| titleOfInvention | Catalytic reaction rectification production method and device for high-purity natural benzaldehyde |
| abstract | The invention provides a method and a device for a catalytic reaction rectification technology for producing high-purity natural benzaldehyde. A cinnamon oil feeding opening is arranged at the top of a catalytic reaction rectification section; a water steam feeding opening is arranged at the bottom of a catalytic reaction rectification tower; a hydrolysate natural benzaldehyde can be extracted from the tower top of the catalytic rectification tower; and residual oil is discharged out from the tower bottom of the catalytic reaction rectification tower. The method and the device disclosed by the invention are characterized in that reactant raw materials for producing the natural benzaldehyde are cinnamon oil and water. By utilizing the method disclosed by the invention to produce the natural benzaldehyde, cinnamyl aldehyde in the cinnamon oil does not need to be separated and purified, and the cinnamon oil can be directly used as the raw material to react. The method and the device disclosed by the invention have the advantages that two unit operations including a reaction for hydrolyzing the cinnamyl aldehyde to be natural benzaldehyde, and purification, rectification and separation of benzaldehyde are organically coupled in one equipment to be carried out at the same time, so that equipment investment is saved and subsequent operation cost is further reduced. |
