In the process of laboratory study, oxycodone was prepared by oxidating thebaine at 6,14-position under oxydol, hydrodeoxidizing 7,8-position double bond and 14-position ether under palladium catalyst. Furthermore, N-methyl of oxycodone was isolated byα-chloro-ethyl chloroformate under anhydrous condition and protection of 14-position hydroxyl to obtain noroxycodone, which was further converted into methylnaltrexone by N-alkylation in presence of cyclopropyl bromomethane, then by isolating 3-position methyl of methylnaltrexone under boron tribromide, becoming hydrochloride to prepare target compound, natrexone hydrochloride.

SO〓〓/M〓O〓 solid superacid was applied to the photocatalytic oxidation of organic pollutants for the first time. Porous SO〓〓/TiO〓 solid superacid catalysts with high specific surface area were prepared by sol-gel method. The photocatalytic degradation of bromomethane was used as model reaction. The influence of impregnation with H〓SO〓 solution on the structure of catalysts and their photocatalytic performance was systematically studied by using X-ray diffraction, X-ray photoelectron spectroscopy, N〓 sorption analysis applying BET method, UV-Vis diffuse reflectance spectroscopy, FTIR spectroscopy, O〓-TPD and photocatalytic activity measurement. The acidity of TiO〓-based catalysts was investigated by Hammett indicator method, NH〓-TPD and IR spectra of pyridine adsorbtion. The mechanism of superacidifing effects on photocatalytic performances such as the photocatalytic degradation rate of bromomethane, apparent kinetic constant and apparent quantum efficiency was discussed.The results indicated that SO〓〓 is combined with metal ions of TiO〓 in a chelating bidentate mode.
