Uses

Used as a gasoline additive to increase the octane number, and can also be cracked to produce isobutylene, used as a gasoline additive, with excellent anti-knock properties. It has good miscibility with gasoline, little water absorption and no pollution to the environment. As a raw material for organic synthesis, high-purity isobutylene can be produced.

Hazard category

Class 3.1 highly flammable liquid

Fire-fighting measures

Fire fighting method: 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 instrument in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately.

Fire extinguishing agent: alcohol-resistant foam, dry powder, carbon dioxide, sandy soil.

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. Seek medical attention.

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

Packaging, storage, transportation

8. Packed in a paint bucket, 150kg/drum, stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The temperature of the warehouse should not exceed 37℃. Keep the container tightly closed. should be kept away from oxidizer, do not store together. 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.
