| Overview | Ethyl levulinate, as a potential green biomass-based platform compound, contains a carbonyl group and an ester group, has good reactivity, and can perform various chemical reactions such as hydrolysis, reduction, condensation, and nucleophilic addition. Taking advantage of the above reaction advantages, ethyl acetylpropionate is not only used in solvents, fragrances, oil additives and plasticizers, but also as an important pharmaceutical and chemical raw material. |
| content analysis | determined by non-polar column method in gas chromatography (GT-10-4). |
| toxicity | can be safely used in food (FDA, 172.515,2000). |
| usage limit | FEMA(mg/kg): soft drink 5.8; Cold drink 11; Candy, baked goods, 12. |
| use | GB 2760-96 specifies food spices that are allowed to be used. |
| Production method | It is formed by direct esterification of levulinic acid and ethanol in the presence of sulfuric acid in benzene or toluene. |
