摘要：

Infinite-dilution activity coefficients were measured at both concentration limits and at two different temperatures for each of the systems ethyl formate/acetonitrile, ethyl formate/benzene, ethyl formate/methyl ethyl ketone, ethyl formate/chloroform and ethyl formate/tetrachloromethane, using the technique of comparative ebulliometry. The data obtained were used to estimate UNIFAC interaction parameters for the groups HCOO/CCN, HCOO/ACH, HCOO/CH2CO, HCOO/CCl3 and HCOO/CCl4, which are not available in the infinite-dilution specific parameter table or are not reliable. These parameters were used to predict vapor-liquid equilibrium data for systems containing the same groups and a comparison between experimental and predicted values is presented.
