Densities of binary mixtures containing N,N'-salicylidenephenyl diamine (Salophen)+ organic solvents {dimethylsulfoxide (DMSO), N,N'-dimethylacetamide (DMA), 1,4-dioxacyclohexane (1,4-dioxane), and oxolane (THF)} have been measured at 10K intervals from 288.15K to 318.15K. Using these data, apparent molar volumes (V-phi), standard partial molar volumes (V-phi(0)), standard partial molar isobaric expansivity (E-phi(0)) Hepler's constant (partial derivative V-2(phi)0/partial derivative T-2)(p), and isobaric thermal expansion coefficient (alpha) have been calculated 0 75 for all the mixtures. The values of interaction volumes (V-int), and cavity volumes (V-cay) have also been estimated using the scaled particle theory [20]. The results show that Salophen in the studied organic solvents predominantly acts as a structure-breaker. (C) 2013 Elsevier B.V. All rights reserved.
