Abstract (en)

Use of hydrofluoroalkanes of formula Rf(CH2CF2)nCH=CF2 (I), where n = 1 or 2 and Rf = 1-3C perfluoroalkyl, as agents for cleaning solid surfaces, is new. Also claimed are compsns. for cleaning solid surfaces, comprising a cpd. (I) and a normally liq. organic solvent. (I) are described in US3106589 and 3116337.

Abstract (fr)

Pour remplacer le 1,1,2-trichloro-1,2,2-trifluoroéthane (F 113) ou le 1,1-dichloro-1-fluoroéthane (F141b) dans leurs applications au nettoyage de surfaces solides, l'invention propose d'utiliser un hydrofluoroalcène de formule générale: RF-(CH2-CF2)n-CH = CF2 dans laquelle n est égal à 1 ou 2 et RF représente un radical perfluoroalkyle. Les hydrofluoroalcènes ne sont pas susceptibles de dégrader l'ozone stratosphérique.
