Monomethylaniline

N-메틸아닐린 C화학적 특성, 용도, 생산

화학적 성질

N-Methylaniline is a yellow to light brown oily liquid with a weak, ammonia-like odor. Turns reddishbrown if left standing. The odor threshold is 1.7 ppm

물리적 성질

Colorless to yellow to pale brown liquid with a faint, ammonia-like odor. Odor threshold concentration is 1.7 ppm (quoted, Amoore and Hautala, 1983).

용도

N-Methylaniline is used as a solvent and in organic synthesis.

용도

Chemical syntheses

용도

Organic synthesis, solvent, acid acceptor.

정의

ChEBI: A methylaniline that is aniline carrying a methyl substituent at the nitrogen atom.

Synthesis Reference(s)

위험도

Toxic by ingestion, inhalation, and skin absorption. Methemoglobinemia and central nervous system impairment.

건강위험

Recommended Personal Protective Equipment: Approved respirator; rubber gloves; splash proof goggles; Symptoms Following Exposure: Inhalation causes dizziness and headache. Ingestion causes bluish discoloration (cyanosis) of lips, ear lobes, and fingernail beds. Liquid irritates eyes. Absorption through skin produces same symptoms as for ingestion; General Treatment for Exposure: INHALATION: remove victim to fresh air and call a physician at once; administer oxygen until physician arrives. INGESTION: give large amount of water; get medical attention at once. EYES or SKIN: flush with plenty of water for at least 15 min.; if cyanosis is present, shower with soap and warm water, with special attention to scalp and finger nails; remove any contaminated clothing; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Term Inhalation Limits: Data not available; Toxicity by Ingestion: Data not available; Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant Characteristics: Data not available; Odor Threshold: Data not available.

화학 반응

Reactivity with Water No reaction; Reactivity with Common Materials: May attack some forms of plastic; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Poison by ingestion and intravenous routes. Moderately toxic by subcutaneous route. When heated to decomposition it emits toxic fumes of NOx.

잠재적 노출

The material is used as an intermediate in organic synthesis, as a solvent and as an acid acceptor

Carcinogenicity

N-methyl aniline (1.95 g/kg of food) given together with sodium nitrite (1.0 g/l of drinking water) to Swiss mice resulted in a 17% incidence of lung adenomas and a 14% incidence of malignant lymphomas; there were no carcinogenic effects in animals treated with Nmethyl aniline alone, suggesting that in vivo nitrosation is necessary for forming carcinogenic nitrosamines.
In bacterial mutagenicity assays N-methyl aniline was negative with or without metabolic activation.

환경귀착

Soil. Reacts slowly with humic acids or humates forming quinoidal structures (Parris, 1980).

운송 방법

UN2294 N-Methylaniline, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Dry it with KOH pellets and fractionally distil it under vacuum. Acetylate, and the acetyl derivative is recrystallised to constant melting point (m 101-102o), then hydrolysed with aqueous HCl and distilled from zinc dust under reduced pressure. [Hammond & Parks J Am Chem Soc 77 340 1955, Beilstein 12 IV 241.]

폐기물 처리

Controlled incineration whereby oxides of nitrogen are removed from the effluent gas by scrubber, catalytic or thermal device.
