    Abstract: Production of auramine salts and auramine salt solutions from 4,4''-bisdimethylaminodiphenylmethane or 4,4''bisdiethylaminodiphenylmethane in the presence of sulfur and urea by reaction of the components, with or without the addition of an ammonium salt, taking up the auramine base in a solvent which is not miscible with water and extracting the auramine base by reaction with an acid in water, formamide or glycol with the formation of a salt. The auramine salts and auramine salt solutions obtained are outstandingly suitable for the production of dye liquors.
