3. Application: aniline is one of the most important intermediates in the dye industry. In the dye industry, aniline can be used to produce acid ink blue G, acid medium BS, acid light yellow, direct orange S, direct pink, indigo, disperse yellow brown, cationic pink FG and reactive brilliant red x-sb. In the field of organic pigments, it is used for making golden luster red, golden luster red g, big red powder, phenolic cyanine red, oil soluble black, etc. Aniline black used in dyeing industry; In the pesticide industry, it is used to produce many insecticides, herbicides, oxalamine, etc. Aniline is an important raw material of rubber auxiliaries, which is used to make antiaging agent nail, antiaging agent tin, antiaging agent, promoter and CA, etc. It can also be used as raw material of sulfonamide medicine, and intermediate of producing flavor, plastic, varnish, film, etc. And can be used as a stabilizer in explosives, explosion-proof agent in gasoline and as a solvent; Other products can also be used to make hydroquinone, 2-phenyl indole and so on. Aniline is an important raw material for the production of pesticides, which can be used as the intermediate of fungicide dirust sodium, seed dressing, insecticide triazophos, herbicide methanolamine, etc.


4. Production and preparation method: nitrobenzene catalytic hydrogenation. (raw materials: benzene + nitric acid + hydrogen), please refer to the relevant information


5. Danger category: toxic substances of class 6.1


6, fire measures: water, foam, carbon dioxide, sand, wear gas masks, in the upwind fire.


7. First aid treatment: skin contact: immediately take off the contaminated clothes, thoroughly wash the skin with soap and water, seek medical advice; Eye contact: immediately lift eyelid, rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes, seek medical advice; Inhalation: quickly remove from site to fresh air. Keep respiratory tract open. If breathing becomes difficult, administer oxygen. If respiratory arrest occurs, immediately give artificial respiration and seek medical advice. Ingestion: drink enough warm water, induce vomiting, seek medical advice.


8, packaging, storage, transportation: can be used, paint iron barrel (200kg/ barrel), plastic barrel (200kg/ barrel), stainless steel tank packaging; Aniline is easy to oxidize and change color when exposed to air and light. It must be sealed, cool, ventilated and protected from light. The storage temperature should not exceed 30℃. As aniline is a highly toxic chemical product, it is necessary to check whether the packaging container is intact and sealed during transportation to ensure no leakage during transportation. Transport as required for dangerous goods.


9. State control and permission: the export shall be issued with the dangerous package certificate and the release certificate issued by the state environmental protection bureau.
