Binary liquid mixtures of acetonitrile with methyl, ethyl, n-propyl and n-butyl benzoates. Variation of viscosities with temperature and composition

Abstract

Viscosity values of the binary mixtures: (I) acetomtrile + methylbenzoate: (II) acetonitrile + ethyl benzoate; (III) acetonitrile + n-propyl benzoate and (IV) acetonitrile + n-butyl benzoate at 10, 20, 30, 40 and 50 °C have been measured. Several equations for the variation of viscosity with temperature and composition of the mixtures are proposed; the effect of chain length of the esters has also been studied.
