以改进方法合成的BZSM5分子筛为母体,采用气固相法合成了TiZSM5分子筛,并以XRD,FTIR,UVVis,XRF,SEM,ICPAES和MASNMR等手段对BZSM5和TiZSM5进行了表征,考察了TiZSM5对苯酚羟基化反应的催化性能.结果表明,合成BZSM5时的前期低温晶化有助于晶粒的减小;以其为母体制备的TiZSM5对苯酚羟基化反应具有优异的催化性能.在n(PhOH)/n(H2O2)=3,n(Me2CO)/n(PhOH)=2.7,m(cat)/m(PhOH)=5%,T=353K和t=6h的反应条件下,苯酚转化率可达20%以上. TiZSM5 zeolites were synthesized by gas-solid phase synthesis using BZSM5 molecular sieves modified by gas-solid method. The properties of BZSM5 and TiZSM5 were characterized by XRD, FTIR, UVVis, XRF, SEM, ICPAES and MAS NMR. Hydroxylation.The results show that the pre-low-temperature crystallization of BZSM5 contributes to the decrease of the grain size.The TiZSM5 prepared by using it as a precursor has excellent catalytic activity for the hydroxylation of phenol.At the n (PhOH) /n(H2O2)=3,n(Me2CO)/n(PhOH)=2.7,m(cat)/m(PhOH)=5%,T=353K and t = 6h, the conversion of phenol is up to More than 20%.
