Description
Summary:The simultaneous correlation of VLE and excess properties (HE, cPE) for diether + n-alkane systems was performed in our previous paper by the cubic equation of state which incorporates the activity coefficient model (CEOS/GE).With the same aim, in the present work, a completely different approach based on a polynomial equation (Kohler model) was considered. This method gave results on the same systems which could be estimated as being comparable to GEOS/GE models for the simultaneous correlation of two and with considerably improved fits, of three properties. Simultano korelisanje VLE i dopunskih velicina (HE, cP E) izvrseno je u prethodnom radu na sistemima dietri + n-alkani koriscenjem kubne jednacine stanja koja ukljucuje model za koeficijente aktivnosti (CEOS/GE). Sa istim ciljem, u ovom radu primenjen je potpuno drugaciji pristup baziran na koriscenju polinoma (Kohlerov model). Ovaj pristup dao je rezultate na istim sistemima koji su u slucaju simultanog korelisanja dve osobine slicnog kvaliteta kao i pri koriscenju CEOS/GE modela dok su rezultati pri simultanom korelisanju tri osobine znacajno poboljsani.
