Abstract
P-V-T data for propyne have been fit using the Martin-Hou and the Benedict-Webb-Rubin equations of state. The Martin-Hou equation, with its constants calculated from the critical properties and a vapor pressure point for the gas, fit up to 1.1 to 1.5 times the critical density with deviations of less than 1%. The Benedict-Webb-Rubin equation, with its constants calculated by the method of Joffe, resulted in greater deviations in the low pressure region than did the Martin-Hou equation; however, it also provided a better approximation of the data at high pressures and lower temperatures. The best over-all fit was obtained using the B-W-R equation, with its coefficients determined by a multiple non-linear regression technique, to give a "least squares" fit to the data themselves. An IBM 7090 computer was used for this calculation.
