Abstract (en)
[origin: JPH04227803A] PURPOSE: To provide a cleaning or drying agent having a property of physical chemistry such as incombustibility or the like and hardly decomposing the stratospheric ozone by using (perfluoroalkyl)ethylene having a specific molecular construction. CONSTITUTION: (Perfluoroalkyl) ethylene represented by the formula RFCH=CH2 (RF is linear or branched perfluoroalkyl radical containing from 3 to 6 carbon atoms) is used for cleaning and degreasing of solid surfaces of metals, glass or the like and defluxing and low-temperature cleaning or the like in electronics. This material preferably has the formula C4 F9 CH=CH2 has properties of physical chemistry, such as incombustibility, high wettability, low solubility, low boiling point, same as F113, being less apt to decompose stratospheric ozone in contrast to F113.
Abstract (fr)
Pour remplacer le 1,1,2-trichloro-1,2,2-trifluoroéthane (F113) dans ses applications au nettoyage et au séchage de surfaces solides, l'invention propose d'utiliser un (perfluoroalkyl)-éthylène de formule : RFCH=CH2 dans laquelle RF représente un radical perfluoroalkyle, linéaire ou ramifié, contenant de 3 à 6 atomes de carbone. Contrairement au F113, les (perfluoroalkyl)-éthylènes ne sont pas susceptibles de dégrader l'ozone stratosphérique.
