Aniline, also known as aniline, aniline oil, aminobenzene, formula: C6H7N. Colorless oily liquid. Melting point, boiling point , relative density, relative molecular weight 93.128, heated to Slightly soluble in water, soluble in ethanol, ether and other organic solvents.
Aniline is one of the most important amines. Mainly used in the manufacture of dyes, medicines, resins, rubber vulcanization accelerators and so on. It can also be used as a black dye. Its derivative methyl orange can be used as an indicator for acid-base titration.
Aniline is one of the most important intermediates in dyestuff industry. It can be used to produce acid ink blue G, acid medium BS, acid tender yellow, direct orange, direct pink, indigo, dispersed yellow brown, Cationic Pink FG and reactive brilliant red X-SB, etc. In organic pigments, it can be used to produce golden red, golden red g, large red powder, phenol cyanine red, oil-soluble black, etc. In printing and dyeing industry, it is used to dye aniline black; in pesticide industry, it is used to produce many pesticides and fungicides, such as DDV, herbicide and poisonous oxalamine; aniline is an important raw material of rubber additives, used to produce antioxidant A, antioxidant butyl, antioxidant RD, etc. It can also be used as raw material of pharmaceutical sulfonamides for the production of spices, plastics, varnishes, film, etc. As stabilizers in explosives, explosion-proof agents in gasoline and as solvents.
Aniline is an important raw material for pesticide production. N-alkyl aniline, alkyl aniline, o-nitroaniline and cyclohexylamine can be derived from aniline. It can be used as intermediate of fungicides such as dichlorfon sodium, seed dressing, triazophos, pyridazine thiophos, quinazole, herbicide methachlor, cyclazinone, imidazoquinolinic acid, etc.
It causes methemoglobinemia and liver, kidney and skin damage.
In the short term, methemoglobinemia occurs first in those who absorb or inhale a large amount of aniline in the skin. The symptoms are cyanosis, blue brown in tongue, lips, finger nails, cheeks and ears, lead-gray in skin and mucosa, dizziness, headache, fatigue, chest tightness, palpitation, shortness of breath, loss of appetite, nausea, vomiting and even disturbance of consciousness.
Long-term low concentration exposure can cause toxic liver disease.
Health hazards: This product mainly causes methemoglobinemia, hemolytic anemia and liver and kidney damage. Easy to absorb through skin. Acute poisoning: The patient's lips, fingers and ears are cyanotic, with headache, dizziness, nausea, vomiting, finger numbness, trance, etc.
It is harmful to the environment and can cause pollution to the water body.
