Measurement of the Vapor-Pressure of Several Low-Volatility Organochlorine Chemicals at Low-Temperatures with a Gas Saturation Method
The vapor pressures of hexachlorobenzene, gamma-hexachlorocyclohexane, p,p’-DDT, i.e., 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethane, 4-monochlorobiphenyl, 4,4’-dichlorobiphenyl, 2,3,4,5-tetrachlorobiphenyl and 2,2’,4,4’,6,6’-hexachlorobiphenyl were measured in the temperature range -30 to +40-degrees-C with a gas saturation technique. Coefficients describing the temperature dependence of these vapor pressures are reported. Enthalpies of sublimation derived from these data show no significant temperature dependence in the temperature range investigated.
