[0026] a PPh 2 -The preparation method of ordered mesoporous polymer-Pd (II) heterogeneous catalyst, comprises the following steps:
[0027] 1) At a temperature of 308K, mix 1.10g of phenol (Phenol), 20% aqueous sodium hydroxide solution and p-PPh 2 -Phenol, 37% formaldehyde solution was stirred and mixed, and then reacted at 340K for 2h to obtain 2 Polymers with functional groups (PPh 2 -MPs) prepolymer, which is subsequently formulated into PPh with a mass ratio of 20% 2 - MPs prepolymer ethanol solution.
[0028] 2) PPh obtained in step 1 2 -Add 0.90g of triblock copolymer Pluronic F127 (EO106PO70EO106, M w =12,600, Acros Chemical Inc.), 20.0g ethanol solution, after standing at room temperature for 5h, further solidified at 373K temperature, 48w%H 2 SO 4 Extraction, the obtained dark brown solid is PPh 2 Ordered mesoporous polymer materials with functional groups (PPh 2 -MPs).
[0029] 3) Add 0.50g of PdCl 2 (PPh 3 ) 2 The homogeneous catalyst was dissolved in...
