Methyl cinnamate Usage And Synthesis


Chemical Properties

It appears as white to slightly yellow crystal with cherry and fragrant ester fragrant {gas. It has a melting point of 34 ° C, a boiling point of 260 ° C, a refractive index (nD20) of 1.5670 and relative density (d435) of 1.0700. It is soluble in ethanol, ether, glycerol, propylene glycol. It mostly exists in non-volatile oil and mineral oil, insoluble in water.
Natural products are contained in basil oil (up to 52%), galangal oil and cinnamon oil.

Preparative Methods

It is obtained by esterification of cinnamic acid with methanol. The mixture of cinnamic acid, methanol and sulfuric acid (or hydrochloric acid) was heated to reflux for 5 h, and the excess amount of methanol was added. Cool and spate the acid layer, washed with water and 10% sodium carbonate solution, and then washed with water to neutral. The crude product was subjected to recrystallization or vacuum distillation [collection of 132-134 ° C (2.0 kPa) fraction] to give methyl cinnamate with a yield of about 70%.

Chemical Properties

Methyl cinnamate has a fruity, balsamic odor similar to strawberry with a corresponding sweet taste. May be prepared by esterification of cinnamic acid with methanol using HCL as catalyst; or by adding HCL to a boiling solution of cinnamyl nitrile in methanol.
