2-Nitropropane（Dimethylnitromethane）

Chemical natures

2-Nitropropane also known as dimethylnitromethane or isonitropropane is a colourless, oily liquid with a mild and sweet odour. It is flammable and soluble in water. It is also soluble in many organic solvents including chloroform. Its vapours may form an explosive mixture with air. It is used as a cosolvent in paints to improve pigment wetting, flow properties, and electrostatic processing; it also reduces the paint drying time.

Applications

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.
