Abstract
Measurements of the temperature dependence of specific heat of a perfluoromethylcyclohexane/ carbon tetrachloride mixture of critical composition near the critical solution temperature Tc are reported. The experiments are carried out in an isothermal heat flow calorimeter in a temperature range of 4×10−3 K? (T-Tc) ?10.921 K. The experimental results are discussed in terms of current concepts of critical phenomena.
