Regular ArticleExcess molar volumes of {xCH3(CH2)3OH + (1−x)H(CH2)ν(OCH2CH2)3OH} (ν= 1, 2, and 4) at the temperature 298.15 K

The excess molar volumesVmEof {xCH3(CH2)3OH + (1−x)H(CH2)v(OCH2CH2)3OH} for ν = 1, 2, and 4 were determined as a function of mole fractionxusing a continuous-dilution dilatometer at the temeprature 298.15 K. TheVmEvalues 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 ofVmEwith composition and the number of carbon atoms in the aliphatic chain of the alkoxyethanol is discussed, along with theVmEs for the other two homologous series reported in the literature.
