The pure substances were: toluene,

Various representative models are discussed.

Systematic dielectric measurements performed for all I(W/O), the transparent isotropic W/O type solubility area, show anomalies in both the low-frequency conductivity and permittivity.

A falling body viscometer was used for measuring the dynamic viscosity above 0.1 MPa, while at 0.1 MPa the viscosity was obtained with an Ubbelohde

The density measurements were performed up to 60 MPa with an uncertainty of 1_10 &4 g } cm &3. The viscosity at atmospheric pressure was measured with an Ubbelohde-type glass capillary tube viscometer with an uncertainty of \10. At pressures up to 100 MPa the viscosity was determined with a falling ball viscometer with an uncertainty of \20. The density (410 experimental values) and viscosity data (184 experimental values) were fitted to several correlation equations.

A phenomenological equation has been derived from the experimental viscosity values. These have also been compared with the values obtained numerically from some models. The authors have more specially studied the corresponding-states model. A semiempirical relation is given for n-alkanes, taking n-C¹⁴ as a reference. This relation also accounts for the results obtained for alkane mixtures and alkylbenzenes. The limits of the method are also indicated. 19 references, 9 figures, 10 tables.

Two systems were studied: water/AOT/dodecane and water/AOT/isooctane (AOT = sodium ethylhexylsulfoccinate). The analysis of the experimental heats of crystallization allows one to differentiate samples possessing free water from samples without free water. We find a critical value of the molar ratio nc = [water]/[AOT] N 6.5 for the water/AOT/dodecane system and n, 4.5 for the water/AOT/isooctane system (for n < n, all the water is bounded).
