴苯酚在醇钠的作用下与环氧氯丙烷反应生成三溴苯基环氧丙基醚,三溴苯基环氧丙基醚再与四氯化硅反应生成中间产物三溴苯氧基氯丙氧基三氯化硅,其再与环氧氯丙烷进一步反应,生成具有硅、氯、溴三元素协同阻燃的高效阻燃剂。探讨了反应温度、时间及物质的量比等对产率的影响,得到最适宜的工艺条件:三溴苯基环氧丙基醚与四氯化硅及环氧氯丙烷物质的量比为1:1:3.5,90℃反应8 h,其产率达98.2%。并采用FTIR、1H-NMR、极限氧指数等方法表征了产品的分子结构及阻燃性能等。Tribromophenol was reacted with epichlorohydrin to generate tribromophenyl epoxy propyl ether under the action of sodium alkoxide, then tribromophenyl epoxy propyl ether was reacted with silicon tetrachloride to generate intermediate tribromophenoxy chloropropoxy silicon trichloride, the intermediate product was further reacted with epichlorohydrin, synthesized an synergistic efficient flame retardants which having three elements of silicon, chlorine, bromine. The effect of reaction temperature, time and amount ratio of substance on the reaction yield was discussed. The optimal conditions for preparation were selected as follows： the ratio of the amount of substance between tribromophenyl epoxy propyl ether, silicon tetrachloride and epichlorohydrin is 1：1：3.5, reaction time is 8 h at 90℃. The percentage of the reaction yield can reach to 98.2%. The molecular structures of the product and its flame retardant properties were characterized by means of FTIR, 1H-NMR and OI technique.
