Beschreibung
2-Ethylfuran is an empirical isomer of one of the Furanderivatives isolated from the volatile aroma of Coffee (roasted), namely 2,5-dimethylfuran. This Furan is used in imitation Coffee flavour and also occasionally in Caramel flavour. It requires considerable fixation for the latter purpose, due to the volatility of this material, while in Coffee flavor, the most volatile portion is generally the most important portion of the flavor picture. 2-Ethylfuran is produced from Furyl methyl carbinol by dehydration, followed by reduction. The carbinol is obtained by Grignard reaction on Furfural. 2-Ethylfuran is approved by the American F.D.A. as a synthetic flavor or adjuvant.
Chemische Eigenschaften
2-Ethylfuran has a smoky burnt odor. When dilute, it has a warm, sweet odor. It has a coffee-like flavor (aroma).
Chemische Eigenschaften
clear colorless to yellow liquid
Occurrence
Reported found in tomato, coffee, peppermint and spearmint oil, Parmesan cheese, bell pepper, cooked egg, smoked fish, roasted chicken, cooked beef, cocoa, coffee, tea, pecans, filberts and soybeans.
Verwenden
2-Ethylfuran was used to investigate the gas phase products formed from the Cl atoms initiated reactions of 2-ethylfuran by in situ long-path FTIR absorption spectroscopy. It was also used in the synthesis of 4-oxo-(E)-2-hexenal via ring opening reaction using aqueous N-bromosuccinimide.
Definition
ChEBI: 2-ethylfuran is a member of the class of furans that is furan in which the hydrogen atom at position 2 has been replaced by an ethyl group. It has a role as a plant metabolite, a fragrance, a Maillard reaction product and a bacterial metabolite. It is a member of furans and a volatile organic compound. It is functionally related to a furan.
synthetische
By dehydration of furyl methyl carbinol followed by reduction.
Allgemeine Beschreibung
2-Ethylfuran undergoes tetraphenylporphin-photosensitized oxygenation in non-polar aprotic solvents via (4+2)-cycloaddition of singlet oxygen to yield the corresponding monomeric unsaturated secondary ozonide.
Hazard
Flammable liquid.
