Note générale :	Volatilization is a significant process in determining the fate of many organic compounds in treams and rivers. Quantifying this process requires knowledge of the mass-transfer coefficient from water, which is a function of the gas-film and liquid-film coefficients. The gas-film coefficient can be determined by seasuring the flux for the volatilization of pure organic liquids. Ten the report shows that the gas-film coefficient for acetone was much more dependent on temperature than more the coefficient for the other ketones.
