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. |
|
Kjemiske egenskaper |
Det ser ut som hvitt til litt gul krystall med kirsebær og duftende ester duftende {gass. Det har et smeltepunkt på 34 ° C, et kokepunkt på 260 ° C, en brytningsindeks (nD20) på 1.5670 og relativ tetthet (d435) på 1.0700. Det er løselig inetanol, eter, glyserol, propylenglykol. Den eksisterer hovedsakelig i ikke-flyktig olje og mineralolje, uoppløselig i vann. |
|
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%. |
|
Kjemiske egenskaper |
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. |
|
Kjemiske egenskaper |
Metylkanel har en fruktig, balsamisk lukt som ligner på jordbær og en tilsvarende søtsmak. |
|
Kjemiske egenskaper |
White to light yellow fused crystalline mas |
|
Bruker |
