모노나이트로톨루엔 C화학적 특성, 용도, 생산
화학적 성질
Nitrotoluene is formed in 3 isomeric forms.
The o-and m-forms are yellow liquids or solids. The p-form
is a pale yellow crystalline solid. All have weak aromatic
odors. The Odor Thresholds are: 0.05 mg/L (o-isomer);
1.74 ppm (m-isomer).
일반 설명
Exists as either a yellow solid crystal or liquid. Melting point 32 to 59°F. Insoluble in water and soluble in alcohol. Denser than water. Toxic by ingestion, inhalation or skin contact. Flash point 223°F. Boiling point 428°F. Produces toxic oxides of nitrogen during combustion.
공기와 물의 반응
Insoluble in water.
반응 프로필
p-NITROTOLUENE and sulfuric acid explode at 80°C [Chem. Eng. News 27:2504]. Many explosions have occurred in the distillation of nitrotoluene owing to its heat sensitivity. May become unstable in the presence of strong bases.
건강위험
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
화재위험
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
A poison. May decomposeexplosively if heated above 190°C. When heated todecomposition it emits toxic fumes of NOx.
잠재적 노출
The nitrotoluenes are used in the
production of toluidines and other dye intermediates.
All isomers are used in manufacture of agriculture and
rubber chemicals and in various dyes.
운송 방법
UN1664 Nitrotoluenes, (o-; m-; p-), Hazard
Class: 6.1; Labels: 6.1-Poisonous materials.
비 호환성
Decomposes on contact with strong oxidizers;
strong acids; reducing agents; strong bases; ammonia,
amines producing toxic fumes, causing fire and explosion
hazard. Heat above 190C may cause explosive decomposition.
Attacks some plastics, rubbers, and coatings.
폐기물 처리
Controlled incineration-care
must be taken to maintain complete combustion at all
times. Incineration of large quantities may require scrubbers
to control the emission of nitrogen oxides.
