This paper contains parameters for a universal vapor pressure equation describing methane, ethane, propane, n-butane, i-butane, R-11, R-12, R-22, R-23, R-32, R-123, R-124, R-125, R-134a, R-141b, R-142b, R-143a and R 152a. These parameters have been generated using experimental vapor pressures reported in literature. The vapor pressure equation, based upon asymptotic behavior at the triple and critical points, has three adjustable fluid-dependent parameters. This equation describes the entire vapor pressure curve within the apparent accuracy of the experimental values. © 1995.
