Critical parameters for HFC134a, HFC32 and HFC125.

Author(s) : HIGASHI Y.

Type of article: Article, IJR article

Summary

The vapour-liquid coexistence curves near the critical point have been measured by visual observation of the meniscus disappearance and three sets of 17 results have been obtained. From these measurements, the critical temperature and the critical density for these HFCs have been determined in consideration of the meniscus disappearance level as well as the intensity of the critical opalescence. The critical pressure has been calculated by the extrapolation of the vapour-pressure correlation. The accuracies are estimated.
