| titleOfInvention | Azeotropic composition and application thereof |
| abstract | The invention belongs to the field of hydrofluoroethers, and particularly relates to an azeotropic composition and application thereof. Comprises the following components: (1) hydrofluoroether compound, F [ CF (CF) ] 3 )CF 2 O] x ‑R H (ii) a Wherein x is 2-7; r H ＝CH 3 、C 2 H 5 、n‑C 3 H 7 Or i-C 3 H 7 One of (1); (2) an organic solvent. The present invention provides the use of an azeotropic composition as a cleaning solvent by contacting the object to be cleaned with the azeotropic composition of the present invention or its vapor until the unwanted contaminants are dissolved, dispersed or displaced and rinsed away. The azeotropic compositions are cleaning solvents having a boiling range suitable for a variety of cleaning applications, acceptable stability, low toxicity, short atmospheric lifetime, low global warming potential, and low ozone depletion potential. |
