%X Volatilization rates of neat liquids (benzene, toluene,
fluorobenzene, bromobenzene, ethylbenzene, *m*-xylene,
*o*-xylene, *o*-dichlorobenzene, and 1-methylnaphthalene) and
of solutes (phenol, *m*-cresol, benzene, toluene, ethylbenzene,
*o*-xylene, and ethylene dibromide) from dilute water
solutions have been measured in the laboratory over a
wide range of air speeds and water-stirring rates. The overall
transfer coefficients (*K*_{L}) for individual solutes are
independent of whether they are in single- or multi-solute
solutions. The gas−film transfer coefficients (*k*_{G}) for
solutes in the two-film model, which have hitherto been
estimated by extrapolation from reference coefficients, can
now be determined directly from the volatilization rates
of neat liquids through a new algorithm. The associated liquid−film transfer coefficients (*k*_{L}) can then be obtained from
measured *K*_{L} and *k*_{G} values and solute Henry law constants
(*H*). This approach provides a novel means for checking
the precision of any *k*_{L} and *k*_{G} estimation methods for ultimate
prediction of *K*_{L}. The improved *k*_{G} estimation enables
accurate *K*_{L} predictions for low-volatility (i.e., low-*H*) solutes
where *K*_{L} and *k*_{G}*H* are essentially equal. In addition, the
prediction of *K*_{L} values for high-volatility (i.e., high-*H*) solutes,
where *K*_{L} ≅ *k*_{L}, is also improved by using appropriate
reference *k*_{L} values.
