2-Ethylanthraqunione was prepared by cyclization from 2-(4-ethylbenzoyl) benzoic acid in 1,2-dichloroethane with 20% fuming sulphutic acid as catalyst. The influences of solvent quantity,ratio of 2-(4-ethylbenzoyl) benzoic acid and fuming sulphutic acid, reaction time on the yield of 2-ethylanthraquinone were discussed.
