Abstract:

The kinetics of Perkin reaction catalyzed by basic catalysts for synthesizing α-furylacrylic acid was inves-tigated by means of the ultraviolet spectr0photometry,verifying a nearly one-order total reaction for each reactant.Th e formation mechanism of acetic anhydride carbanion in the Perkin reaction for synthesizing α-furylacrylic acid was then proposed.It is concluded that acetic anhydride carbanion is obtained from the acetic anhydride with enol form . It is also concluded that the reaction rate is greatly afected by the basicity and structure of catalysts and bv the solvent’s polarity and capability of form ing hydrogen bonds as well

Key words: α-furylacrylic acid, Perkin reaction, kinetics, reaction mechanism
