The isobaric vapor-liquid equilibrium data predictions for the binary system of cyclopentyl methyl ether andcyclopentanol were obtained using UNIFAC and modified UNIFAC Dortmund method. Group identification was done byusing artist free software with Dortmund Data Bank . The interaction parameters in the UNIFAC and modified UNIFACDortmund method, for the ether group (-CH3O) and alcohol (-OH), were used to predict VLE data. Thermodynamicconsistency of the predicted VLE data had been checked by the Herington method. The predicted data were correlatedwith Van Laar, Wilson and NRTL activity coefficient models. The binary interaction parameters of models had beenobtained by regression. The predicted VLE data of UNIFAC method were fitted much more accurately than that ofmodified UNIFAC Dortmund method by these activity coefficient models Van Laar, Wilson and NRTL.
