研究了Keggin磷钨酸（PTA）包覆金属有机骨架MIL-100（Fe或Cr）和MIL-101（Fe或Cr）催化苯酚和甲醛羟烷基化合成双酚F的反应。制备了具有不同β值（W/M摩尔比，其中M = Fe或Cr）的PTA @ MIL-100（Fe或Cr）（β）和PTA@MIL-101（Fe或Cr）（β），并通过XRD、BET、FT-IR、TG、SEM、TEM和ICP进行表征。研究结果表明，PTA@MIL-100（Fe或Cr）（β）比PTA@MIL-101（Fe或Cr）（β）具有更高的催化活性。PTA@MIL-100（Fe）（0.4）是所研究的催化剂中最有效的，并且具有优异的重复使用性。在PTA@MIL-100（Fe）（0.40）催化剂上，双酚F的收率和选择性分别为92.12%和93.01%。考察了反应时间、反应温度、催化剂浓度、苯酚/甲醛摩尔比对反应性能的影响。提出了苯酚与甲醛羟烷基化合成双酚F的可能机理。
Hydroxyalkylation of phenol with formaldehyde to bisphenol F was investigated over the metal-organic frameworks of MIL-100(Fe or Cr) and MIL-101(Fe or Cr) encapsulated with Keggin phosphotungstic acid (PTA). PTA@MIL-100(Fe or Cr) (beta) and PTA@MIL-101 (Fe or Cr) (beta) with different beta values (the molar ratio of W/M, where M = Fe or Cr) were prepared and characterized by XRD, BET, FT-IR, TG, SEM, TEM, and ICP. The research results showed that PTA@MIL-100(Fe or Cr)(beta) had a higher catalytic activity than PTA@MIL-101(Fe or Cr)(beta). PTA@MIL-100(Fe)(0.4) was the most effective among the studied catalysts and had excellent reusability. A 92.12% product yield and 93.01% selectivity for bisphenol F could be obtained over the PTA@MIL-100(Fe)(0.40) catalyst. The effects of the reaction time, reaction temperature, catalyst concentration, and phenol/formaldehyde molar ratio on the reaction performance were also investigated. A plausible mechanism for hydroxyalkylation of phenol with formaldehyde to bisphenol F was proposed.
