Abstract
4 : 11 dihydroxy fluoranthene and its dialkyl ethers such as the dimethyl ether are obtained by sulphonating fluoranthene to the disulphonic acid, subjecting the product to alkali fusion and then alkylating. The sulphonation is performed at room temperature. An example is given. Dihydroxy fluoranthene is converted on standing in aqueous caustic soda lye in presence of air, into a quinonoid form, probably by oxidation.
