FLUOROCARBONS AS VOLATILE SURFACTANTS

Surface active properties of volatile vapors of fluorocarbon substance s such as C6F14, C8F18, and C10F18 have been discovered. In a new phen omenon of capillary instability some perpetual oscillatory and rotary movements of many liquids take place due to a change of their surface tensions by 10-30% at contact with C8F18 vapor at room temperature. Fe atures and possible applications of volatile surfactants are discussed .
