Abstract

2,21-Dipyridyl is manufactured by heating pyridine with ferrous chloride under superatmospheric pressure. The preferred temperature range for carrying out the reaction is 250 DEG -350 DEG C. The preferred molar ratio of pyridine to ferrous chloride is between 3 to 1 and 25 to 1. The ferrous chloride may be in a hydrated form or may be anhydrous or it may be used as a ferrous chloride-pyridine complex. Specification 785,732 is referred to.
