Abstract: 
Evaporation from the surface of hydrocarbon liquids without cover, at applying native glass microspheres cover, and coated with ultralight surfactant system including microspheres has been investigated. A series of ultralight surface-active systems that interact with the surface of the microspheres and prevent evaporation of hydro-carbon liquids by 98‒99.6 % has been developed. For the first time it was found that native gas-filled glass microspheres of low density (200‒410 kg/m3) while providing excellent buoyancy do not protect but increase the evaporation of individual saturated hydrocarbons of homologous series C5‒C10.
