Manufacturing Methods : (a) will Sodium nitrite (1 Moore) to join O-Methylaniline (8.5 Moore) and hydrochloric acid (1 Moore), the temperature is maintained at 28 ℃ below, until diazotization finish. Add a small amount of hydrochloric acid (about 0.2 Moore), and heating (40 ℃, 3 hours), in order to separate, with Sodium hydroxide for mercerization, and distillation reservoir. In order to get the refined products, usable alcohol recrystallization; (b) O-Methylaniline diazotization, and O-Methylaniline base Methanesulfonic acid coupling, and then with Sodium hydroxide solution common boiling, hydrolysis off Methanesulfonic acid base.

Properties and Applications:  yellow. In the ethanol for yellow sheet crystallization, melting point 100 ℃. Soluble in Acetone, ethanol, Cellosolve and Toluene, insoluble in water. In concentrated sulfuric acid for brown, dilution after red orange solution, and precipitation; In concentrated nitric acid for red brown solution; In concentrated hydrochloric acid partly dissolved for brown; In 10% of the sulfuric acid insoluble; In 10% Sodium hydroxide solution slightly soluble, pale yellow. Dye alcohol solution to join hydrochloric acid red hydrochloride crystal, heating the solution. Used for paraffin color.
