Determination of Cinnamaldehyde Oxidation Products by Multi-order Ultraviolet Derivative Spectrometry
In order to monitor the oxidation of cinnamaldehyde under normal temperature and pressure,the ultraviolet spectra of cinnamaldehyde and its oxidation products,cinnamic acid,benzaldehyde and benzoic acid were treated with third derivatives processing.The results indicated that one-derivative peak for benzaldehyde,the second-derivative peak for cinnamic acid and the third-derivative peak for benzoic acid and cinnamaldehyde respectively had a good linear relationship with its mass concentration.Therefore,this methed can be used for rapid determination of cinnamaldehyde oxidation process.
