MSDS Information

• 3-Nitrophenylamine

3-ニトロアニリン 化学特性,用途語,生産方法

• 外観

  黄色～黄褐色, 結晶性粉末

• 溶解性

  アルコール, エーテルに可溶。水に微溶 (0.005g/100ml水, 25℃)。

• 用途

  染料中間体 (NITE CHRIP)

• 化学的特性

  3-Nitroaniline is a ochre-yellow to orange crystalline powder, crystallizes as yellow needles from water. It is moderately soluble in organic solvents and sparingly soluble in water (0.11 %).

• 物理的性質

  Yellow, rhombic crystals or powder. Finely dispersered particles form explosive mixtures. Combustible.

• 使用

  Dyestuff intermediate. Acetylation of 3-nitroaniline followed by reduction gives 3-aminoacetanilide. Diazotization, followed by reduction of the diazosulfonate with ammonium bisulfite and subsequent hydrolysis, gives (3-nitrophenyl) hydrazine; an intermediate in the production of pyrazolone azo coupling components. 3-Nitroaniline is used as a diazo component (Fast Orange R Base) in azo dyes (e.g., C.I. Disperse Yellow 5 and C.I. Acid Orange 18).

• 調製方法

  1,3-Dinitrobenzene is added to warm water containing magnesium sulfate. An aqueous solution of sodium hydrogen sulfide (6 molar equivalents) is added gradually to the vigorously stirred emulsion, and reduction is completed by heating to 90 ℃. The 3-nitroaniline produced solidifies on cooling and is separated by filtration.

• 製造方法

  M-nitroaniline partial reduction.

• 一般的な説明

  Yellow needles or yellow powder.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  Thermal stability of 3-Nitroaniline is reduced by various impurities. 3-Nitroaniline may be sensitive to prolonged exposure to light. 3-Nitroaniline may react explosively with ethylene oxide at 266° F. 3-Nitroaniline is incompatible with acids (nitric, sulfuric), acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. . Unstable when heated.

• 危険性

  Moderate fire risk. Toxic when absorbed by skin.

• 火災危険

  Flash point data for 3-Nitroaniline are not available; however, 3-Nitroaniline is probably combustible.

• 環境運命予測

  Biological. A bacterial culture isolated from the Oconee River in North Georgia degraded 3- nitroaniline to the intermediate 4-nitrocatechol (Paris and Wolfe, 1987). A Pseudomonas sp. strain P6, isolated from a Matapeake silt loam, did not grow on 3-nitroaniline as the sole source of carbon. However, in the presence of 4-nitroaniline, all of the applied 3-nitroaniline metabolized completely to carbon dioxide (Zeyer and Kearney, 1983). In the presence of suspended natural populations from unpolluted aquatic systems, the second-order microbial transformation rate constant determined in the laboratory was reported to be 4.6 ± 0.1 x 10^-13 L/organismh (Steen, 1991).
  In activated sludge inoculum, following a 20-d adaptation period, no degradation was observed (Pitter, 1976).
  Chemical/Physical. Reacts with acids forming water soluble salts.

• 純化方法

  Purify it as for o-nitroaniline. Warning: it is absorbed through the skin. [Beilstein 12 IV 1589.]
