By means of the capillary rise method, we have measured the surface tension of four different kinds of halogenated hydrocarbons, namely, trichlorofluoromethane (CCl3F; R 11), dichlorodifluoromethane (CCl2F2; R 12), trichlorotrifluoroethane (C2Cl3F3; R 113), and dichlorotetrafluorethane (C2Cl2F4; R 114). Under the coexistence of the sample liquid with its saturated vapor in equilibrium, the measurements have been performed within the maximum uncertainty of 0.12 mN · m-1 at temperatures from 273 K up to near the critical point of the respective substances. Under the same experimental conditions, two sets of surface tension data have been obtained with two different Pyrex glass capillaries whose inner radii were 0.1536±0.0004 and 0.1724±0.0005 mm, respectively. The two sets of data were in agreement within 0.1 mN · m-1. The data were represented by van der Waals-type correlations with a standard deviation of 0.10 mN · m-1 for CCl3F, 0.04 mN · m-1 for CCl2F2, 0.08 mN · m-1 for C2Cl3F3, and 0.07 mN · m-1 for C2Cl2F4, respectively. © 1981 Plenum Publishing Corporation.
