摘要：
α-Pinene has a special bicyclo and C=C structure. In order to predict the vapor-liquid equilibrium (VLE) data for the system containing α-pinene more accurately, α-pinene was divided into one bicyclo[3.1.1]hept-2-ene and three CH3 according to the theory of UNIFAC model. With the correlation of VLE data for the binary system containing α-pinene, group interaction parameters for bicyclo[3.1.1]hept-2-ene with CH3, C=C, ACH and ACCH3 were obtained, which expands the application of the UNIFAC model. Comparing with the original UNIFAC model using only CH3, C=C, ACH and ACCH3 to predict VLE data of ternary system containing α-pinene, the average deviation of vapor composition and temperature from the prediction of VLE data by new group parameters are smaller than that by the original group parameters, indicating that the new group for α-pinene is more reasonable. © All Rights Reserved
