2008 "Butadiene Purification Using Polar Solvents. Analysis of Solution Nonideality Using Data and Estimation Methods", P. M. Mathias, J. R. Elliott, Jr., and A. Klamt, Ind. Eng. Chem. Res. ASAP Article, (2008) The classical problem of 1,3-butadiene recovery from steam cracker C4 hydrocarbons is reconsidered using the COSMO-RS method.

When only one reference solvent is used, the approach reduces to the original COSMO-RS-based solubility prediction. Considerable speedup and simplification compared to the original COSMO-RS arises from the usage of approximate σ-profiles generated from a database of COSMO-files from 65000 diverse molecules.
