Tolidone, also known as ortho toluidine or diaminodimethylbiphenyl, is a white to slightly red leaf shaped crystal that is soluble in alcohols, ethers, and dilute acids, slightly soluble in water, and has an aniline like odor.
O-Tolidine is mainly used as a dye intermediate. It is also used in the production of naphthol AS-G, direct dark green 2B-NB, direct deep brown B-NM, direct yellow brown ND3G, direct black NBN, and various organic pigments. Zinc powder (or silicon iron powder) is used to reduce o-nitrotoluene to 2,2 ‘- dimethylsymmetric diphenylhydrazine in sodium hydroxide medium, and then rearranged to obtain.
O-Tolidine is substantially used as a color intermediate in the product of naphthol AS- G, direct dark green 2B NB, direct deep brown B- NM, direct unheroic brown ND3G, direct black NBN, and colorful organic colors.
O-Tolidine used in the color assiduity as logical reagents, adsorption pointers, and oxidation- reduction pointers Photometric determination of gold, cerium, and free chlorine.
Measure nitrate, manganese, nitrite, chromium, bobby, cobalt, mercury, and cyanide ions in the air. The logical standard is a sensitive colorimetric photosensitive system for determining gold and free chlorine.
Ortho toluidine is extensively used in the manufacturing of colorings, especially in the product of answerable azo colorings and undoable colors in the cloth, leather, and paper diligence. In addition, it’s also used as a sensitive colorimetric reagent for assaying gold and free chlorine in water.
3,3 ‘- Dimethylbenzidine is used to prepare polyimide and epoxy resin materials.
