Distribution coefficients for the liquid-liquid extraction of 2,3-butanediol (5wt%) in aqueous solutions with binary mixtures of 4-nonylphenol (0-67 vol%), toluene and several alcohols, (2-ethyl-l-hexanol, 1-oclanol and 1-decanol) at 25°C are reported. The distribution coefficients were in the following ranges: 4-nonylphenol + toluene (0-0·23), 4-nonylphenol + 2-ethyl-l-hexanol (0·23 - 0·27), 4-nonylphenol + 1-octanol (0.21-0·33) and 4-nonylphenol + 1-decanol (0·22-0·37). The largest distribution coefficient was found to be 0·37 for the mixed solvent 4-nonylphenol+1-decanol (50vol%), which shows a slight decrease in the separation factor. Activity coefficients at infinite dilution were determined using the MOSCED model and a similar trend for all the solvent mixtures of 4-nonylphenol and alcohols was found. |
