化学的特性
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.
使用
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.
定義

不和合性
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
