Use of (perfluoroalkyl)ethylenes as cleaning or drying agents, and compositions which can be used for this purpose |
摘要 |
To replace 1,1,2-trichloro-1,2,2-trifluoroethane (F113) in its applications to the cleaning and drying of solid surfaces, the invention propose to employ a (perfluoroalkyl) ethylene of formula: RfCH=CH2 in which Rf denotes a linear or branched perfluoroalkyl radical containing from 3 to 6 carbon atoms. In contrast to F113, (perfluoroalkyl)ethylenes are not liable to degrade stratospheric ozone.
