塩素化C,～2有機溶媒の蒸発速度

抄録

Evaporation rates of pure and binary systems of chlorinated C_1-2 hydrocarbons were measured at 298 K and compared with those estimated from the Knudsen type equation. As the binary solvent mixtures, 10 kinds of chlorinated C_1-2 hydrocarbons were combined with 4 kinds of alcohols of C_1-4, 5 kinds of alkanes of C_6-10, and 3 kinds of aromatics (benzene, toluene, and o-xylene). The evaporation rates of the mixtures observed agreed with those estimated from the known evaporation rates of the pure solvents and from the mean evaporation coefficients depending on the gas-phase turbulence using the activity coefficients calculated from the UNIFAC method.
