Description

Methyl ethyl ketone is used as a solvent for lacquers, adhesives, cleaning materials to be electroplated, degreasing, rubber and rubber cement, printing inks, and paints, wood stains and varnishes, paint removers, in cleaning solutions, as a catalyst, and as a carrier. Substance Details : Substance name: Methyl ethyl ketone CASR number: 78-93-3 Molecular formula: C4H8O Synonyms: 2-Butanone; MEK; Ethyl methyl ketone; Butanone; methyl acetone; butan-2-one Physical Properties : Methyl ethyl ketone is a colourless liquid with a faint sweet odour. Melting Point: -86.3°C Boiling Point: 79.6°C Vapour Density: 2.5 Specific Gravity: 0.805 Flashpoint: -6°C Chemical Properties : Methyl ethyl ketone is a flammable liquid. It is partially soluble in water, and soluble in most other organic solvents. It will float on water while it rapidly dissolves in it. Uses : MEK is a liquid solvent used in surface coatings, adhesives, printing inks, chemical intermediates, magnetic tapes and lube oil dewaxing agents. MEK also is used as an extraction medium for fats, oils, waxes and resins. It is a highly efficient and versatile solvent for surface coatings. Because of its effectiveness as a solvent, MEK is especially valuable in formulating high solids coatings, which help to reduce emissions from coating operations. MEK is a natural component of many foods, including apple juice, beans, chicken, honey and a variety of cheeses. Synonyms for MEK are 2-butanone, ethyl methyl ketone, and methyl acetone.
