摘　　要：氢氟烯烃(HFO)因其具有零消耗臭氧层物质、极低的温室效应潜能值的特点,被认为是理想的高压工作流体,所以在制冷和医用气雾剂等领域很有应用价值。HFC-134a在制冷、灭火、气溶胶、发泡和清洗等领域有着广泛应用,是较为理想的制冷剂替代品,但HFC-134a温室效应潜值较高(GWP=1300),在大气中停留的时间较长,是《京都议定书》和《蒙特利尔议定书》的受控温室气体之一。HFO-1234yf作为HFC-134a的替代物,其温室效应潜值很低(GWP<4),有着广泛的应用前景。从HFO-1234yf的特性、制备方法及应用前景做了简单综述,以期能对ODS替代物的研究提供参考。The hydrofluoroolefin(HFO)is considered to be an ideal high-pressure working fluid due to its zero ozone depleting substances and extremely low greenhouse effect potential,so it has great application value in the fields of refrigeration and medical aerosols.The HFC-134 a is widely used in the fields of refrigeration,fire extinguishing,aerosol,foaming and cleaning.It is an ideal refrigerant substitute,but the HFC-134 a has a high greenhouse effect potential(GWP=1300)and can stay in the atmosphere for a long time,so the HFC-134 a is one of the controlled greenhouse gases under the"Kyoto Protocol"and the"Montreal Protocol".As a substitute for the HFC-134 a,the HFO-1234 yf has a very low greenhouse effect potential(GWP<4)and a wide range of application prospects.The characteristics,preparation methods and application prospects of HFO-1234 yf are briefly reviewed in order to provide a reference for the research on the ODS substitutes.
