What is 2,4-Dimethylaniline-6-sulfonic acid?
Production Methods
Production is from 4-amino-1,3-dimethylbenzene (m-xylidine) and 96 % sulfuric acid by baking the sulfate paste in vacuo, subsequently purifying the product with boiling milk of lime, and finally precipitating the sodium salt with sodium chloride. 2-Amino-3,5-dimethylbenzenesulfonic acid can also be produced by sulfonation of m-xylidine in 1,1,2,2-tetrachloroethane with chlorosulfuric acid and subsequent boiling until no more hydrogen chloride is formed.
