Predictions of azeotropes formed from fluorinated ethers, ethanes, and propanes.

Author(s) : GAGE C. L., KAZACHKI G. S.

Summary

Azeotrope formation was predicted using an interaction parameter based on the dipole moments and volumes of the components. Dipole moments for the new compounds were predicted from the molecular structure. Of 20 fluorinated ether and hydrocarbon pairs tested, seven were found to form azeotropes. Results from this work predicted azeotropes with boiling points between -46 and -19 deg C, indicating potential replacements for R12 and R502. Azeotrope performance in vapour-compression cycles was then evaluated.
