Isobaric binary vapor-liquid equilibriums. Systems acetonitrile-ethylbenzene and acetonitrile-p-xylene

Abstract

The infinite-line-charge theory (20) gives the dependence of 0V on In c at extreme (but not infinite) dilution (d0v/d In c) = (azp Vm/2zcX)(d In c/d In P) =

Isobaric vapor-liquid equilibria for the binary systems formed by acetonitrile and aromatic hydrocarbons

“…As observed previously (13,17), the modified Peng-Robinson model was successful in predicting the qualitative characteristics of the experimentally observed behavior for all the cases studied. The quantitative agreement between experimental results and model predictions derived from binary data is good in most cases, with the agreement being closest at low acid mole fractions, closest to the binary data from which the correlation parameters were derived.…”
