3-Methylbutyl 3-methylbutanoate Chemical Properties,Usage,Production
Aroma
Peculiar fruity odor reminiscent of ripe
apples, or more like the overwhelmingly
choking odor of apples stored in a warehouse,
almost a "fermented" apple odor.
Fresh-fruity taste, reminiscent of apple rind.
Also of raspberry.
Finds extensive use of 3-Methylbutyl 3-methylbutanoate in flavor compositions,
primarily in imitation Apple, and in the related "wine" or "Champagne" type imitation
flavors for soft candy, beverages, etc. Further
as a modifier in imitation Apricot, Banana,
Cherry, Honey, Peach, Pineapple, Mango,
Raspberry, Strawberry, Walnut - and in combination flavors such as Cream Soda, Tutti.
frutti, Rum and in Vanilla.
A specific use is the application in imitation
Gooseberry flavor. Concentrations are usually
around 50-60 ppm, except in chewing gum,
where it may be as high as 400 ppm. (Calculated on functional consumer product).
Description
Isoamyl isovalerate has a characteristic fruity odor and a sweet apple-like flavor. May be prepared by passing vapors of isoamyl alcohol and isovaleric aldehyde over a copper uranium based catalyst at 240 - 280°C in the presence of hydrogen.
Chemical Properties
Isoamyl isovalerate has a fruity, sweet, apple, apricot, mango-characteristic fruity odor and sweet-apple-like flavor.
Occurrence
Reported found in the ether oil from leaves of Eucalyptus microcorys, angelica root oil and mastic gum leaf and fruit oils. Also reported in wine, oil of hop, olive oil, banana, tomato, peppermint and spearmint oil, beer, rum, whiskies, cider, sherry, plum, quince, cherimoya and lamb’s lettuce.
Uses
Isopentyl 3-Methylbutanoate is used in method for preparing essence compound of olfactory recognition book suitable for olfactory sense of Chines.
Uses
As apple essence for flavoring liqueurs and candy.
Production Methods
3-Methylbutyl 3-methylbutanoate can be produced by:
1) direct esterification of iso-Amyl alcohol
with iso-Valerie acid under azeotropic conditions.
2) controlled oxidation of iso-Amyl alcohol with Potassium bichromate-Sulfuric
acid mixture.
Preparation
By passing vapors of isoamyl alcohol and isovaleric aldehyde over a copper–uranium-based catalyst at 240 to 280°C in the presence of hydrogen
Definition
ChEBI: Isoamyl isovalerate is a fatty acid ester.
