Abstract
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.Keywords
