| titleOfInvention | A kind of production method of sorbic acid continuous condensation reaction |
| abstract | The invention discloses a production method for continuous condensation reaction of sorbic acid, and the main points of the technical scheme are as follows: S1, using a batching tank to perform batching, and the added raw materials include toluene, crotonaldehyde, a catalyst, and a recovered solvent; S2, The raw material is sent to the recovery tower by using a flow meter and a pump, and the liquid to be reacted is transferred to the absorption tower by the recovery tower; S3, the ketene gas is added to the absorption tower for reaction, and part of the unreacted ketene gas is sent back to the recovery tower tower; S4, use the reaction kettle to receive the reaction product in the absorption tower; S5, use the pump and pipeline to absorb the reaction product from the reaction kettle, and use the online detector installed on the pump inlet pipeline to detect the sorbic acid polymerization solution, The pump is connected with two outlet pipelines respectively installed with flowmeters, and the DCS automatic control system is used to control the production volume and the feed volume and make them equal, so as to realize the continuous progress of the polymerization reaction. |
