That was ?2-Methyl-5-nitrobenzenesulfonie acid?sodium hydroxide solution to the backflow and Benzene-1,4-diamine common heating, its molecular ratio is 2:1. Its product (C.I. Direct Orange 28, C.I. 40065) diazo, and 4-Hydroxy-6-(phenylamino)naphthalene-2-sulfonic acid in alkaline conditions coupled.
Properties and Applications
brown. Soluble in water for the opacity of the yellow light brown, not soluble in ethanol and acetone. The strong sulfuric acid for black purple, for green light brown after diluted. Dyes to dilute sulphuric acid solution turn dark; Add thick sodium hydroxide solution unchanged.
