Viscosities of a ternary mixture containing CH COOCH , CH OH, and CH CH CH OH at T s 298.15 K and atmospheric pressure have been measured over the whole range of mixture compositions. Viscosity deviations and excess molar Gibbs energy of activation of flow for the ternary system were calculated and
The coexistence curves for x CHCOOC H q 1 y x CH CH CH have been 2 5 2 3 2 5 3 determined within about 10 K from the critical temperature by measurements of the refractive Ε½ . index. The critical amplitude B, and the critical exponent β€ have been deduced from T, n , Ε½ . Ε½ . T, x and T, curves where
