| Questions And Answer | Back Directory | [Preparation]
Using p-methylbenzaldehyde as a raw material and alcohol as a reaction solvent, the reaction is carried out under nitrogen protection in the presence of sodium alkoxide and/or sodium alkoxide alcohol solution and acetate under heating conditions. After the reaction is completed, the mixture is concentrated to an oily substance, and then an alkaline solution is added to hydrolyze the reaction. Finally, acid is added to adjust the acidity to obtain 4-Methylcinnamic acid. | [Uses]
p-Methylcinnamic acid can be used in cosmetic fragrances and pharmaceutical intermediates. |
