Janus Green B Chemical Properties,Uses,Production

Chemical Properties

green powder

Uses

As dye for cotton, wool; as biological stain; in electrodeposition of copper, Brown, Fellows, US 2882209 (1959 to Udylite Res. Corp.).

Safety Profile

Poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion, skin contact, subcutaneous, and intramuscular routes. Human systemic effects by inhalation: nausea or vomiting. A skin and severe eye irritant. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.

Purification Methods

The dye dissolves in H2O to give a bluish violet solution which becomes colourless when made 10M in NaOH. It dissolves in EtOH to give a blue-violet colour, filter from insoluble material, then add dry Et2O whereby the dye separates out leaving a small amount of blue colour in solution. Filter off the solid and dry it in a vacuum. Store it in a dark bottle. [Colour Index Vol 4, 3rd edn, 4015 1971.]
