2-Methylbutylacetat ist ein Carbonsäureester, der sich von der Essigsäure und von 2-Methylbutan-1-ol ableitet.
Vorkommen
2-Methylbutylacetat kommt in verschiedenen Früchten vor, darunter in Äpfeln (z. B. Sorten Fuji, Gala und Granny Smith),[3][4][5][6][7][8] Birnen,[9] Melonen,[10][11] Bananen,[12] Erdbeeren,[13] Feigen,[14] Jackfrucht[15] und den Früchten von Strychnos cocculoides (Gattung Brechnüsse).[16] Es kommt auch in Olivenöl[17] und Cognac[18] vor.
Gewinnung und Darstellung
2-Methylbutylacetat kann durch Reaktion von Essigsäure mit 2-Methylbutanol gewonnen werden.[19]
Verwendung
2-Methylbutylacetat ist in der EU unter der FL-Nummer 09.286 als Aromastoff für Lebensmittel allgemein zugelassen.[20]
