Abstract
The coexistence curves of (T, n), (T, ϕ) and (T, ψ) (n, ϕ, ψ are the refractive index, the volume fraction, and the effective volume fraction, respectively) for two ternary nonaqueous microemulsion systems have been determined at constant pressure and a constant molar ratio ω of DMA to AOT. The critical exponent β and the critical amplitude B have been deduced, and the values of β were consistent with the theory of 3D-Ising in a region sufficiently close to the critical temperature. The results show that the coexistence curves have been successfully described by the Wegner equation and the expression for the diameter.
