He, N.; Jiang, T., and Zhang, L., 2018. Experimental research on the vapor pressure and critical parameters of ethyl fluoride (HFC-161). In: Liu, Z.L. and Mi, C.

Nowadays, many alternative refrigerants are studied for protecting ozonosphere. HFC161 is one of these refrigerants which are friendly to environment, because its Ozone Depleting Potentials (ODP) is zero. And it has a very low global warming potential, high cooling capacity and excellent energy efficiency. In present work, the vapor pressure of HFC161 has been measured using a static type apparatus over the temperature range from 233.15 K to 375.15 K, together with the vapor pressure of isobutane (HC-600a) measured in the temperature range from 275.60 K to 343.16 K for verifying the experimental apparatus. The measured vapor pressure data and those reported by other investigators have been evaluated, and a vapor pressure data set with reasonable accuracy has been obtained. Based on this consistent and reliable data set, a Wagner-type equation has been presented, from which the critical pressure Pc= 5.035 MPa was extrapolated. The critical temperature Tc= 375.83 K and critical density ρc= 286.215 kg•m-3 of HFC-161 have been measured in this work.
