Abstract
The authors studied experimentally the following principle of dyestuff Purification, and obtained satisfactory results in the sense of purity and yield: Forming dye-surface active agent complex longrightarrow dissolving the complex longrightarrow breaking salt linkage of the complex longrightarrow Precipitating dye-Na salt. It was found that dyestuff-Purity was satisfied by once for all purifications and dye Boss was small during the procedure. Also, extensive application was appeared from properly selected solvent and surface active agent.
