The measurements of coexistence curves and light scattering for {xC6H5CN + (1 −x)CH3(CH2)6CH3} 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.…”

“…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.…”

The liquid–liquid coexistence curves of {benzonitrile+n-pentadecane} and {benzonitrile+n-heptadecane} in the critical region

“…As a part of the continuous investigations on the critical behavior of the binary mixtures of (benzonitrile + n-alkanes) [10][11][12][13][14][15], in this paper, we report the measurements of the liquid + liquid coexistence curves for binary solutions of benzonitrile + n-pentadecane and benzonitrile + n-heptadecane. Detailed analysis of the asymmetry of the coexistence curves and discussion about the validity of the complete scaling theory are presented.…”
