A combined torsion-weighing effusion apparatus was used to measure the vapor pressures of o-, m-, and p-chloroaniline; their temperature dependences are given by the equations: O-chloroaniline, log P (kPa) = (8.63 ± 0.16) - (3006 ± 56)/T; m-chloroaniline, log P (kPa) = (8.86 ± 0.10) - (3180 ± 40)/T; p-chloroaniline, log P (kPa) = (11.20 ± 0.20) - (4170 ± 60)/T. The standard vaporization enthalpies ΔH°2 98= 57.5 ± 5, 60.9 ± 5, and 79.0 ± 5 kJ mol-1 for o-, m-, and p-chloroaniline, respectively, were derived. Free energy functions of the gaseous and solid phase for these compounds are also reported. © 1985, American Chemical Society. All rights reserved.
