[General Description]

4-Ethylpyridine undergoes metal-ligand interaction with Zn-porphyrin which can be studied by mass spectrometry.
[Purification Methods]

Dry 4-ethylpyridine with BaO, and fractionally distil it. Also purified by converting to the picrate, recrystalising and the free base is regenerated and distilled. [Beilstein 20/6 V 10.]
