  Chemical Properties Methyl ethyl ketone is an organic compound with the chemical formula CH3COCH2CH3 and a molecular weight of 72.11. It is a colorless and transparent liquid with an odor similar to acetone. Easily volatile. It is miscible with ethanol, ether, benzene, chloroform and oil. Soluble in 4 parts of water, but the solubility decreases when the temperature increases, and can form azeotropic mixture with water. Low toxicity, LD50 (rat, oral) 3300mg/kg. flammable, vapor can form explosive mixture with air. High concentration of vapor has anesthetic properties.   Application: Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) is an organic solvent of relatively low toxicity, which is found in many applications. It is used in industrial and commercial products as a solvent for adhesives, paints, and cleaning agents and as a de-waxing solvent. A natural component of some foods, methyl ethyl ketone can be released into the environment by volcanoes and forest fires.It is used in themanufacture of smokeless powder and colorless synthetic resins, as a solvent, and insurface coating. It is also used as a flavoringsubstance in food. MEK is used as a solvent for various coating systems, for example, vinyl, adhesives, nitrocellulose, and acrylic coatings. It is used in paint removers, lacquers, varnishes, spray paints, sealers, glues, magnetic tapes, printing inks, resins, rosins, cleaning solutions, and for polymerization. It is found in other consumer products, for example, household and hobby cements, and wood-filling products. MEK is used in dewaxing lubricating oils, the degreasing of metals, in the production of synthetic leathers, transparent paper and aluminum foil, and as a chemical intermediate and catalyst. It is an extraction solvent in the processing of foodstuffs and food ingredients. MEK can also be used to sterilize surgical and dental equipment. In addition to its manufacture, environmental sources of MEK include exhaust from jet and internal combustion engines, and industrial activities such as gasification of coal. It is found in substantial amounts in tobacco smoke. MEK is produced biologically and has been identified as a product of microbial metabolism. It has also been found in plants, insect pheromones, and animal tissues, and MEK is probably a minor product of normal mammalian metabolism. It is stable under ordinary conditions but can form peroxides on prolonged storage; these may be explosive. Methyl ethyl ketone
