'''二氟一氯甲烷'''，别名'''[[氟利昂]]-22'''、'''R-22'''，分子式CHClF<sub>2</sub>。

==性质==
无色近乎无臭气体。不可燃。微溶于水。

==制备==
由[[三氯甲烷]]和[[氟化氢]]在[[五氯化锑]]催化下反应而得。
:<math>\ CHCl_3+2HF \ \xrightarrow [30\!-\!80^oC, \ 392.25\!-\!588.39kPa]{SbCl_5} \ CHClF_2+2HCl</math>

==用途==
用作[[冷媒|致冷剂]]、[[聚四氟乙烯]]树脂原料和[[灭火剂]]等。但由於會破壞[[臭氧層]]，近年來已逐漸由其他化學物質所取代。
