Physical properties of fluorinated propane and butane derivatives as alternative refrigerants.

Author(s) : BEYERLEIN A. L., DESMARTEAU D. D., HWANG S. H., SMITH N. D., JOYNER P. A.

Summary

Physical property measurements are presented for 24 fluorinated propane and butane derivatives and one fluorinated ether. Measured vapour pressures are obtained up to the critical temperature for four of the compounds: R227ea, R245cb, R236ea (all HFCs), and R125a (an HFE). These measured data may be used to evaluate the chemicals as alternative refrigerants. Modified corresponding states methods, using R134a (an HFC) as a reference fluid, are presented as a means of obtaining the needed estimated data, and the accuracy of these methods is judged by comparisons with measured data.
