説明

Methyl 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.

化学的特性

Methyl 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.

化学的特性

Methyl benzoate has a fruity odor, similar to cananga.

化学的特性

colourless to light yellow fragrant liquid

化学的特性

Methyl benzoate is a colorless, oily, transparent, liquid. Pleasant odor.

化学的特性

Methyl 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.

天然物の起源

Methyl 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.

使用

Methyl benzoate is used in perfumes..

使用

In perfumes (Peau d'Espagne).

定義

ChEBI: A benzoate ester obtained by condensation of benzoic acid and methanol.

製造方法

By heating benzoic acid and dimethyl sulfate to high temperature, or by exchange between ethyl benzoate and methanol in KOH solution.

Aroma threshold values

Detection: 110 ppb

Taste threshold values

Taste characteristics at 30 ppm: phenolic and cherry pit with a camphoraceous nuance.

一般的な説明

A crystalline solid or a solid dissolved in a liquid. Denser than water. Contact may slightly irritate skin, eyes and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals.

空気と水の反応

Slightly soluble in water. Hydrolyzes slowly in contact with water .

反応プロフィール

Methyl benzoate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Methyl benzoate reacts with strong oxidizing agents and strong bases and hydrolyzes slowly in contact with water. .

危険性

Toxic by ingestion.

健康ハザード

Methyl benzoate is a mild skin irritant. Theacute oral toxicity in test animals was oflow order. The toxic symptoms in animalsfrom oral administration of this compoundwere tremor, excitement, and somnolence.The LD50 value varies with species. The oralLD50 values in mice and rats are 3330 and1350 mg/kg, respectively.

健康ハザード

Irritating to the eyes, nose, throat, upper respiratory tract, and skin. May cause allegic skin and respiratory reactions.

火災危険

Special Hazards of Combustion Products: None

安全性プロファイル

Moderately 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 Synthesis

Methyl 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.

職業ばく露

Used as food additive and as a solvent for cellulose esters and ethers, resins and rubber.

純化方法

Wash the ester with dilute aqueous NaHCO3, then water, dry with Na2SO4 and fractionally distil it in a vacuum. [Beilstein 9 IV 283.]

廃棄物の処理

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
