Cinnamyl alcohol Usage And Synthesis

Uses	Cinnamyl alcohol is valuable in perfumery for its odor and fixative properties. It is a component of many flower compositions (lilac, hyacinth, and lily of the valley) and is a starting material for cinnamyl esters, several of which are valuable fragrance materials. In flavor compositions, the alcohol is used for cinnamon notes and for rounding off fruit aromas.
Preparation	Cinnamyl alcohol is prepared on an industrial scale by reduction of cinnamaldehyde. Three methods are particularly useful: 1) In the Meerwein–Ponndorf reduction, cinnamaldehyde is reduced to cinnamic alcohol (yield about 85%) with isopropyl or benzyl alcohol in the presence of the corresponding aluminum alcoholate. 2) A 95% yield of Cinnamyl alcohol is obtained by selective hydrogenation of the carbonyl group in cinnamaldehydewith, for example, an osmium–carbon catalyst. 3) High yields of Cinnamyl alcohol can be obtained by reduction of cinnamaldehyde with alkali borohydrides. Formation of dihydrocinnamic alcohol is thus avoided.
Chemical Properties	Cinnamyl alcohol has a pleasant, floral odor and bitter taste.
Uses	cinnamyl alcohol is naturally occurring in cinnamon bark, it can also be synthetically manufactured. It is used in cosmetics as a fragrance or flavoring agent.In perfumery; as deodorant in 12.5% solution in glycerol.
Aroma threshold values	Detection: 1 ppm; cis- form, 81 ppb; trans- form, 2.8 ppm
Taste threshold values	Taste characteristics at 20 ppm: green, floral, spicy and honey with a fermented yeasty nuance.
Chemical Synthesis	Obtained originally by saponification of extraction from storax; synthetically, by reduction of cinnamaldehyde with sodium or potassium hydroxide.
Purification Methods	Crystallise the alcohol from diethyl ether/pentane. [Beilstein 6 I 281.]
