Description and Uses
2-Nitropropane, also known as dimethylnitromethane or isonitropropane, is a colourless, oily liquid with a mild and sweet odour. This flammable compound is soluble in water and various organic solvents, including chloroform. Its vapors can form an explosive mixture when combined with air. 2-Nitropropane serves as a co-solvent in paint formulations, enhancing pigment wetting, optimizing flow properties, and facilitating electrostatic processing. Additionally, it contributes to a shorter paint drying time.
2-Nitropropane is primarily used as a solvent for organic compounds and coatings; with vinyl resins, epoxy paints, nitrocellulose, and chlorinated rubber; in printing inks, adhesives, and printing as flexographic inks; maintenance with traffic markings on roads and highways; shipbuilding; and general maintenance. It also has limited use as a paint and varnish remover. 2-Nitropropane is also used as a solvent in food processing industries for fractionation of a partially saturated vegetable oil.
