The measurements of coexistence curves and light scattering for {xC6H5CN + (1 −x)CH3(CH2)16CH3} in the critical region

The measurements of coexistence curves and light scattering for {xC6H5CN + (1 −x)CH3(CH2)6CH3} in the critical region

“…The experiment apparatus for measurements of static light scattering have been reported previously [11]. The temperature stability of thermostat is better than ±0.003 K. The apparatus was equipped with an argon ion laser operating on 488 nm line.…”

“…In those systems, a crossover to classical mean-field should be expected. Recently the critical crossover has attracted much attention [1][2][3][4][5][6][7][8][9][10][11].…”

“…18 [11,20,21], the coexistence curves of three mixtures with one component being benzonitrile and the other being n-alkane were obtained by measurements of refractive index. This experimental results together with the data reported in this work may be used to test the validity of equations (4) to (6), and to determine the values of the exponent r, b, and n.…”

The measurements of coexistence curves and turbidity for {xC6H5CN + (1 −x)CH3(CH2)14CH3} in the critical region

“…The experimental apparatus for measurements of turbidity have been reported previously [3,4]. The sample with the critical composition was prepared in a sample cell purchased from Ace-glass Co.…”

“…The experimental values of the differences (q 2 À q 1 ) were fitted with equation (1) to obtain b and B. The results are given in table 3. The values of b and B slightly depend on the cut off values of t max , but are in very good agreement with that of other (polar liquid + n-alkane) systems we reported previously and the theoretical prediction of 0.327 [8] when the temperature approaches to the critical point.…”
