Interaction of the quinoline bases of coal tar with sulfonic-acid cationites

Interaction of the quinoline bases of coal tar with sulfonic-acid cationites The equilibrium distribution of quinoline, isoquinoline, and quinaldine between aqueous solutions and KU-2-4 and KU-2-8 sulfonic-acid ionites of polystyrene type (counterparts of Dowex 50 × 4 and 50 × 8 ion-exchange resins) in the form of copper and iron cations is considered. The distribution coefficients of each base between the two phases (KU-2-4 cationate and the solution) are calculated. The distribution coefficients of the quinoline between the Cu2+ form of the ionite and the solution differ by a factor of two from those for quinaldine and isoquinoline. Accordingly, the Cu2+ form of KU-2-4 cationite is of interest for the development of ligand-sorptional methods of extracting quinoline from its mixture with isoquinoline and quinaldine, so as to expand the resource base for small-scale chemistry on the basis of coke byproducts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The equilibrium distribution of quinoline, isoquinoline, and quinaldine between aqueous solutions and KU-2-4 and KU-2-8 sulfonic-acid ionites of polystyrene type (counterparts of Dowex 50 × 4 and 50 × 8 ion-exchange resins) in the form of copper and iron cations is considered. The distribution coefficients of each base between the two phases (KU-2-4 cationate and the solution) are calculated. The distribution coefficients of the quinoline between the Cu2+ form of the ionite and the solution differ by a factor of two from those for quinaldine and isoquinoline. Accordingly, the Cu2+ form of KU-2-4 cationite is of interest for the development of ligand-sorptional methods of extracting quinoline from its mixture with isoquinoline and quinaldine, so as to expand the resource base for small-scale chemistry on the basis of coke byproducts.
