摘要
The catalyst of lanthanum phosphotungstate with Dawson structure supported on activated carbon (La2P2W18O62/C) was prepared by impregnation method and characterized by FT-IR, XRD, SEM and TG. The catalytic performance was studied in the catalytic synthesis of tetrahydrofuran from 1, 4-butanediol.The effects of catalyst dosage, reaction time, reaction temperature and repeated times of catalyst on the yield of tetrahydrofuran were investigated. The results showed that under the optimal conditions, i.e., w(Catalyst) = 3.9%(Relative to the dosage of 1, 4-butanediol), reaction temperature of 185°C and reaction time of 40 min, the yield of tetrahydrofuran reached 94.9%. The activity of La2P2W18O62/C catalyst remained basically unchanged after five runs and the yield of tetrahydrofuran was still above 91.3%.
