Use | Solvent Orange 45# for alcohol, Ester solvent coloring. Also used in paint, synthetic resin coloring. |
production method | 2-amino-4-nitrophenol and acetoacetanilide are used as raw materials. The former is first diazotized and then coupled to the latter, followed by addition of a cobalt complexing agent to complex the product. The final product was obtained by filtration, drying and pulverization.. |
