Molecular Structure-Based Methods of Property Prediction in Application to Lipids: A Review and Refinement
The paper is a review of the combined group contribution (GC)–atom connectivity index (CI) approachfor prediction of physical and thermodynamic properties of organic chemicals and their mixtures withspecial emphasis on lipids. The combined approach employs carefully selected datasets of different purecomponent properties to develop simultaneously two parallel models, one based on group contribu-tion and another based on atom connectivity, for each property.
The lipids present in the databaseare regarded as a separate class, for which special models for pure component properties, primary andtemperature dependent, have been developed. For mixtures, properties related to phase equilibria aremodeled with GE-based models (UNIQUAC, UNIFAC, NRTL, and combined UNIFAC-CI method).
The col-lected phase equilibrium data for VLE and SLE have been tested for thermodynamic consistency togetherwith a performance evaluation of the GE-models. The paper also reviews the role of the databases andthe mathematical and thermodynamic consistency of the measured/estimated data and the predictivenature of the developed models.
