3,4-Hexanedione Usage And Synthesis
- Description3,4-Hexanedione has a pungent, unpleasant odor reminiscent of butter and a taste similar to that of diacetyl. May be prepared synthetically by condensation of ethyl propionate in the presence of sodium metal, followed by oxidation of the resulting propionin with copper acetate or ferric chloride.
- Chemical Properties3,4-Hexanedione has an aromatic, toasty, burnt, buttery, nutty, caramel-eggy, pungent odor.
- Chemical Propertiesclear yellow liquid
- OccurrenceReported found in cauliflower, coffee
- PreparationBy condensation of ethyl propionate in the presence of sodium metal, followed by oxidation of the resulting propionin with copper acetate or ferric chloride.
- Aroma threshold valuesAroma characteristics at 1.0%: sweet buttery, creamy, slightly cooked caramel and burnt sugary reminiscent of ghee and eggy vanillas.
