Physical properties
colourful green light blue. Bronze powder. In 20 ℃ water solubility of 40 g/L, solubility effected by temperature is very small, water solution is green light blue.
Uses
The strong sulfuric acid for wine, diluted into a red light blue. In aqueous solution of sodium hydroxide to join a blue-black precipitation. For green light blue dye acrylic colourful, tungsten light in more green. In 120 ℃ high temperature dyeing, color is green. Copper ions in dyeing color shade significant turn green in colour and lustre of iron ion in the dark. Compatibility value is 3.5, the f value is 0.31. For wool/nitriles, stick/acrylic blended fabric graft copolymerization dyeing, also can be used for direct printing acrylic carpet.

Synthesis
Stir a mixture of 3-(dialkylamino)phenol (20 mmol) and NaOH (20 mmol) in MeCN (30 mL) for 1 h. Add methyl p-toluenesulfonate (20 mmol) to the mixture.
Stir the reaction mixture at 40 °C for 4 h.
Filter and wash the mixture with MeCN. Evaporate the filtrate. Dissolve the residue in 5% HCl (60 mL) and wash with Et2O (2 x 20 mL). Add K2CO3 slowly to basicify at about pH 9.
Extract the water solution by Et2O (3 x 30 mL). Wash the organic layer with 1 N NaOH solution (2 x 20 mL) and NaCl solution (4 x 30 mL). Dry the organic layer over Na2SO4. Evaporate the solvent to obtain N,N-diethyl-3-methoxyaniline.
