摘要：

A solution for the isothermal evaporation of a pure volatile liquid that accounts for the moving liquid-vapor interface is presented. This solution is compared with new experimental data for the evaporation of methanol and methyl formate into air at 25.4 degrees C. The resulting diffusion coefficients for these systems are in excellent agreement with reported values (corrected for temperature and pressure). (C) 1997 Elsevier Science Ltd.
