3-Ethoxy-4-hydroxybenzaldehyde

에틸바닐린 C화학적 특성, 용도, 생산

화학적 성질

WHITE TO OFF-WHITE FINE CRYSTALLINE POWDER

화학적 성질

White or slightly yellowish crystals with a characteristic intense vanilla odor and flavor.

화학적 성질

Its odor resembles that of vanillin but is approximately three times as strong. Ethylvanillin can be prepared by method 2 as described for vanillin, using guethol instead of guaiacol as the starting material.

화학적 성질

Ethyl vanillin has an intense vanilla odor and sweet taste. The flavoring power is two to four times stronger than vanillin. Ethyl vanillin has been used in food since the 1930s; it enhances fruity and chocolate odor impression. Its addition is self-limiting, as too high a level may impart an unpleasant flavor in the product; the product is not stable. In contact with iron or alkali, it exhibits a red color and loses its flavoring power.

출처

Not reported found in nature; it can be distinguished from vanillin because of the yellow color developed in the presence of concentrated H2SO4.

용도

Ethyl Vanillin is a flavoring agent that is a synthetic vanilla flavor with approximately three and one-half times the flavoring power of vanillin. it has a solubility of 1 g in 100 ml of water at 50°c. it is used in ice cream, beverages, and baked goods.

용도

In flavoring and perfumery.

정의

ChEBI: A member of the class of benzaldehydes that is vanillin in which the methoxy group is replaced by an ethoxy group.

생산 방법

Unlike vanillin, ethyl vanillin does not occur naturally. It may be prepared synthetically by the same methods as vanillin, using guethol instead of guaiacol as a starting material; see Vanillin.

제조 방법

From safrole by isomerization to isosafrole and subsequent oxidation to piperonal; the methylene linkage is then broken by heating piperonal in an alcoholic solution of KOH; finally the resulting protocatechualdehyde is reacted with ethyl alcohol. From guaethol by condensation with chloral to yield 3-ethoxy-4-hydroxyphenyl trichloromethyl carbinol; this is then boiled with an alcoholic solution of KOH or NaOH, acidified, and extracted with chloroform to yield ethyl vanillin.

Aroma threshold values

Detection: 100 ppb; recognition: 2 ppm

Taste threshold values

Taste characteristics at 50 ppm: sweet, creamy, vanilla, smooth and caramellic.

Synthesis Reference(s)

The Journal of Organic Chemistry, 44, p. 3305, 1979 DOI: 10.1021/jo01333a006

일반 설명

Colorless crystals. More intense vanilla odor and taste than vanillin.

공기와 물의 반응

Slightly water soluble .

반응 프로필

Protect from light. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.

건강위험

ACUTE/CHRONIC HAZARDS: Toxic. May cause irritation on contact.

화재위험

Combustible

Pharmaceutical Applications

Ethyl vanillin is used as an alternative to vanillin, i.e. as a flavoring agent in foods, beverages, confectionery, and pharmaceuticals. It is also used in perfumery.
Ethyl vanillin possesses a flavor and odor approximately three times as intense as vanillin; hence the quantity of material necessary to produce an equivalent vanilla flavor may be reduced, causing less discoloration to a formulation and potential savings in material costs. However, exceeding certain concentration limits may impart an unpleasant, slightly bitter taste to a product due to the intensity of the ethyl vanillin flavor.

Safety Profile

Moderately toxic by ingestion, intraperitoneal, subcutaneous, and intravenous routes. A human skin irritant. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES and ETHERS.

Safety

Ethyl vanillin is generally regarded as an essentially nontoxic and nonirritant material. However, cross-sensitization with other structurally similar molecules may occur.
The WHO has allocated an acceptable daily intake for ethyl vanillin of up to 3 mg/kg body-weight.
LD50 (guinea pig, IP): 1.14 g/kg
LD50 (mouse, IP): 0.75 g/kg
LD50 (rabbit, oral): 3 g/kg
LD50 (rabbit, SC): 2.5 g/kg
LD50 (rat, oral): 1.59 g/kg
LD50 (rat, SC): 3.5–4.0 g/kg

저장

Store in a well-closed container, protected from light, in a cool, dry place. See Vanillin for further information.

비 호환성

Ethyl vanillin is unstable in contact with iron or steel, forming a redcolored, flavorless compound. In aqueous media with neomycin sulfate or succinylsulfathiazole, tablets of ethyl vanillin produced a yellow color. See Vanillin for other potential incompatibilities.

Regulatory Status

GRAS listed. Included in the FDA Inactive Ingredients Database (oral capsules, suspensions, and syrups). Included in nonparenteral medicines licensed in the UK.
