Manufacturing Methods : commonly known as Aniline Yellow. (a) aniline hydrochloride solution added to a aniline diazonium salt, and slowly, until aniline diazonium salt salt disappear so far. Then in contain a small amount of aniline hydrochloride aniline solution will product (Diazoaminobenzene) 30 ~ 40 ℃ heating 2 ~ 3 hours, acidified to form 4-(Phenyldiazenyl)benzenamine hydrochloride and crystalline precipitates. In order to obtain 4-(Phenyldiazenyl)benzenamine times the company, and then 4-(Phenyldiazenyl)benzenamine hydrochloride dissolved in water and mercerized. (B) aniline diazotization and coupling anilino-methanesulfonic acid, sodium hydroxide solution and then with boiled together, hydrolyzed mesylate.
Properties and Applications: green light yellow to red light yellow. Melting point is 127.5 ℃, its hydrochloride for blue crystal. Soluble in ethanol, slightly soluble in water for yellow. In concentrated sulfuric acid for brown, red after diluted solution; In hydrochloric acid solution for red, boil color disappear. Used for alcohol soluble paint, varnish, paraffin wax, oil, synthetic resin coloring.
