The vapor pressures of several aliphatic and phenyl substituted primary amines at T/K = 298.15 are measured by transpiration studies, and their vaporization enthalpies are calculated. The results were combined with compatible literature values to evaluate both the vaporization enthalpy and vapor pressure of (d)-amphetamine by correlation gas chromatography. The results are compared to existing values either estimated or measured for racemic amphetamine. Vaporization enthalpies and vapor pressures at T/K = 298.15 of the following were measured by transpiration (kJ.mol(-1), p/Pa): 1-heptanamine, (49.75 +/- 0.38, 291); 1-octanamine, (55.05 +/- 0.29, 108); 1-decanamine, (64.94 +/- 0.32, 12); benzylamine, (54.32 +/- 0.32, 88); (dl)-alpha-methylbenzylamine, (55.26 +/- 0.33, 82); 2-phenethylamine (57.51 +/- 0.35, 43). The use of several of these materials as standards resulted in a vaporization enthalpy and vapor pressure for (d)-amphetamine at T/K = 298.15 of (58.2 +/- 2.7) kJ mol(-1) and (38 +/- 12) Pa.
