Product Methods of Indigo Carmine.
By bis-dimethylaminodiphenylmethanol and 2-hydroxynaphthalene-3,6-disulfonic acid, in the presence of concentrated sulfuric acid, the loss of a molecule of water condensation colorless parent, in a weak acid solution with manganese dioxide oxidation into triarylmethane pigment.
Diphenylmethanol is obtained by oxidizing tetraalkyldiaminodiphenylmethane with manganese dioxide and sulfuric acid. It can be condensed directly using its centrifugally separated filter cake. Manganese dioxide is freshly prepared from manganese sulfate and potassium permanganate in sodium carbonate solution.
