DETERMINATION OF ACTIVITY COEFFICIENT AT INFINITE DILUTION OF HYDROCARBONS IN FURFURAL AT 298.15 K THROUGH SPME-GC/FID. In this work a new method (SPME-GC/FID) was developed to analyze the activity of binary liquid mixtures. The purpose is to demonstrate that SPME is capable lobe used to determinate activity coefficients at infinite dilution knowing the fiber properties, with a lower cost than the conventional methods encountered in literature such as GLC. The activity coefficients at infinite dilution in furfural for n-hexane, n-heptane and cyclohexane at 298.15 K was determined using SPME and deviations of literature data was about 7%.
