Surface Tension of Mixtures of Tetrahydrofuran or Tetrahydropyran with Isomeric Chlorobutanes

Experimental surface tensions for mixtures containing tetrahydrofuran or tetrahydropyran and 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane, or 2-chloro-2-methylpropane, measured with a drop volume tensiometer, are reported at temperatures of 298.15 and 313.15 K. Taking into account the Li-model for the surface tension, the variation of the iInteraction energy parameters with surface area is estimated.
