| | Ethyl levulinate Usage And Synthesis |
| Chemical Properties | clear yellowish liquid | | Chemical Properties | Ethyl levulinate has an ethereal, fruity, green, sweet, pineapple, apple, rhubarb odor. | | Occurrence | Reported found in white bread, roasted onion, wheat bread, cognac, malt whiskey, grape wines, cocoa, bilberry
wine, Bourbon vanilla and cherimoya (Annona cheremolia Mill.). | | Uses | Ethyl levulinate was used to develop a preparative HPLC method to preserve wine aromas and isolates fruity characteristics of red wine aroma extracts. | | Uses | Ethyl levulinate is used to develop a preparative HPLC method to preserve wine aromas and isolates fruity characteristics of red wine aroma extracts | | Uses | Solvent for cellulose acetate and starch ethers,
flavoring. | | Definition | ChEBI: Ethyl levulinate is an oxo carboxylic acid. | | Preparation | Usually obtained by direct esterification of levulinic acid with ethanol and H2SO4 in benzene or in toluene; also in the
presence of HCI in ethanol; other methods starting from glucose, fructose and others are of less importance. | | Taste threshold values | Taste characteristics at 40 ppm: fruity, green, waxy and melon. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 59, p. 486, 1994 DOI: 10.1021/jo00081a034
