| titleOfInvention | A kind of synthetic method of 9,10-anthraquinone |
| abstract | The present invention relates to a method for preparing anthraquinone from 1,3-butadiene and p-benzoquinone. The method comprises two steps. First, 1,3-butadiene and p-benzoquinone are prepared under the action of Lewis acid catalyst or simply Diels-Alder reaction occurs under heating conditions to generate intermediate product A, and then intermediate product A undergoes dehydrogenation reaction under the action of Cu catalyst to generate 9,10-anthraquinone. The dehydrogenation reaction of intermediate product A can be carried out in a fixed bed reaction The intermediate product A is directly injected into the reaction tube, or the anthraquinone is obtained through the catalyst bed under the purging of the carrier gas. The process has simple reaction procedure and high target product selectivity, and provides a new route for preparing anthraquinone from biomass resources. |
