Cinnamic acid is an organic compound with the formula C6H5CH=CHCOOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants. It exists as both a cisand atransisomer, although the latter is more common. 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.

In the international market, it is mainly used in perfumes and sunscreens. China's GB-2760-2014 stipulates that they are allowed to be used as edible spices. It is used as a scenting agent in the spice industry. It is often used to mix oriental flower flavors such as carnations, cherries, strawberries and grapes. It is also used in soaps, detergents, and flavors and cakes. Both methyl cinnamate and ethyl cinnamate can be added to cigarette shreds and used as flavor enhancers and flavor compensators. As an organic synthesis intermediate, it is mainly used in the pharmaceutical industry. The medicinal value of methyl cinnamate: Imidazole and methyl cinnamate use methyl as an intermediate linker to prepare methyl p-bromomethylcinnamate. This intermediate is the main raw material for the production of ozagrel. Methyl cinnamate has a positive effect on the suppression of vitiligo. In whitening and sun protection, the effect of methyl cinnamate is obvious.

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.
