Abstract

PURPOSE: To obtain the titled compound useful as a raw material for azine dyes and agricultural chemicals in high yield, by dehydrogenating a readily and economically available 1,2,3,4,6,7,8,9-octahydrophenazine in the presence of a dehydrogenating catalyst, e.g. Pd or Pt.
CONSTITUTION: 1,2,3,4,6,7,8,9-Octahydrophenazine obtained by heating bis(2- hydroxyiminocyclohexyl)amine in an aqueous solution in the presence of an acid in high yield and economically is dehydrogenated in the presence of a dehydrogenating catalyst to give phenazine. A nobel metal of Group VIII in the periodic table, particularly palladium or platinum, may be preferred as the dehydrogenating catalyst.
