Volatilisation of chemicals—Relative loss rates and the estimation of vapour pressures

Vapor pressures and Henry's law constants of polychlorinated biphenyls

“…chlorobiphenyl are 2.5 Pa and 3.5 X 10"6 Pa, respectively. These translate into solid vapor pressures of 0.94 Pa and 6.9 X 10"9 Pa, which may be compared with some literature values of 1.15 and 1.01 Pa (12,15) and 2.8 X 10"8 and 2.8 X 10"9 Pa (derived from subcooled liquid values) (11,16). The apparent lower precision with decachlorobiphenyl may reflect in part the larger experimental error associated with measurement of such small vapor pressures.…”

When this ratio is less than 1, its negative reciprocal is reported.…”
