| titleOfInvention | Raspberry ketone reaction device and raspberry ketone continuous preparation method |
| abstract | The invention discloses a raspberry ketone reaction device and a raspberry ketone continuous preparation method.4-formyl phenol sodium solution and acetone are used as raw materials, water is used as a solvent, and continuous aldehyde ketone condensation reaction is carried out in a microreactor to obtain 4- (3-oxo-1-butylene) phenol sodium salt water solution; the intermediate solution is not separated, after a catalyst is added, the intermediate solution continuously reacts with hydrogen in a tubular reactor with a propelling propeller to selectively reduce olefin to obtain an aqueous solution of raspberry ketone sodium salt, and the aqueous solution of raspberry ketone sodium salt is subjected to post-treatment operations such as neutralization and crystallization to obtain raspberry ketone; in the synthesis process, only water is used as a solvent, so that the safety of catalyst separation is improved, the selectivity of the product is up to 99%, and the generated raspberry alcohol is less than 0.2% due to over reduction; the reaction system has no amplification effect, has the characteristic of good stability of continuous reaction, has the advantages of simple and convenient operation, short production period, simple production process, less pollution, low energy consumption and the like, and is suitable for industrial production. |
