三甲基铝是一种常用的有机化学试剂，常用于有机合成、催化剂和表面处理等领域。然而，三甲基铝在使用过程中也存在一定的安全风险。因此，了解三甲基铝的MSDS（材料安全数据表）是非常必要的。

以下是三甲基铝的MSDS英文版：

Product name: Trimethylaluminum

CAS No.: 75-24-1

Molecular formula: C3H9Al

Molecular weight: 72.10 g/mol

Appearance: Colorless liquid

Odor: Pungent, sweet odor

Melting point: -103.5°C

Boiling point: 125.5°C

Density: 0.864 g/mL at 25°C

Solubility: Reacts with water and alcohols

Hazards identification:

- Highly flammable liquid and vapor

- Reacts violently with water, producing flammable gas

- May ignite spontaneously in air

- May cause severe skin burns and eye damage

- May cause respiratory irritation and damage

- May cause liver and kidney damage

First aid measures:

- In case of inhalation: Move to fresh air and seek medical attention if breathing difficulties occur.

- In case of skin contact: Remove contaminated clothing and wash affected area with plenty of water for at least 15 minutes. Seek medical attention if irritation or burns occur.

- In case of eye contact: Rinse eyes thoroughly with water for at least 15 minutes, lifting upper and lower eyelids. Seek medical attention immediately.

- In case of ingestion: Do not induce vomiting. Seek medical attention immediately.

Firefighting measures:

- Extinguishing media: Use carbon dioxide, foam, dry chemical or water spray to extinguish fires.

- Special hazards: May produce toxic fumes when heated or exposed to flames. Use water spray to cool containers.

- Protective equipment: Wear appropriate protective clothing and self-contained breathing apparatus.

Handling and storage:

- Avoid contact with water, alcohols, and other reactive substances.

- Store in a cool, dry, well-ventilated area away from sources of heat, ignition and direct sunlight.

- Keep container tightly closed and upright.

Overall, it is important to handle and store trimethylaluminum with care and follow the safety guidelines outlined in the MSDS. Any questions or concerns should be directed to a qualified professional.
