Category	Description (English Translation)
Uses & Synthesis Methods Chemical Properties: Yellow crystals (from water) or needle-like crystals (from ether). Melting point: 32°C, boiling point: 53°C / 53.3 Pa. Volatilizes with steam. Uses: Intermediate for vitamin E acetate. Production Method: 1,2,4-Trimethylbenzene is sulfonated with concentrated sulfuric acid to give 2,4,5-trimethylbenzenesulfonic acid, which is then nitrated with potassium nitrate and concentrated sulfuric acid to yield potassium 2,4,5-trimethyl-3,6-dinitrobenzenesulfonate. This is reduced to 2,3,5-trimethyl-p-phenylenediamine dihydrochloride, which is subsequently oxidized with sulfuric acid and sodium dichromate to afford the title compound.
