INTERCALATION OF PYRIDINE AND QUINOLINE INTO ALPHA-ZIRCONIUM PHOSPHATE

The uptake of pyridine and quinoline into alpha-zirconium phosphate ha s been investigated by the batch method. The effect of solvent on the reactions was also studied. Pyridine was taken up from ethanol, chloro form, carbon tetrachloride, ethanol-water, and acetone-water solutions , but not from pure acetone at 25 degrees C. Water accelerated the upt ake of pyridine. These facts indicate that a water molecule was involv ed in the uptake reaction of pyridine. Quinoline was taken up easily i n an ethanol-water solution at 25 degrees C, and in an ethanol solutio n at the boiling point. Two reactions-ion exchange and intercalation-o ccur on taking up the quinoline. An IR spectrum of the quinoline form is reported.
