Oil Orange;C.I.Solvent Orange2
Molecular formula :
MW :

nature : also known as oil-soluble yellow. Look for the yellow powder, melting point of 131 ° C, in acetic acid analysis for the red crystal. Micro-soluble ethanol, acetone, benzene and nitric acid. Concentrated sulfuric acid soluble red to purple, said after the release into a big red to orange-red precipitation; The concentrated nitric acid solution for the red, orange become diluted. The ethanol was orange red, diluted hydrochloric acid solution encountered a slight change to the case of sodium hydroxide brown-orange. Used mainly petroleum products, educational supplies and ink rendering. From o-toluidine diazotization, with 2-naphthol coupling derived.
