ABSTRACT:
Alkali metal salts of carbazole are prepared by heating carbazole and alkali metal hydroxides with stirring in an organic solvent which forms an azeotrope with water, and removing the resulting water as an azeotrope from the reaction system.
The resulting alkali metal salts of carbazole are useful as a material for the preparation of vinyl carbazole for use in electrophotography. The reaction is promoted particularly by the presence of a small amount of water in the reaction system prior to heating.
