Abstract

The molar volumes or densities of six pure alcohols belonged to biofuel industry have been estimated for different values of temperatures within the range between 280 K and 333 K, using a model developed from vapour-liquid equilibrium equation or Clausius-Clapeyron Equation. The second virial coefficient (B) has been calculated from predictive data applied to the model. As widely known, variations in the B value would reflect in the compounds molar volumes with similar result. In this work, it was observed that the deviations were positive for all studied species, and they increased among long carbon chain alcohols. When avalaible, a comparison between experimental and predicted molar volume was done.
