CHF_3 is a potent greenhouse gas with global warming potential of 14 800 times higher than that of CO_2. Therefore,it plays a very important and critical role in the reduction of greenhouse gas emission. As CHF_3 is produced with relatively high purity,it is very beneficial to realize resource utilization rather than high-temperature incineration which is currently used by industry. This review summarizes the research on the resource utilization of waste CHF_3 gas. Via high-temperature pyrolysis (>700℃),CHF_3 can be converted to C_2F_4 (TFE,tetrafluoroethylene) and C_3F_6 (HFP, hexafluoropropylene) selectively. The presence of a suitable catalyst can significantly improve the conversion of CHF_3 and the yields of C_2F_4 and C_3F_6. Reaction of CHF_3 with CH_4 leads to the formation of CH_2=CF_2 (VDF,vinylidene fluoride),making it an alternative route for the resource utilization of CHF_3. The major shortcoming of this route is its various by-products. CF_3I can be synthesized via reaction of CHF_3 with I_2 which is another attractive process. As a fire-extinguishing agent and refrigerant,the cost of CF_3I is relatively high compared with other substitutes. In addition,CF_3I is widely used as trifluoromethyl reagent. It is reported that CHF_3 can be directly used as trifluoromethyl reagent in the presence of complicated catalysts under harsh conditions and with high cost. This route is still under preliminary exploration in the laboratory and has a long way to commercial application.
