| titleOfInvention | A kind of preparation method of high-purity tetramethylbisphenol A |
| abstract | The invention discloses a preparation method of high-purity tetramethylbisphenol A. The preparation method of this high-purity tetramethylbisphenol A includes the following steps: 1) in the reactor, heating 2,6-xylenol to a molten state, then adding an organic carboxylic acid catalyst, and mixing and stirring; 2) continuing Add organic sulfonic acid catalyst, then add acetone, and react to obtain slurry; 3) transfer the slurry to a kneader, stir to obtain a paste product; 4) transfer the paste product to a stirrer, add an organic solvent for washing, filter, The resulting solid product was dried. The preparation method of the invention can obtain high-purity and high-yield tetramethylbisphenol A with a purity of more than 98.5% and a yield of more than 75%, and has wide application prospects. |
