| titleOfInvention | Synthesis method of 2-ethylanthraquinone |
| abstract | The invention discloses a synthesis method of 2-ethylanthraquinone, which comprises the following steps: gasifying 2-(4-alkylbenzoyl)benzoic acid in a gasification chamber under reduced pressure while controlling the temperature at 230-370 DEG C; carrying out gasification reaction on the 2-(4-alkylbenzoyl)benzoic acid reactant in the gaseous form through a catalyst bed composed of acidic molecular sieves, wherein the temperature of the reactor is controlled at 220-350 DEG C, the reaction time is 10-240 seconds, and the reaction pressure is 5-20 mmHg; and cooling the reaction product, extracting, washing with alkali, washing with water, and distilling to obtain the 2-ethylanthraquinone. The detailed method is disclosed in the specification. The invention has the advantages of clean production, no generation of waste acid and pollutants, high yield and stable product quality, and is simple to operate; and the conversion rate of the reactant 2-(4-alkylbenzoyl)benzoic acid can reach 90% above, and the purity of the product 2-ethylanthraquinone can reach 98.5% above. |
