Study of the Surface Tension of Chlorocyclohexane or Bromocyclohexane with Some Cyclic Ethers

Experimental surface tensions for mixtures formed by chlorocyclohexane or bromocyclohexane and a cyclic ether (tetrahydropyran, tetrahydrofuran, 2-methyltetrahydrofuran, or 2,5-dimethyltetrahydrofuran) have been measured with a drop volume tensiometer at temperatures of 298.15 K and 313.15 K. The surface tension deviations for the binary mixtures, that is, for each mixture, the deviation of the surface tension from a mole fraction average, have been calculated from the experimental data.
