Definition and Overview of Adipic Acid

Identification

Chinese Name: English Name: Molecular Formula:

Adipic Acid;
; Hexanedioic acid; Adipicacid
C ₆ H1 ₀ O ₄

CAS number:

1249

Combustion and explosion hazard:

Flammable. Dust mixed with air can form explosive mixtures, which can cause dust explosions when exposed to open flames or high temperatures.

An exothermic neutralization reaction occurs with alkali. Reacting with sulfides, nitrides, and thiosulfates, releasing active reactions: producing toxic or flammable gases. Reacts with carbonates or percarbonates to produce carbon dioxide, releasing the heat of reaction.

May react violently with strong oxidants. Reacting with strong reducing agents will release hydrogen gas.

Harmful

Taboos:

Oxidants, reducing agents, alkalis.
.

Message

Information

Emergency response to leakage:

Get out of contact. If you feel uncomfortable, seek medical attention. Separate eyelids and rinse with flowing water or saline solution. If you feel uncomfortable, seek medical attention. Remove contaminated clothing and rinse with soap and water. If you feel uncomfortable, seek medical attention. Rinse your mouth, drink water as much as possible, and do not induce vomiting. Seek medical attention. Firefighters must wear full body acid and alkali resistant firefighting suits and air respirators to extinguish fires. Do not directly spray water onto the molten material to avoid serious flowing fires or violent boiling splashes. Extinguishing agent: foggy water, insoluble foam, dry powder, carbon dioxide, sand. Isolate the contaminated area and restrict access. Eliminate all ignition sources. It is recommended that emergency personnel wear dust masks and general work clothes. All equipment used during homework should be grounded. Cut off the leakage source as much as possible. Cover the leaked material with dry sand or other non combustible materials, and then cover it with plastic sheeting to reduce scattering and avoid rain. Collect the leaked material with a clean shovel, place it in a clean, dry container with a loose lid, and move the container away from the leakage area.
