Benzyl cinnamate - 2

Use of Benzyl Cinnamate:


Benzyl cinnamate is used as an ester synthetic perfume, mainly used as a deodorant for oriental essence and artificial cologne, and also as a soap fragrance. Used as a UV absorber. Mainly used in sunscreen and tanning cosmetics. The maximum absorption wavelength for ultraviolet light is 310 nm. The amount added is usually less than 5%. It is used in the flavoring formula, and is usually used to blend fruity flavors such as apricot, cherry and pineapple.


Synthesis of Benzyl Cinnamate


The esterification method and the condensation method are mainly employed:  The esterification method is obtained by neutralizing sodium cinnamate as a raw material and then esterifying with chlorotoluene. The condensation method is obtained by condensation reaction using benzyl acetate and benzaldehyde as raw materials. Natural matter extraction method: The natural substance extraction method is obtained by extracting benzyl cinnamate present in Peru balsam, tolu balsam and benzoin by extraction. Direct esterification of cinnamic acid and benzyl alcohol: transesterification using benzyl alcohol and methyl cinnamate: method of interaction between sodium cinnamate and benzyl chloride: Claisen condensation by benzyl acetate and benzoic acid.
