【 摘 要 】

Densities of the binary mixtures consist of methanol, ethanol, 1- propanol,1-butanol and 1-pentanol with 1,3 Propanediol were measured at temperatures(293.15, 298.15, 303.15 and 313.15) K and atmospheric pressure. Measurementshave been made over the full range of compositions and for the pure compoundsby using a vibrating tube densimeter. Excess molar volumes have been obtainedfrom these experimental results and were fitted to a Redlich-Kister typeexpansion. The results were interpreted in terms of molecular interactionsand structural factors of the alcohols. It was observed that an increase ofthe alcohol carbon chain length led to lower interactions on mixing. ThePeng-Robinson-Stryjek-Vera (PRSV) equation of state has been used tocorrelate the binary excess molar volumes.
