The TS 1/diatomite catalyst was prepared for the hydroxylation of phenol with H2O2 in a fixed bed reactor and the effect of pretreatment on the properties of TS 1/diatomite were studied with FT IR, XRD, UV Vis, ICP AES and NH3 TPD techniques.

• 以固定床催化苯酚羟基化制苯二酚为目标反应,制备了负载型TS-1/硅藻土催化剂。 运用FT-IR、XRD、UV-Vis、ICP-AES和NH3-TPD等表征手段,研究了预处理介质对TS-1/硅藻土催化剂物化和催化性能的影响。
