Method for producing 1-nitroanthraquinone |
| abstract |
(57) [Summary] [Object] To provide a method for producing 1-nitroanthraquinone, which comprises nitrating anthraquinone without using an expensive catalyst and without producing a large amount of waste acid. [Constitution] Anthraquinone is an inorganic protic acid such as sulfuric acid, At least one selected from an inorganic protonic acid anhydride such as sulfur trioxide and an inorganic protonic acid anhydride adduct such as chlorosulfonic acid is used as a catalyst, and nitrogen oxide and oxygen-containing ozone or air are allowed to act. A method for producing 1-nitroanthraquinone, which comprises nitrating. |
