Jq. Lin et al., Necessary and sufficient conditions for reactive azeotropes in multi-reaction mixtures in terms of elemental composition, CHIN J CH E, 8(4), 2000, pp. 361-365
Necessary and sufficient conditions for azeotropy in reactive mixtures are
derived in terms of elemental composition, which shows that in the space of
elemental compositions, they take the same functional form as the conditio
ns for azeotropy in non-reactive mixtures. The production of methyl tert-bu
tyl ether (MTBE) is taken as an example. It is found that there are a "pseu
do" intermediate-boiling ternary reactive azeotrope at p = 101.325 kPa and
two "real" ternary reactive azeotropes at p = 101.325 Pa. The introduced el
emental compositions also reduce the dimensionality of the phase diagrams a
nd provide a natural set of variables for visualization of phase behavior.
