Abstract
The polymerisate of 4-chloropyridine consists of a mixture of water-soluble substances showing the properties of pyridyl-4-chloropyridinium chlorides. These compounds are rapidly decomposed by water, the chlorine in the pyridine ring being split off hydrolytically. From measurements on the U.V. spectra, it appears that 4-hydroxypyridine and N(4′-pyridyl)-4-pyridone are produced in the hydrolysis of the polymerisate. These compounds were isolated in the form of their picrates. In addition, two other picrates have been isolated, which are in all probability derived from compounds containing more than two pyridine rings.
