| titleOfInvention | Organic synthesis intermediates anthraquinone synthesis method |
| abstract | The present invention discloses organic synthesis intermediates anthraquinone synthesis method, comprises the following steps: 9-hydroxy-10-methoxyanthracene, toluene solution are added in the reaction vessel, controls the temperature of the solution, reacts, adds sodium sulfate solution, controls the stirring speed; then dodecanoyl tetra iridium powder is added, the octadecenoate solution is added in batches, controls the solution temperature, continues to react, reduces the temperature, refluxes, potassium chloride solution is added, precipitates the solid, washed with o-dichlorobenzene solution for several times, washed with methylamine solution for several times, recrystallized from the nitrobenzene solution, dehydrated with dehydration, gets the finished product anthraquinone. <Figure 1> |
