Uses

It is mainly used for the production of anion-effect exchange resin, also as a solvent and special fuel. Its solubility is stronger than ether and acetone, and methanol and azeotropic mixture can dissolve nitrocellulose with high nitrogen content. However, due to its strong anesthetic properties, its vapor is not suitable for use as a general solvent. It is usually used as a solvent for special sonication. It is also used in perfume manufacturing and production of artificial resins, as the reaction medium of Grignard reaction and Rapa (synthesis) reaction.

Hazard category

3.2 Class flammable liquid

Fire-fighting measures

It can easily cause combustion when exposed to high heat, open flames and strong oxidants. Violent reaction with oxidant. Extinguishing agent: Alcohol-resistant foam, carbon dioxide, dry powder and sand. Extinguishing fire with water is ineffective. Move the container from the fire scene to an open place as much as possible. Keep the fire container cool by spraying water until the fire is over. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately.

Emergency treatment

Skin contact: Take off contaminated clothing and wash skin thoroughly with soap and water.

Eye contact: Lift the eyelid and rinse with running water or saline. Seek medical attention.

Inhalation: quickly leave the scene to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention

Ingestion: Drink enough warm water, induce vomiting, and seek medical attention.

Packaging, storage, transportation

Packed in plastic drums, with a net weight of 170kg/drum, stored in a cool, ventilated warehouse, away from fire and heat sources. The storage temperature should not exceed 29℃. Keep the container tightly closed. It should be stored separately from oxidants and acids, and avoid mixed storage. Do not store in large quantities or for long periods of time. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
