Description

Methyl Ethyl Ketone, also known as 2-Butanone, is a member of the Ketone family and considered as aprotic/protophilic solvent. It is a colorless and flammable liquid with a minty or acetone-like odor and possesses high solubility in water. Lab grade chemicals possess reasonable purity but do not comply with any official standards for quality or purity. The Methyl Ethyl Ketone, Lab Grade at Lab Alley possesses sufficient purity with low concentration of heavy metals and other impurities. Laboratory grade is also known as the Chemically Pure (CP) and the Laboratory Reagent (LR). Lab grade chemicals are widely used in educational labs and are ideal for everyday laboratory use.

Information On Methyl Ethyl Ketone From Wikipedia

Butanone, also known as methyl ethyl ketone (MEK), is an organic compound with the formula CH3C(O)CH2CH3. This colorless liquid ketone has a sharp, sweet odor reminiscent of butterscotch and acetone. It is produced industrially on a large scale, and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent.

As A Solvent
Butanone is an effective and common solvent and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues, and as a cleaning agent. It has similar solvent properties to acetone but boils at a higher temperature and has a significantly slower evaporation rate.[12] Unlike acetone, it forms an azeotrope with water, making it useful for azeotropic distillation of moisture in certain applications. Butanone is also used in dry erase markers as the solvent of the erasable dye.

As A Plastic Welding Agent
As butanone dissolves polystyrene and many other plastics, it is sold as "model cement" for use in connecting parts of scale model kits. Though often considered an adhesive, it is actually functioning as a welding agent in this context.

Other Uses
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.
