Abstract: A self-made vapor-liquid equilibrium device was used to measure the vapor-liquid equilibrium data of furfural-cyclohexanol, furfural-camphene and furfural-cyclohexanol-camphene at 101.3kPa. The Wilson equation parameters were obtained by the correlation and calculation of the measured data.The calculated data of temperature and the mass fractions of gaseous components of furfural-cyclohexanol and furfural-comphene at 101.3kPa were obtained by Wilson equation and agreed with the industrial data well. The thermodynamic consistency of the two groups binary vapor-liquid equilibrium data were checked with the area integral method. The results met the with requirements. The data of furfural-cyclohexanol-camphene ternary vapor-liquid equilibrium were measured and fitted. The results showed that at 421.5K, the molar fraction of furfural was the maximum and the molar fraction of cyclohexanol was the minimum in the vapor phase, so that furfural and cyclohexanol could be separated at this temperature. And it could be regarded as basic theory for the separation of furfural and cyclohexanol in engineering.
