Abstract

Due to the increased interest for using tertiary ethers as fuel additives (such as TAME – tert-amyl-methyl-ether synthesis), the research intensified to study its thermodynamic aspects. Mathematical modelling of tertiary ethers synthesis includes a number of elements characterizing the process thermodynamics. The liquid – vapour equilibrium data is used to get an insight about the deviations from ideal behaviour of the components in the two phases. This kind of information needed to characterize the process thermodynamics are widely available from literature, but sometimes with doubts related to accuracy, which leads to the necessity of experimental checking. TAME is formed by reaction of isoamylenes present in FCC C 5-fraction (2-methyl-1-butene and 2-methyl-2-butene) with methanol (MeOH).
The isobaric vapor liquid equilibrium data (T-x-y) for the binary mixtures of 2-methyl-2-butene and TAME, 2-methyl-1-butene and TAME are experimentally determined at 101.3 kPa. The study performed gives a thorough determination of the whole binary system equilibrium data by means of a dynamic ebullometer Fisher 602 VLE. The analysis of both liquid and vapour phases were performed using a HP 5890 Series II Plus Gas Chromatograph with FID detector.
