Katrangan |
2,4-Heptadienal mundur utawa nyegah pangembangan "rasa tanpa rasa" ing lemak lan minyak otomatis oksidasi. Bisa disiyapake kanthi nyuda LiAlH4 saka asam dienoat sing disiapake dening sintesis Doebner, banjur dioksidasi karo Mn02 asil dienol menyang dienol sing cocog; kanthi metode Marshall lan Whiting. |
|
Properti Kimia |
2,4-Heptadienal duwe ambu, lemak ijo sing lemu lan oksidasi otomatis, iku nyebabake utawa nyegah pangembangan "rasa sing ora disenengi". |
