摘　　要：双酚F作为一种重要的新型化工原料,被广泛用于低黏度环氧树脂、聚酯和聚碳酸酯树脂等材料的合成。然而,在苯酚/甲醛比例较低的情况下,传统的液态质子酸催化剂催化缩合反应生成双酚F的选择性和产率较低,并且存在设备腐蚀及废酸处理困难等问题,这严重限制了双酚F的进一步应用。本研究探讨了MIL-101(Fe)-SO_(3)H非均相催化剂的合成与表征,采用了高效液相色谱法测定了该催化剂催化合成双酚F的反应活性,并在不同的温度下对催化产率和选择性进行了测试。其中,MIL-101(Fe)-SO_(3)H-0.3在苯酚/甲醛5:1的低配比条件下,就能以高的产率(88.4%)和选择性(93.6%)催化合成双酚F。Bisphenol F,an essential emerging chemical intermediate,is extensively utilized in the production of low-viscosity epoxy resins,polyesters,and polycarbonate resins.However,the traditional liquid protonic acid catalysts for the condensation reaction to synthesize Bisphenol F exhibit diminished selectivity and yield at a reduced phenol-to-formaldehyde ratio,accompanied by issues such as equipment corrosion and the complexity of waste acid management,which significantly impede the broader application of Bisphenol F.The present investigation delves into the synthesis and characterization of the MIL-101(Fe)-SO_(3)H heterogeneous catalyst,employing high-performance liquid chromatography to ascertain the catalytic activity for Bisphenol F synthesis.The yield and selectivity of the catalysis were evaluated under various temperatures.Notably,the catalyst MIL-101(Fe)-SO_(3)H-0.3,even at a low phenol/formaldehyde ratio of 5:1,facilitates the synthesis of Bisphenol F with remarkable efficiency,achieving a yield of 88.4% and a selectivity of 93.6%.
