The commonly used oxygenating additives are methyl 1,1-dimethylethyl ether MTBE and light alkanols like methanol and ethanol. Una vez calculados se pueden correlacionar con modelos o ecuaciones. This trend of activity coefficients is in agreement with the data reported by Oracz [1] and by Park et al. Forziati, A. Very good separation of peaks was achieved under these conditions, and calibration analyses were carried out to convert the peak area ratios to the mass composition of the sample.
