Toxicity |
Moderately toxic by ingestion . The oral LD50 for rats is 2610 mg / kg . It is combustible as a liquid, and when heated to decomposition it emits acrid smoke and irritating fumes. |
|
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. |
|
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. |
