Abstract
The chemical thermodynamic properties of 2-methyl-1-propanethiol in the vapor state (0 to 1000/sup 0/K) were calculated by methods of statistical mechanics utilizing observed values of the standard entropy, heat capacity and heat of formation. The thermodynamic results are consistent with spectroscopic evidence for a small energy difference between rotational isomers. Experimental studies provided the following information: Values of heat capacity for the solid (12/sup 0/K to the triple point), the liquid (triple point to 350/sup 0/K) and the vapor (350 to 500/sup 0/K); the triple point temperature; the heat of fusion; thermodynamic functions for the solid and liquid (0 to 350/sup 0/K); heat of vaporization (321 to 362/sup 0/K); second virial coefficient, B, in the equation of state, PV = RT(1 + B/V); vapor pressure; and standard heat of formation.
