| Abstract | The influence of a thin spreading solvent film (ethanol, diethyl ether, and three fractions of petroleum ether boiling at 30-60 A degrees C, 60-90 A degrees C, and 90-120 A degrees C) on the properties of hexadecan-1-ol (C(16)H(33)OH) monolayers at the air-water interface was studied. The specific evaporation resistance and the surface pressure were determined to describe the spreading behavior of the C(16)H(33)OH monolayers. The physical properties of the solvents and the images obtained in an atomic force microscope were examined. The time of establishing the equilibrium spreading surface pressure of monolayers can be reduced using a more volatile solvent with a lower boiling point and a lower relative density. The influence of the monolayer nature on water evaporation corresponds to the order of changing the solvent spreading rate: petroleum ether (30-60 A degrees C) > diethyl ether > ethanol > petroleum ether (60-90 A degrees C) > petroleum ether (90-120 A degrees C). The monolayers formed upon petroleum ether (30-60 A degrees C) spreading form a film with a less deficient and relatively planar surface. When ethanol is used as a spreading solvent, water evaporation is accelerated rather than retarded, while petroleum ether (30-60 A degrees C) is more appropriate for this purpose. |
