摘要: Excess molar volumes (VEm) of binary mixtures of 2-methyl-3-buten-2-ol [CH3C(OH)
(CH3)CHCH2]with four 1-alcohols: methanol, ethanol, 1-propanol and 1-butanol at 298.15 K
and atmospheric pressure are derived from density measurements with a vibrating-tube
densimeter. All the excess volumes are negative in the systems over the entire composition
range. The results are correlated with the Redlich-Kister equation. The effects of chain
length of 1-alcohols on VmE are discussed. The apparent molar volumes of 2-methyl-3-buten-
2-ol and 1-alcohols are calculated respectively.
