| | 4-HEXEN-3-ONE Usage And Synthesis |
| Description | May be synthesized by hydration of 4-hexen-2-yne aqueous
H2S04/HgS04; by hydrogenation of 2-hexen-5-yn-4-one over PdCaC03 catalyst in methanol. | | Chemical Properties | 4-Hexene-3-one has a pungent, acrid, metallic, ethereal odor
| | Chemical Properties | Clear colorless to yellow liquid | | Occurrence | Reported found in cooked chicken, beef and pork | | Preparation | By hydration of 4-hexen-2-yne aqueous H2SO4-HgSO4; by hydrogenation of 2-hexen-5-yn-4-one over Pd-CaCO3 catalyst
in methanol.
| | Definition | ChEBI: 4-hexen-3-one is an enone that is hex-2-ene in which the two methylene hydrogens at position 4 have been replaced by an oxo group. It has a role as a flavouring agent, a plant metabolite and a human metabolite. | | Aroma threshold values | Aroma characteristics at 1.0%: pungent, horseradish and mustard with an ethyl vinyl ketone ethereal note,
notes reminiscent of vinegar and rum. | | Taste threshold values | Taste characteristics at 10 ppm: pungent mustard, pepper, horseradish, rum, roasted onion and slightly tropical nuances | | General Description | 4-Hexen-3-one is an unsaturated aldehyde that is reported to occur in strawberry fruit, essential oil of Ruta graveolens and Holigarna grahamii leaves. Due to its fruity fragrance, it is also used in the perfume industry. |
