چکیده
Isobaric vapor–liquid equilibrium (VLE) data for 2-propanol + 1-butanol, 2-propanol + 1-pentanol, 1butanol + 1-pentanol and 2-propanol + 1-butanol + 1-pentanol were measured at 101.3 kPa by using an improved Rose still. All the binary VLE data have passed the traditional area test proposed by Herington. The interaction parameters for the Wilson, NRTL and UNIQUAC equations were determined by regressvailable online 7 January 2013 eywords: -Propanol -Butanol -Pentanol ing the binary VLE data. The prediction for ternary system was given by using the three pairs of binary parameters correlated. And the ternary data predicted agreed well with the experiment data. © 2013 Elsevier B.V.

Measurement and Modeling of High Pressure Vapor-liquid Equilibria of Co2 + Alcohol Binary Systems
A new apparatus based on a static-analytic method was developed in this work to perform high-pressure vapor-liquid equilibria measurements up to 68 MPa and 373 K. In order to validate this new apparatus, vapor-liquid equilibria of the binary system CO2 + ethanol was measured at temperatures of 313, 323 and 338 K and pressures from 1.2 to 11 MPa. Results were compared with data from the literatu...

The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results w...

BACKGROUND The primary components of lignocellulosic biomass such as sorghum bagasse are cellulose, hemicellulose, and lignin. Each component can be utilized as a sustainable resource for producing biofuels and bio-based products. However, due to their complicated structures, fractionation of lignocellulosic biomass components is required. Organosolv pretreatment is an attractive method for thi...
