2-methyl-2-butanethiol: chemical thermodynamic properties and rotational isomerism
Thermodynamic and spectroscopic properties of 2-methyl-2-butanethiol (t-amyl mercaptan) were measured, and the results were used for calculating the chemical thermodynamic properties in the ideal gas state (0 to 1000/sup 0/K) and for studying the rotational isomerism of the compound. Experimental thermodynamic 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 347/sup 0/K), and the vapor (300 to 500/sup 0/K); the triple point and transition temperatures; the heats of fusion and transition; thermodynamic functions for the solid and liquid (0 to 350/sup 0/K); heat of vaporization (330 to 372/sup 0/K); parameters of the equation of state; vapor pressure (324 to 411/sup 0/K); and the standard heat of formation at 298.15/sup 0/K. The infrared spectrum of the crystals and relative intensity vs. temperature data for a pair of infrared bands of the liquid were determined.
