white monoclinic crystal, with slightly cinnamon flavor. Molecular weight 148. 17. It has cis-and trans-isomers. Natural cinnamic acid is mainly found in plant essential oils such as styromatic oil, cinnamon oil, Peru balsam oil and basil oil, and natural products are usually trans. The melting point of trans-cinnamic acid is 133 ℃, the boiling point is 300 ℃, the flash point is 100 ℃, and the relative density is 1. 2475. Cinnamic acid soluble in ether, acetone, acetic acid, chloroform and other organic solvents, difficult to dissolve in cold water, soluble in hot water.
isolated from Styrax or other plant essential oils containing cinnamic acid.
mainly used in the preparation of flavor.
