3,4,5,2',3',4'-Hexahydroxybenzophenone - Reference Information
| use | thinking enhancer. Used for Alzheimer's disease and Parkinson's disease. |
| production method | 16g gallic acid, 20g phloroglucinol, 35g anhydrous zinc chloride and 100ml phosphorus oxychloride were reacted at 55~60 ℃ for 2.5h. Below 20 ℃, slowly pour into 1L of ice water. After standing for 2h, filter, wash with water (2 × 150 m1), 1% sodium bicarbonate (2 × 50 m1) and water (3 × 100 m1) to a Ph value of about 5. Dissolve 150ml of 95% ethanol, decolorization and filtration with activated carbon. Add 150ml of water and place at 10 ℃ for 4 hours. Filtration, small amount of deionized water washing, drying to obtain epicenzophenone, the yield is 49.1%. |
