Butanone is mainly used as a solvent, such as azeotropic distillation for the dewaxing of lubricating oil, coating industry and various resin solvents, vegetable oil extraction process and refining process. Its advantages are strong solubility, lower volatility than acetone, and Medium-boiling ketone solvents. Butanone is also an intermediate for the preparation of medicines, dyes, detergents, perfumes, antioxidants, and certain catalysts. Synthetic anti-peeling agent methyl ethyl ketone oxime, polymerization catalyst methyl ethyl ketone peroxide, corrosion inhibitor A Alkynyl alcohol, etc., is used as an imaging agent for lithography of integrated circuits in the electronics industry.
