Abstract
The chemical thermodynamic properties of 2-butanethiol in the ideal gaseous state (0 to 1000/sup 0/K) were calculated by use of calorimetric, spectroscopic and molecular structure information. The thermodynamic and spectroscopic results show that 2-butanethiol exists as a mixture of molecules in three distinct rotational conformations--two with about equal energies and a third with about 1.0 kcal. mole/sup -1/ higher energy. 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 307/sup 0/K) and the vapor (346 to 453/sup 0/K); the triple point temperature; the heat of fusion; thermodynamic functions for the solid and liquid (0 to 310/sup 0/K); heat of vaporization (318 to 358/sup 0/K); parameters of the equation of state; vapor pressure (38 to 121/sup 0/); and standard heat of formation at 298.16/sup 0/K.
