Chemische Eigenschaften
trans-Cinnamaldehyde is the main component of cassia oil (about 90%) and Sri Lanka cinnamon bark oil (about 75%). Smaller quantities are found in many other essential oils. In nature, the trans-isomer is predominant.
trans-Cinnamaldehyde is a yellowish liquid with a characteristic spicy odor, strongly reminiscent of cinnamon. Being an ??,??-unsaturated aldehyde, it undergoes many reactions, of which hydrogenation to cinnamic alcohol, dihydrocinnamaldehyde, and dihydrocinnamic alcohol is important. Cinnamic acid is formed by autoxidation.
On an industrial scale, cinnamaldehyde is prepared almost exclusively by alkaline condensation of benzaldehyde and acetaldehyde. Self-condensation of acetaldehyde can be avoided by using an excess of benzaldehyde and by slowly adding acetaldehyde.
Cinnamaldehyde is used in many compositions for creating spicy and oriental notes (e.g., soap perfumes). It is the main component of artificial cinnamon oil. In addition, it is an important intermediate in the synthesis of cinnamic alcohol and dihydrocinnamic alcohol.
Chemische Eigenschaften
Combustible, yellowish, oily liquid (thickens on exposure to air). Strong pungent, spicy, cinnamon odor.
Chemische Eigenschaften
CLEAR YELLOW LIQUID
Verwenden
trans-Cinnamaldehyde is used in the flavor and perfume industry. It is also used in medicine. It reacts with glutathione to get an adduct 1'-(glutathion-S-yl)-dihydrocinnamaldehyde. It is used to prepare cinnamylidene-bisacetamide by reacting with acetamide. Further, it inhibits xanthine oxidase.
Verwenden
Buildingblock - Cinnamaldehyde is an unsaturated aldehyde so it can easily react to many different compounds to be used in a wide range of fragrance compositions. It is also a building block for several agrochemicals (miticides) or for derivatives like cinnamic alcohol, 3-phenylpropanol, cinnamonitrile, 3-phenylpropionylaldehyde (fragrances and as an alternative to enalapril, lisinopril and ramipril).

Inkompatibilitäten
Aldehydes are frequently involved in selfcondensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, ketones, azo dyes, caustics, boranes, hydrazines
Waste disposal
Incineration. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
