Excess Volumes and Viscosities for the Binary Systems of 2- Propanol with alkyl acetates at 303.15 K


Measurements of excess volumes and viscosities of binary mixtures of 2-propanol with methyl acetate (MA), ethyl acetate (EA), butyl acetate (BA), and iso-amyl acetate (IAA) are reported at 303.15 K over the entire range of composition. Excess volumes are measured using batch dilometer technique. The viscosity data are analysed on the basis of corresponding states approach and Grunburg-Nissan treatment. Excess volumes are positive and deviations in viscosities are negative over the entire range of composition. The experimental results are discussed in terms of possible interactions between like and unlike molecules.
