Product properties & Features

Cinnamic acid, also known as cinnamic acid, benzylacetic acid, 3-phenyl-2-acrylic acid, is an unsaturated aromatic acid with a slight cinnamic odor. It is present as free or ester in imbalsam, cassia oil, and coca leaves. Due to the existence of double bonds, there are cis and trans isomers of cinnamic acid, and three isomorphic polycrystals in the cis form. Both cis and trans exist in nature. Trans exists in Suhe balm, cinnamon oil, Peruvian balm, basil oil and cocoa leaf, and cis exists in Malacca ginger oil. Trans is more stable than cis, and most of the products on the market are trans. Relative molecular mass 148.17. The first crystal form of cis-form is called allocinnamic acid, which precipitates from water as monoclinic crystal system, colorless to white prismatic crystal; Relative density 1.284(4℃); Melting point 42℃; Boiling point 265℃(decomposition), 125℃(2.533×103Pa); Slightly soluble in water (0.937 at 25℃), easily soluble in ethanol, ether and ethyl acetate. The second crystal form is called α-iso-cinnamic acid; The Chemicalbook is monoclinic crystal system, colorless to white prismatic crystal. Melting point 58℃; Boiling point 265℃; Soluble in ethanol, acetic acid, chloroform and acetone, easily soluble in ether. The third crystal form is called β-iso-cinnamic acid; Monoclinic crystal system colorless to white prismatic crystals; Melting point 68℃; Soluble in ethanol, ether, acetic acid, chloroform and acetone. The trans body precipitated from dilute ethanol is monoclinic crystal system, white to yellowish prismatic crystal, relative density 1.2475(4℃), melting point 133℃, boiling point 300℃, very slightly soluble in water (0.1 at 25℃, 0.588 at 98℃), soluble in ethanol (23 at 25℃), chloroform (5.9 at 15℃). Soluble in benzene, ether, acetone, glacial acetic acid and carbon disulfide. Distillation at 140℃ decarboxylated into styrene (polystyrene), oxidation to benzoic acid. Both positive and negative isomers have honey flower aroma and sweet and spicy flavor. Rat transoral D502500mg/kg. The above information has been compiled by Andy at ChemicalBook.

 

Application

Cinnamic acid is an important organic synthesis raw material, mainly used in the synthesis of methyl cinnamate, ethyl cinnamate, benzyl cinnamate, widely used in spice industry and medicine industry. Used medically as an insect repellent. Cinnamic acid is used as a spice to prepare cherry, apricot, honey and cinnamon flavor; It can also be used as the raw material of cinnamate ester. Chinese GB2760-1996 regulation of cinnamic acid as permitted edible spices; In addition, it can also be used as the raw material of photosensitive resin polyvinyl cinnamate series; Chemicalbook into methyl ester, ethyl ester and benzyl ester, which as a fragrance can be used in cosmetics, soap, but also used as a local anesthetic, hemostatic agents and medicine (lactate cardiodine and chlorphenaminobutyrate, etc.) raw materials; Cinnamic acid is also used as plant growth regulators and fungicides and other pesticide raw materials; Preservatives for fruits and vegetables; Used as raw material for UV agent and photosensitive resin, sunscreen cream for cosmetics. Cinnamic acid can also be used as a standard for organic microanalysis of double bonds, determination of uranium and vanadium, separation of thorium, etc.
