Abstract
The chemical equilibrium for the liquid-phase decomposition of 2-methy l-2-methoxybutane (tert-amyl methyl ether) was studied experimentally in the temperature range 313-353 K and at 700 kPa. To reach decomposit ion equilibrium, the macroporous acid resin K-2631 (Bayer) was used as the catalyst. Equilibrium constants and standard enthalpies, free ene rgies, and entropies for addition of methanol to 2-methyl-1-butene and 2-methyl-2-butene (forward reactions) were determined as a temperatur e function and compared with literature data. The UNIFAC estimates of activity coefficients were used to describe the liquid-phase non-ideal ity.
