✦ Synopsis

The excess molar volumes V E m of {xCH3(CH2)3OH + (1x)H( CH2)n(OCH2CH2)3OH} for n = 1, 2, and 4 were determined as a function of mole fraction x using a continuous-dilution dilatometer at the temperature 298.15 K. The V E m values decreased as the alkyl chain length of the alkoxyethanol increased. Excess molar volumes were negative over the whole mole fraction range for the systems n = 2 and n = 4, and positive for n = 1. The behaviour of V E m with composition and the number of carbon atoms in the aliphatic chain of the alkoxyethanol is discussed, along with the V E m s for the other two homologous series reported in the literature.
