| titleOfInvention | A kind of 2 based on supercritical fluid technique, the production method of 4,6- trimethylpyridines |
| abstract | The present invention provides a kind of 2 based on supercritical fluid technique, the production method of 4,6- trimethylpyridines, the following steps are included: catalyst and acetone are added in supercritical reaction kettle, it stirs evenly, liquefied ammonia is pressed into reaction kettle, first pressurized, heated makes liquefied ammonia reach the state of boundary over zero, being further continued for pressurized, heated makes acetone reach the state of boundary over zero, it is quickly cooled down cooling, reaction is terminated, obtains 2 based on supercritical fluid technique, 4,6- trimethylpyridine first products；Or acetone is added in supercritical reaction kettle, liquefied ammonia is pressed into reaction kettle, first pressurized, heated makes liquefied ammonia reach the state of boundary over zero, being further continued for pressurized, heated makes acetone reach the state of boundary over zero, it is quickly cooled down cooling, reaction is terminated, obtains 2 based on supercritical fluid technique, 4,6- trimethylpyridine first products；2,4,6- trimethylpyridine first products are finally obtained into 2 based on supercritical fluid technique, 4,6- trimethylpyridines by rectification.Preparation method of the present invention is simple, and reaction is efficient, the yield and purity is high of product. |
