Abstract
The invention discloses a non-phenol basic violet synthetic process which comprises the following steps: mixing an N,N-dimethylaniline compound with water to form a solution; using copper salt as a catalyst and carrying out emulsification by a compound non-ionic emulsifier; performing an oxidation reaction on a system at a temperature of 50 to 80 DEG C; then processing an oxidized material according to a solvent method to obtain high-purity basic violet with low copper content. The non-phenol basic violet synthetic process disclosed by the invention has the advantages of being simple in process, mild in reaction conditions and free of drainage of a great volume of waste water, and has yield of 95 percent or higher.
Description
Technical field
