EXTENSION OF CPA EOS TO NFM-PENTANE & NFM-CYCLOALKANES

In our previous work, vapour-liquid phase equilibrium of N-formylmorpholine (NFM) mixtures was presented with cubic-plus-association equation of state (CPA). In this work, we used the binary liquid-liquid equilibrium data including N-Formylmorpholine (NFM), pentane and cycloalkanes and then, we proposed an association scheme that satisfied the best results for modelling. The properties considered are liquid-liquid temperature calculation in LLE. It is shown that the CPA model prdicted thermoddynamic properties very good and the best results are obtained with 4C & 2B association schemes, when 4C sceme performed better. Based on our results, we have choosen 4C association scheme as an assigned type for NFM molecule.
