Solvent Green 1

blue green in water, blue green in ethanol, yellow in concentrated sulfuric acid, dark orange after dilution. When sodium hydroxide is added into the dye aqueous solution, there is a gray green precipitate. 

Method: (a) benzaldehyde (1 mole) is condensed with N, N-dimethylaniline (2 mole) in the presence of hydrochloric acid or sulfuric acid, and then the product is oxidized with lead peroxide and acid, and then the free alkali is made; (b) n, N-dimethylaniline is heated with trichlorotoluene, and then the free alkali is made
