How much cinnamaldehyde is in cinnamon?
The major componant of oil of cinnamon is cinnamaldehyde (70–80%). Cinnamaldehyde is classified as an aromatic aldehyde—it contains an aldehyde functional group and has a benzene (aromatic) ring (see Figure 1).
Is cinnamaldehyde a cinnamon?
The most important constituents of cinnamon are cinnamaldehyde and trans-cinnamaldehyde (Cin), which are present in the essential oil, thus contributing to the fragrance and to the various biological activities observed with cinnamon [4].
How is cinnamaldehyde prepared?
Cinnamaldehyde is prepared in one step by the oxidation of cinnamyl alcohol using PCC [pyridinium chlorochromate (C5H5NH+ CrO3Cl-)] as the oxidizing agent in DCM (dichloromethane). The reaction system is subjected to reflux & stirring (using a magnetic bar) for about 20 minutes.
Why is cinnamaldehyde not soluble in water?
Cinnamaldehyde not miscible with water because the majority of the molecule is non-polar, and only a small portion is polar, the hydroxyl group. This means that the molecule is not able to interact with water and H-bond or have a dipole- dipole moment making it insoluable in water.
Is cinnamaldehyde soluble in water?
The water solubility of cinnamaldehyde is quite low (1.35 g L–1), (62) which sometimes limits its applications.
What is the solubility of cinnamaldehyde in water?
1.35 g L–1
The water solubility of cinnamaldehyde is quite low (1.35 g L–1), (62) which sometimes limits its applications.
Is cinnamaldehyde a liquid?
Cinnamaldehyde, or 3-phenylprop-2-enal to use its IUPAC name, is an oily yellow liquid at room temperature with a boiling point of 246 °C. Cinnamaldehyde can be made synthetically but is more commonly obtained from the steam distillation of the oil of cinnamon bark which is a much more efficient process.
