Cinnamic acid is a central intermediate in the biosynthesis of myriad natural products include lignolsto lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. Its biosynthesis is performed by action of the enzyme phenylalanine ammonia-lyase (PAL) on phenylalanine.
Cinnamic acid is a precursor for the synthesis of a huge number of plant substances, including lignin, tannins, flavonoids, pigments, many of the flavor components of spices, and various alkaloids, such as morphine and colchicine.

Preparation
The aqueous solution of hydroxylamine hydrochloride and sodium carbonate was prepared by mixing anhydrous sodium carbonate, hydroxylamine hydrochloride and water. Then the aqueous solution of hydroxylamine hydrochloride and sodium carbonate was added to the solution of cinnamaldehyde and ethanol or methanol, stirred and set it well. Then the reaction mixture was poured into the ice water until the white precipitate was precipitated, the white precipitate was filtered out and washed with water, then the cinnamaldehyde oxime was obtained after drying. Acetic anhydride of 2o 2.5 times (mole ratio) was dripped into cinnamaldehyde oxime, stirred for dehydration and cooled, then vacuum distillation was used to recover acetic anhydride and acetic acid produced by the reaction, and then vacuum distillation was carried out. Cinnamonitrile was obtained by collecting stable fractions at 130C / 2064pa or 151.0 / 5330pa. The method has the advantages of simple operation, low raw material, no pollution and high yield.
