| titleOfInvention | Hydroquinone preparation method |
| abstract | The invention relates to a hydroquinone preparation method, in particular to a method for producing hydroquinone by means of catalytic hydrogenation and reduction of benzoquinone. The method includes: adding hydrogenation aqueous suspension into a closed reaction kettle, feeding inert gas into the reaction kettle to replace the air out of the reaction kettle, adding palladium carbon catalyst into the reaction kettle, controlling hydrogen pressure in the reaction kettle and the reaction temperature while stirring the reaction liquid, and obtaining the hydroquinone with the purity equal to or higher than 99.0% after reaction. The hydroquinone preparation method is simple in operation, low in reaction condition, low in raw material loss and applicable to industrial production. |
