Description
Summary:Thermodynamic data obtained for 3,3-dimethyl-2-thiabutane (methyl t-butyl sulfide) were used to determine the heights of the barriers hindering internal rotation in the molecule. The chemical thermodynamic properties in the ideal gas state (0 to 1000°K) were calculated from calorimetric, spectroscopic, and molecular structure information. Experimental studies provided the following information: values of heat capacity for the solid (15°K to the triple point), the liquid (triple point to 364°K), and the vapor (360 to 500°K); the triple point temperature; the heat of fusion; thermodynamic functions for the solid and liquid (0 to 355°K); heat of vaporization (330 to 372°K); parameters of the equation of state; vapor pressure (307 to 410°K); and the standard heat of formation at 298.15°K.
