• 外観

  無色～ほとんど無色透明液体

• 用途

  製造用剤

• 説明

  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.

• 化学的特性

  2-Nitropropane, also known as 2-NP, is an aliphatic nitro compound that appears as a colourless, flammable liquid with a mild fruity odour. It can dissolve in water (1.7 mL/100 mL at 20C) and is miscible with organic solvents.
  Like other nitroalkanes, 2-nitropropane exists in equilibrium with 2-propane nitronic acid (HSDB 1988). A 0.01 M aqueous solution of 2-NP has a pH of 6.2. When reacted with inorganic bases and amines, 2-nitropropane forms salts that are flammable when dry. It is sensitive to detonation when combined with oxidizers, and a mixture of 2-nitropropane and ammonium nitrate serves as a commercial explosive.

• 物理的性質

  Colorless, oily liquid with a mild, fruity odor. 2-Nitropropane was detected in two studies at concentrations of 3.1 and 5.2 ppm_v (Crawford et al., 1984).

• 使用

  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.

• 製造方法

  The synthesis of 2-nitropropane can be accomplished directly by nitration of 2-halopropanes with sodium nitrite. With 2-iodopropane, the reaction is carried out in dry DMF in the presence of urea. For the slower reacting 2-bromopropane, a longer reaction time and the presence of phloroglucinol as a nitrite ester scavenger is required.
  Like 1-nitropropane, 2-nitropropane is also produced by vapor-phase nitration of propane with nitric acid at elevated temperature and pressure (Baker and Bollmeier 1978).

• 定義

  ChEBI: 2-nitropropane is a secondary nitroalkane that is propane in which a hydrogen at position 2 has been replaced by a nitro group. Mainly used as a solvent (b.p. 120℃). It has a role as a hepatotoxic agent, a carcinogenic agent, a polar aprotic solvent and a xenobiotic.

• 一般的な説明

  2-Nitropropane is a clear, colorless liquid with a pleasant odor that is soluble in many organic solvents, including chloroform. Its vapors may form an explosive mixture with air.

• 空気と水の反応

  Highly flammable.

• 反応プロフィール

  2-Nitropropane is sensitive to heat. Can react with amines/heavy metal oxides, strong acids, strong alkalis, and chlorosulfonic acid. . The heat of adsorption of 2-Nitropropane on carbon, such as that found in cartridge respirators, is extremely high. Metal oxide catalysts, such as copper oxide or manganese oxide, can initiate ignition, therefore carbon respirators should not be used in environments that have a high vapor concentration of 2-Nitropropane.

• 健康ハザード

  2-Nitropropane is a lung irritant. The acute effects of exposure to 2-nitropropane at 20-45 p.p.m. on workmen were anorexia, nausea, vomiting, diarrhea and severe occipital headache. Liver effects have been observed in animals chronically exposed to 2-nitropropane by inhalation.

• 発がん性

  2-Nitropropane was classified by the International Agency for Research on Cancer (IARC) as Group 2B, possibly carcinogenic to humans, based on animal studies linking exposure to liver cancer in rats.The carcinogenicity of 2-nitropropane in humans was not evaluated due to the lack of adequate epidemiological data.

• 環境運命予測

  Photolytic. Anticipated products from the reaction of 2-nitropropane with ozone or OH radicals in the atmosphere are formaldehyde and acetaldehyde (Cupitt, 1980).

• 輸送方法

  UN2608 Nitropropanes, Hazard Class: 3; Labels: 3-Flammable liquid.

• 純化方法

  Purify it as for nitromethane. [Beilstein 1 IV 230.]

• 不和合性

  1-Nitropropane, a nitroparaffin compound, forms explosive mixture with air. Contact with heavy metal oxides may cause decomposition. Mixtures with hydrocarbons are extremely flammable. Attacks some plastics, rubber and coatings. May explode on heating. Violent reaction with strong bases; strong acids and metal oxides. Shock-sensitive compounds are formed with acids, amines, inorganic bases and heavy metal oxides. Incompatible with strong oxidizers, combustible materials. 2-Nitropropane reacts with activated carbon causing decomposition. This reaction may occur in activated carbon respirator filters.

• 廃棄物の処理

  Incineration: large quantities of material may require nitrogen oxide removal by catalytic or scrubbing processes. Dilute with pure kerosene and burn with care as it is potentially explosive. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
