四(4-溴苯基)乙烯的合成

Synthesis of Tetra(4-bromophenyl) ethylene

以四苯基乙烯为原料,在一定的条件下与溴水反应,生成四(4-溴苯基)乙烯.经过对比分析:反应物四苯基乙烯与溴水的物料比为1∶10且反应时间达到16 h时,反应的产率最高.同时,通过傅里叶红外光谱(FTIR)、核磁共振光谱(NMR)等检测手段对产物的性能和结构进行表征.

Tetraphenyl ethylene as raw material,reacted with bromine water to generate tetra （4-bromophenyl） ethylene.By comparison and analysis：reactant tetraphenyl ethylene with bromine water ratio of material for 1∶.10 and the reaction time to 16 h,the reaction rate reached the highest.At the same time,the performance and structure of the products were characterized by means of Fourier infrared spectroscopy （FT-IR） , Nuclear magnetic resonance spectra（ NMR） and other methods.
