| titleOfInvention | Method for producing anthraquinones using 1,4-naphthoquinone and 1,3-butadiene |
| abstract | In the present invention, 1,4-naphthoquinone and 1,3-butadiene are subjected to the [2 + 4] Diels-Alder reaction using nitrobenzene as a reaction solvent and an oxidizing agent, followed by continuous oxidative dehydrogenation. The present invention relates to a method for producing anthraquinones.n n n 1,3-butadiene, isoprene and 2,3-dimethyl-1,3-butadiene were used as 1,3-butadienes used in the present invention. Nitrobenzene was used in a molar ratio of 2 to 10 with respect to 1,4-naphthoquinone, [2 + 4] Diels-Alder reaction temperature was 100-150 ° C, and oxidative dehydrogenation reaction was in the range of 160-210 ° C. . In the present invention, the yield of anthraquinones was 90% or more. |
