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
