摘要：Novel surfactants and drying and/or cleaning compositions containing suchsurfactants are disclosed. The surfactants are 1:1 primary or secondary amine salts ofgamma omega -perfluoro-C6-C,8-alkyl dihydrogen phosphates and bis(y,co-perfluoro-C6-Cis-alkyl) hydrogen phosphates. The surfactants are soluble in, and convert

halocarbons, especially HFC 43-10mee (1,1,1,2,2,3,4,5,5,5-decafluoropentane), into highlyeffective displacement drying and/or cleaning compositions. These compositions havethe ability to remove water or aqueous films from the surface of a broad range ofsubstrates.
