Sources and Potential Exposure. Methyl ethyl ketone has been detected in both indoor and outdoor air. Methyl ethyl ketone can be produced in outdoor air by the photooxidation of certain air pollutants, such as butane and other hydrocarbons. (1) Methyl ethyl ketone has been found in drinking water and surface water at a number of sites. (2)
2-Butanone, also known as methyl ethyl ketone (MEK), is a colorless liquid with a sweet, but sharp odor. 2-Butanone is manufactured in large amounts for use in paints, glues, and other finishes because it rapidly evaporates and will dissolve many substances.
21 lis 2022 · Health effects of acute exposure. MEK is an irritant by all routes of exposure and potentially toxic following inhalation, ingestion or dermal contact.
Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as crosslinking of unsaturated polyester resins. Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give diacetyl monoxime followed by conversion to the dioxime: [ 15 ]
How can methyl ethyl ketone affect my health? People exposed to MEK have nose, throat, skin, and eye irritation. If MEK is inhaled with other harmful chemicals, the damage can be more serious. Animals that breathed or swallowed high levels of MEK had serious health effects, including birth defects, fainting, and death.

You can be exposed to 2-butanone from food that naturally has a small amount of 2-butanone, or from contaminated drinking water. If you use paints, glues, coatings, or cleaning agents containing 2-butanone, you can be exposed from contaminated air or from skin contact with these products.
