Methyl benzoate Usage And Synthesis
  • Flavors and perfumeMethyl benzoate is a commonly used aromatic carboxylic acid esters, flavors, and fragrances in daily chemical industry of China with strong floral, fruity aroma and ylang and tuberose like nuances as well as phenol breath. It is naturally presented in ylang oil, tuberose oil, clove oil, oil of Kalanchoe and daffodils oil and some other kinds of essential oils.
    Methyl benzoate is the food flavors allowed by the provision of the GB2760-1996 of China and can be used for modulation of strawberry, raspberry, cherry, pineapple, rum, vanilla beans and nuts flavor and some other kinds of flavor essence; it can be applied to food and can also be applied to daily flavor formulations for the preparation the base of ylang type and flower flavor type incense with the amount being less than 12%. There is no restriction in IFRA.
    Methyl benzoate was identified as GRAS by FEMA with the FEMA number being 2683 and approved by the FDA for human administration. The Council of Europe has listed methyl benzoate into the table of artificial flavor which can be used for food and is harmless to the human health with the maximum amount being 61 mg/kg and ADI being 5 mg/kg.
    Methyl benzoate is stable in air and can be slowly oxidized in the presence of an oxidizing agent; it can react with base and can subject to saponification with generating benzonic acid. It can also have transesterification to prepare other kinds of benzoates; it is also susceptible to hydrolysis. According to the information provided by RIFM, the acute toxicity data of methyl benzoate: oral LD50: 3.4g/kg (rats).
    The traditional method is based on the esterfication of the benzoate and methanol in the presence of sulfuric acid for generating methyl benzoate. Since the methyl benzoate is the intermediate in the production of polymer material-the by-product of dimethyl terephthalate. Therefore, we can try to isolate and obtain the product which can meet the perfumer specification from the crude methyl benzoate.
    Methyl benzoate can not only be used for the preparation of rosette, geranium type and other flavors but also be used as the solvents of cellulose esters, cellulose ether, resins and rubber; it can also be used for the fiber dyeing of hydrophobic polyester and can shorten the dyeing time, reduce the dyeing temperature and improve the degree of wash fastness after dyeing fabric.

  • DescriptionMethyl benzoate is an organic compound. It is an ester with the chemical formula C6H5CO2CH3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents. Methyl benzoate has a pleasant smell, strongly reminiscent of the fruit of the feijoa tree, and it is used in perfumery. It also finds use as a solvent and as a pesticide used to attract insects such as orchid bees.
  • Chemical PropertiesMethyl Benzoate has been found in essential oils (e.g., ylang-ylang oil). It is a colorless liquid with a strong, dry-fruity, slightly phenolic odor. Methyl benzoate can be converted simply into other benzoates by transesterification. Since methyl benzoate is a fairly large by-product in the manufacture of Terylene, earlier synthetic routes such as those starting from benzoic acid or benzoyl chloride have largely been abandoned.
    Methyl benzoate is used in perfume bases, such as ylang-ylang and tuberose types.
  • Chemical PropertiesMethyl benzoate is a colorless, oily, transparent, liquid. Pleasant odor.
  • Chemical Propertiescolourless to light yellow fragrant liquid
  • Chemical PropertiesMethyl paraben is methyl ester of p-hydroxybenzoic acid. It does not occur naturally and is produced commercially by esterification of p-hydroxybenzoic acid. Methyl benzoate has a fruity odor, also similar to cananga.
  • Chemical PropertiesMethyl benzoate has a fruity odor, similar to cananga.
  • OccurrenceMethyl benzoate can be isolated from the freshwater fern Salvinia molesta. It is one of many compounds that is attractive to males of various species of orchid bees, which apparently gather the chemical to synthesize pheromones; it is commonly used as bait to attract and collect these bees for study.
    Cocaine hydrochloride hydrolyzes in moist air to give methyl benzoate; drug - sniffing dogs are thus trained to detect the smell of methyl benzoate.

The oralLD50 values in mice and rats are 3330 and1350 mg/kg, respectively.
  • Fire HazardSpecial Hazards of Combustion Products: None
  • Safety ProfileModerately toxic by ingestion. Mildly toxic by skin contact. A skin and eye irritant. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical, water to blanket fire. When heated to decomposition it emits acrid smoke and irritating fumes.
  • Chemical SynthesisMethyl benzoate is formed by the condensation of methanol and benzoic acid, in presence of a strong acid such as hydrochloric acid . It reacts both at the ring and the ester. Illustrative of its ability to undergo electrophilic substitution, methyl benzoate undergoes acidcatalysed nitration with nitric acid to give methyl 3-nitrobenzoate. It also undergoes hydrolysis with addition of aqueous NaOH to give methanol and sodium benzoate, which can be acidified with aqueous HCl to form benzoic acid.
