| Hazard Information | Back Directory | [Chemical Properties]
Clear colorless to yellow liquid | [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. | [Occurrence]
Reported found in cooked chicken, beef and pork | [Uses]
4-HEXEN-3-ONE is used as gB 2760--1996 specifies the permitted use of food flavorings. | [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ChEBI: 4-hexen-3-one is an enone that is hex-2-ene in which the two methylene hydrogens at position 4 have been replaced by an oxo group.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. | [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.
