| | 2-PHENYLAZO-4-METHYLPHENOL Usage And Synthesis |
| Preparation | aniline diazotization, and p-Cresol coupling. | | Properties and Applications | green yellow. Soluble in ethanol, Acetone and Benzene for green light yellow, hardly soluble in hot water, not soluble in organic solvent, acid resistance, light fastness is good, the heat resistance is poor. From ethanol in the product melting point of 107 ~ 108 ℃. In concentrated sulfuric acid to red light brown, dilution after yellow brown precipitation; In hot concentrated hydrochloric acid for orange brown solution; Sodium hydroxide in 2% hot liquid for red orange. Mainly used for transparent lacquer, rubber, organic glass, aluminum foil, celluloid and plastic products coloring.
