Butanone is an excellent organic solvent and important chemical raw material. It is an important solvent for coatings, inks, and diluents, with strong solubility and moderate volatilization rate. It is widely used in the formulation of paints, varnishes, resin coatings, and printing inks. Used for the production of adhesives, copper-clad laminates, and electronic resins, it is an important solvent for polyurethane slurries (PU slurries). As an important chemical intermediate, it is used to produce downstream products such as butanone oxime and methyl ethyl ketone peroxide. It is also used in various organic synthesis, as well as raw materials for the synthesis of fragrances and pharmaceuticals. Used as a lubricant dewaxing agent, it has important applications in petroleum refining processes. Used for solvents in semiconductor lithography and cleaning after integrated circuit lithography. Used as a reference substance for chromatographic analysis, organic solvent, and extractant; Used for the determination of analytical reagents such as cadmium, copper, and mercury.
