| titleOfInvention | Method for preparing raspberry ketone under supercritical condition |
| abstract | The invention discloses a method for preparing raspberry ketone under supercritical condition, which comprises the steps of taking p-hydroxybenzaldehyde and acetone as raw materials, taking an aromatic hydrocarbon solvent as a solvent, continuously carrying out condensation reaction in a pipeline type reactor, obtaining p-hydroxyphenyl butenone under the condition of not adding a catalyst, and then carrying out hydrogenation reduction reaction on a methanol solution of the p-hydroxyphenyl butenone and hydrogen in a kettle type reactor under the action of a nickel catalyst to generate the raspberry ketone. The preparation method solves the problem of environmental protection, has the advantages of simple process, no need of acid or alkali catalyst, less three wastes, high yield and easy amplification, and has higher industrial application value. |
