29/9/2022· C 4 H 8 O 7, commonly known as 2-butanone, methyl acetone, ethyl methyl ketone, and MEK, is a ketone that contains both a methyl and an adjacent ethyl group. MEK is a white liquid that smells like acetone and has a musty odor. MEK is water insoluble, but soluble in alcohol, ether, and benzene. By its very nature, it is very flammable and volatile.

Methylethyl ketone oxime is the organic compound with the formula C2H5C (NOH)CH3. This colourless liquid is the oxime derivative of methyl ethyl ketone. Uses: MEKO, as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used. Prevents skinning in alkyd based systems.
A process for the recovery of methyl ethyl ketone (MEK) from an aqueous mixture of MEK and ethanol comprising extracting the MEK from the mixture using an extractive solvent selected from the group consisting of isopentane, the o-, m-, m-isomers of xylene, and

The main danger of acetone comes from its flammability. Its vapors have a flash point much below room temperature, so air/acetone mixtures can explode or burst into flames easily, even from static shocks. At temperatures above 486 °C, acetone will self-ignite. Storage Acetone is best stored in closed bottles, away from any source of heat. Disposal
