以3,3’,5,5’-四甲基联苯二酚(TMBP)和丙烯酰氯为原料合成了3,3’,5,5’-四甲基联苯-4,4’-二丙烯酸酯,探讨了原料配比、缚酸剂种类、反应时间、反应温度等因素对产物收率的影响,得出了最佳工艺条件:n(TMBP)∶n(丙烯酰氯)∶n(三乙胺)=1∶3.0∶3.0,先在0℃下反应1h,然后在室温下反应8h,经后处理得到了无色针状晶体,为目标产物,收率为77.1%。并用红外和核磁等方法对产物结构进行了表征。 3,3 ’, 5,5’-tetramethylbiphenyl-4,4’-bis (4,4’-biphenyl) -benzothiophene was synthesized from 3,3’, 5,5’-tetramethylbiphenol (TMBP) and acryloyl chloride Acrylate, the effects of the ratio of raw materials, the kinds of acid-binding agents, the reaction time and the reaction temperature on the yield of the product were discussed. The optimum technological conditions were obtained as follows: n (TMBP) Ethylamine) = 1: 3.0: 3.0. The reaction was carried out at 0 ° C for 1 h and then at room temperature for 8 h. The colorless crystals were obtained after work-up, yielding 77.1%. The structure of the product was characterized by IR and NMR.
