Excess molar volumes of binary mixtures of alkyl acetates with hexane, tetrachloromethane, and trichloromethane

Excess molar volumes VE have been determined from density ρ measurements, using a vibrating-tube digital densimeter DMA 60/602 for binary mixtures of methyl acetate (MA), ethyl acetate (EA), and n-amyl acetate (n-AA) with n-hexane (C6H12), tetrachloromethane (CCl4), trichloromethane (CHCl3) and of iso-amyl acetate (i-AA) with CCl4, and CHCl3. The results we refitted to the polynomial relations to obtain the coefficients and the standard deviations. The results have been analyzed in terms of disruption of dipolar association of alkyl acetates and molecular interactions between alkyl acetate and chloromethane.
