Intercalation of pyridine and quinoline intoα-zirconium phosphate

Abstract

The uptake of pyridine and quinoline intoα-zirconium phosphate has been investigated by the batch method. The effect of solvent on the reactions was also studied. Pyridine was taken up from ethanol, chloroform, carbon tetrachloride, ethanol-water, and acetone-water solutions, but not from pure acetone at 25°C. Water accelerated the uptake of pyridine. These facts indicate that a water molecule was involved in the uptake reaction of pyridine.Quinoline was taken up easily in an ethanol-water solution at 25°C, and in an ethanol solution at the boiling point. Two reactions — ion exchange and intercalation — occur on taking up the quinoline. An IR spectrum of the quinoline form is reported.
