Butanoni

Butanoni, also known as methyl ethyl ketone (MEK), is an organic compound with the chemical formula CH3COCH2CH3. It is a colorless liquid with a sharp, sweet odor similar to acetone. Butanoni is a ketone and is structurally similar to acetone, differing by the presence of an ethyl group instead of a methyl group on one side of the carbonyl. It is miscible with most organic solvents and has limited solubility in water.

Industrially, butanoni is produced through the dehydrogenation of 2-butanol. It is widely used as a solvent in various applications. Its ability to dissolve resins, coatings, and adhesives makes it a common component in paints, lacquers, varnishes, and printing inks. It is also used in the production of rubber cements and as a degreasing agent. In laboratories, it serves as a solvent for chemical reactions and as a reagent in organic synthesis.

Butanoni is considered a volatile organic compound (VOC) and its vapors can be flammable. Exposure to high concentrations can cause irritation to the eyes, skin, and respiratory system. Prolonged or repeated exposure may lead to more serious health effects. Due to its flammability and potential health hazards, butanoni should be handled with appropriate safety precautions, including adequate ventilation and personal protective equipment.
