| titleOfInvention | A kind of preparation method of anisyl propionaldehyde |
| abstract | The preparation method of a kind of anisyl propionaldehyde of the present invention, joins halogen acids in anise alcohol, stirring reaction 1～3h at a temperature of 5 20 DEG C；Solvent, the alkali of powdery and phase transfer catalyst are joined in reactor, in reactor, is slowly added to halogenide and propionic aldehyde, react 12～16h at 60 110 DEG C, available product.The present invention is with commercially available anise alcohol as raw material, and anise alcohol and halogen acids react and obtain methoxybenzyl halogen, then by obtain to methoxybenzyl halogen and propionic aldehyde, alkali is made with the sodium hydroxide of powdery, make solvent with toluene, utilize the action-reaction of phase transfer catalyst, obtain product anisyl propionaldehyde.The method of the present invention is economic and environment-friendly, it is not necessary to high pressure reactor and use noble metal catalyst, low cost, simple to operate, reaction condition is easily achieved. |
