2-Ethylfuran Usage And Synthesis
Chemical Propertiesclear colorless to yellow liquid
Chemical Properties2-Ethylfuran has a smoky burnt odor. When dilute, it has a warm, sweet odor. It has a coffee-like flavor (aroma).
OccurrenceReported 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.
Uses2-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.
PreparationBy dehydration of furyl methyl carbinol followed by reduction.
General Description2-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.
HazardFlammable liquid.
