ABSTRACT
The specific volumes of chlorodifluoromethane have been measured up to 500 MPa at eight isotherms ranging from (298.2 to 573.2) K. Experiments were performed with a thin-walled sample holder with equal pressure inside and outside. The volume change of the sample was determined with a separation system at 298.2 K by making use of a magnetic float on mercury and a linear variable differential transformer. The specific volume of chlorodifluoromethane varies in this region from (0.579 to 4.957) cm3*g-1. The experimental uncertainty in specific volumes was estimated to be no greater than +/- 0.4 %. The Tait equation was used to correlate the data.
