Kjemiske egenskaper |
HVIT TIL AVHVITEFIN KRYSTALLINEPULVER |
Kjemiske egenskaper |
White or slightly yellowish crystals with a characteristic intense vanilla odor and flavor. |
Kjemiske egenskaper |
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. |
Kjemiske egenskaper |
Etyl vanillin har en intens vaniljelukt og søt smak. Smaksstyrken er to til fire ganger sterkere enn vanil [1] lin. Etylvanillin har blitt brukt i mat siden 1930-tallet; det forbedrer fruktig og sjokolade luktinntrykk. Tilsetningen er selvbegrensende, ettersom for høyt nivå kan gi en ubehagelig smak i produktet; produktet er ikke stabilt. I kontakt med jern eller alkali, har den en rød farge og mister smaksstyrken. |
Bruker |
Ethyl Vanillin er et smaksmiddel som er en syntetisk vaniljesmak med omtrent tre og halv ganger smaksstyrken til vanillin. den har en løselighet på 1 g i 100 ml vann ved 50 ° C. den brukes i iskrem, drikkevarer og bakevarer. |
Bruker |
In flavoring and perfumery. |
Definition |
ChEBI: A member of the class of benzaldehydes that is vanillin in which the methoxy group is replaced by an ethoxy group. |
Produksjonsmetoder |
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. |
Preparation |
Fra safrol byisomerisering til isosafrol og påfølgende oksidasjon til piperonal; temetylenbindingen brytes deretter ved oppvarming av piperonal i en alkoholoppløsning av KOH; til slutt reagerer det resulterende protokatechualdehydet med etylalkohol. Fra guaetol ved kondensering med klor for å gi 3-etoksy-4-hydroksyfenyltriklormetylkarbinol; dette blir deretter kokt med en alkohol [1] holisk løsning av KOHor NaOH, surgjort og ekstrahert med kloroform for å gi etylvanillin. |
Aroma threshold values |

Taste threshold values |
Taste characteristics at 50 ppm: sweet, creamy, vanilla, smooth and caramellic. |
Generell beskrivelse |
Fargeløse krystaller. Mer intens vaniljelukt og smak enn vanillin. |
Luft- og vannreaksjoner |
Slightly water soluble . |
Reactivity Profile |
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. |
Health Hazard |
ACUTE/CHRONIC HAZARDS: Toxic. May cause irritation on contact. |
Fire Hazard |
Brennbar |
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. |
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. |
Sikkerhet |
Ethyl vanillin is
generally regarded as an essentially nontoxic and nonirritant material.
However, cross-sensitization with other structurally similar molecules may
occur. |
storage |
Oppbevares i godt lukket beholder, beskyttet mot lys, på et kjølig, tørt sted. Se Vanillin for mer informasjon. |
Uforlikeligheter |
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. |
