Excess molar volumes of { xCH 3(CH 2) 3OH + (1− x)H(CH 2) ν(OCH 2CH 2) 3OH} ( ν= 1, 2, and 4) at the temperature 298.15 K

Abstract

The excess molar volumes V m Eof { xCH 3(CH 2) 3OH + (1− x)H(CH 2) v (OCH 2CH 2) 3OH} for ν = 1, 2, and 4 were determined as a function of mole fraction xusing a continuous-dilution dilatometer at the temeprature 298.15 K. The V m Evalues decreased as the alkyl chain length of the alkoxyethanol increased. Excess molar volumes were negative over the whole mole fraction range for the systems ν = 2 and ν = 4, and positive for ν = 1. The behaviour of V m Ewith composition and the number of carbon atoms in the aliphatic chain of the alkoxyethanol is discussed, along with the V m Es for the other two homologous series reported in the literature.
