| Abstract: | TS-1 zeolite for hydroxylation of phenol was synthesized using TPAOH template.Characterization with XRD and IR verified the MFI structure and presence of Ti atoms in the framework of the zeolite.The effects of reaction conditions in the hydrothermal process on the catalytic activity and selectivity of TS-1 were investigated.It was found that the best results of hydroxylation of phenol were obtained at conditions of 170 ℃, crystallization time of 24～72 hours, n (TPAOH)/ n (SiO 2)of 0 22～0 30, n (SiO 2)/ n (TiO 2)of 33,and n (H 2O) / n (SiO 2)of 35. |
