Volumetric properties of (alkoxypropanol + n-alkanol) systems at 298.15 K

Abstract

Excess molar volumes V m E for binary liquid mixtures of ( n-alkanol + 1-methoxy-2-propanol, 1-ethoxy-2-propanol, 1-propoxy-2-propanol, 1-butoxy-2-propanol, or 1- tert-butoxy-2-propanol) have been measured as a function of composition using a continuous dilution dilatometer at 298.15 K and atmospheric pressure over the full range of composition. The n-alkanols were methanol, ethanol, and 1-propanol. The V m E for each of the mixture studied are negative over the whole mole fraction range. For each case, the V m E increases in a positive direction with increase in chain length of the n-alkanol. The V m E results have been used to estimate the excess partial molar volumes V¯ m,i E of the components.
