acetone and mek
MEK (methyl ethyl ketone) and acetone (ace) are not the same substance; they are two distinct organic compounds.
MEK (methyl ethyl ketone): Chemically known as methyl ethyl ketone, also called butanone or methyl ethyl ketone, with the molecular formula C₄H₈O and structural formula CH₃COCH₂CH₃. It is a medium-boiling-point ketone solvent with a boiling point of approximately 79.6°C and a flash point of -9°C.
MEK exhibits excellent solubility and is commonly used in lubricant dewaxing, coatings, resins, pharmaceuticals, and electronic industry cleaning applications.
Acetone (Ace): Chemically known as acetone, also called dimethyl ketone or methyl ethyl ketone, with the molecular formula C₃H₆O and structural formula CH₃COCH₃. It is a low-boiling-point ketone solvent with a boiling point around 56°C and a flash point of -20°C.
Acetone exhibits higher volatility and is extensively used in explosives, plastics, rubber, leather processing, and other industries. It also serves as a key raw material for synthesizing other chemicals.
