Catalytic Dehydrofluorination of 1,1,1,2,3-Pentafluoropropane (HFC-245eb) to Environment-Friendly Refrigerant 1,1,1,2-Tetrafluoropropene (HFO-1234yf) |
| 초록 |
It is important to produce the environment-friendly refrigerant with lower global warming factors. The dehydrofluorination of 1,1,1,2,3-pentafluoropropane (HFC-245eb) to 1,1,1,2-tetrafluoropropene (HFO-1234yf) was studied using the catalysis. HFO-1234yf is an advanced refrigerant particularly for the automobiles. We confirmed that the conversion of HFO-1234yf was maintained above 60% for at least 30 hours with less deactivation. The surface-fluorinated metal oxide catalysts were prepared by modified sol-gel method and verified as highly dispersed porous catalytic materials. The structures of catalysts were observed using XPS, XRD, and TG. |
