Ethyl-4-hydroxy-2-methyl-3(2H)-furanone yog cov kua tsis muaj xim uas muaj txiv hmab txiv ntoo, tsw qab. Nws yog siv nyob rau hauv kev tsim cov flavors thiab fragrances.
5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone tuaj yeem tau los ntawm cov tshuaj tiv thaiv ntawm butanedione nrog dilute sulfuric acid, ua raws li kev kho mob nrog ib qho absorber uas muaj propylene glycol. thiab 4-ethyl-2methoxyphenol.
Cov khoom yog ces kho nrog hluav taws xob hluav taws xob los tsim furfural, uas reacts nrog anthranilate los ua methyl anthranilate. Methyl anthranilate tuaj yeem hloov mus rau phenylmethyl los ntawm kev ua haujlwm nrog glycosidase.
