The conversion of methylpyridines on melted and solid-state alkaline catalysts was studied over the temperature range 430-720 degreesC. It was shown that melted catalysts are preferable for use in the oxidative coupling of methylpyridines. The melt NaOH + 10 wt % V2O5 turned out to be the most selective catalyst in the dimerization reaction of methylpyridines.
