Ethyl vinyl ketone Usage And Synthesis

Chemical Properties	clear colorless to amber liquid
Chemical Properties	1-Penten-3-one has a powerful, penetrating odor. This compound is also reported as having a pungent, mustard odor. It polymerizes readily with heat or in the presence of alkali.
Occurrence	Reported found in banana, orange peel oil, grapefruit juice and peel, peach, lean fish, fish oil, chicken fat, black tea, soybean, defatted soybean, lovage leaf, endive, chive, oysters, clam, boiled and cooked beef, kiwifruit, guava, grapes, tomato, butter and maté.
Uses	Ethyl vinyl ketone is used as reagent for annulation.
Preparation	By reacting ethylene with a mixture of propionyl chloride, aluminum trichloride and carbon disulfide.
Definition	ChEBI: 1-penten-3-one is an enone that is pent-1-ene substituted by an oxo group at position 3. It has a role as a human metabolite, a flavouring agent, a plant metabolite and a genotoxin.
Aroma threshold values	Detection: 1 to 13 ppb
Taste threshold values	Taste characteristics at 5.0 ppm: pungent, ethereal, peppery, garlic, onion, fishy and mustard with a hot nuance.
General Description	Ethyl vinyl ketone is a volatile flavor compound mainly found in tomatoes. It may be responsible for the raw bean odor and flavor in soybeans.
Safety Profile	Poison by intravenous route. When heated to decomposition it emits acrid smoke and irritating fumes. See also KETONES
