Reasonably accurate (agreement with literature values better than 5%) heats of evaporation of some solvents (water, ether, dioxane) and NH4N03 solutions were obtained by TG methods (99). This technique also was used (100) to study the volatilization rates of some organic compounds that are of interest as environmental contaminants (naphthalene, hexachlorobenzene, 4-chlorobiphenyl, n-decane). Evaporation rates were influenced by the rates of heating (5, 10, and 25 K min-1)-A good representation of behavior was provided by the evaporation model, described in detail, provided that the surface area of the substance was known. It was assumed that equilibrium was established between condensed phase and vapor and that there was convective transport and diffusion to the container outlet. It was concluded that TG methods provide a useful method for studies of the evaporation of organic compounds.
