Hemimellitic acid

HemimeUitic acid is not manufactured commercially but is available as a laboratory chemical in a hydrate form (99). Like ttimesic acid, it is formed when coal-like materials are oxidized, but can be synthesized in a purer form by oxidizing hemimeUitene [562-73-8] (1,2,3-trimethylbenzene) or hemimeUitol [526-85-2]. HemimeUitic anhydride can be produced by thermal dehydration of the acid in trichiorohenzene at 261°C (147). Synthesis of hemimellitic acid and anhydride have been described (148). There are no reported uses which ate unique to hemimellitic acid. [Pg.499]

Important derivatives are obtaiaed from PMBs by oxidation (see Phthalic acid and otherbenzenecarboxylic acids). For example, hemimellitene is oxidized to hemimellitic acid dihydrate [36362-97-7] or hemimellitic acid [569-51-7] which can be dehydrated to hemimellitic anhydride [3786-39-8]. [Pg.510]
