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

Critical behaviour of binary mixture of {xC6H5CN+(1−x)CH3(CH2)7CH3}: Measurements of coexistence curves, light scattering, and heat capacity

“…(1) with a weighted nonlinear least-squares routine. The values of M, B / , and (1 À / c ) obtained from this work and the previous works [3][4][5][6] are listed in rows 2, 3 and 4 of table 7, respectively. As it can be seen, the critical volume fraction of n-alkane decreases, and the amplitude B / increases with increase of the n-alkyl chain length.…”

“…(1) to obtain b and B. The results are given in table 4. Here and hereafter, without special explanations, the listed errors of parameters represent the 1 standard deviation from the fits.…”

“…As a part of the continuous investigations on the critical behaviour of the binary mixtures of (benzonitrile + n-alkanes) [3][4][5][6], in this paper, we report the measurements of the liquid + liquid coexistence, light scattering, and isobaric heat capacity per unit volume for the binary solutions of (benzonitrile + n-nonane). The results are analyzed to obtain the critical exponents and the critical 0021-9614/$ -see front matter Ó 2010 Elsevier Ltd. All rights reserved.…”

Critical behavior of binary mixture of {x C6H5CN + (1 −x) CH3(CH2)12CH3}: Measurements of coexistence curves, turbidity, and heat capacity

“…The apparatus for turbidity measurement has been described previously [18,19]. The sample with the critical composition was prepared in the optical cell purchased from Ace-glass Co. with inner diameter of 0.680 cm.…”

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

“…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.…”
