Triethylaluminum CAS 97-93-8

At present, triethylaluminum is the most widely used organic synthesis in the chemical industry, such as the activator of polypropylene plastics and other products. Due to different uses, its purity is also different. Larger domestic chemical companies use triethylaluminum , with storage tanks and devices for triethyl aluminum.

Triethylaluminum is usually stored under the protection of nitrogen double tanks. During production and use, nitrogen is used to pressurize and transport it to the process equipment. The pressure is generally not more than 0.2 MPa. When the production stops, it will return to a no-pressure state. It has good sealing performance, and once it leaks, a fire will occur. Due to the poor effectiveness of traditional fire extinguishing equipment in dealing with triethyl aluminum fires, chemical companies have been worried about the fire safety of such first-level spontaneous combustion fires.

1. Weapons: Before the 1970s, the US military was equipped with liquid column flamethrower. After 1969, the United States has had the intention to use the rocket combustion method to replace the traditional liquid-column fire-breathing method. In the early 1970s, the United States began to transform the XM191 multi-shot portable flamethrower to develop flame weapons. The weapon has been used from drawing design, field experiments, small batch production and battlefield evaluation. It took less than 3 years in total. It was finalized as an M202 flame weapon in the mid-1970s and began to be used by the US Army and Marine Corps. It is now equipped with a slightly improved M202A2 type. The M202 incendiary rocket launcher is composed of a rocket launch tube and a rocket clip. It uses a self-ignitable incendiary triethyl aluminum as fuel and is powered by an M54 rocket engine.
2. Ammunition: The length of the incendiary rocket is 535mm, the warhead is filled with 600g of thickened triethyl aluminum incendiary agent, equipped with a mechanical trigger fuze, and the projectile is driven by an M54 rocket engine. Using this kind of burning agent, it will spontaneously ignite in the presence of air, and it will explode in the presence of water. This not only saves the ignition mechanism, but also increases the difficulty of extinguishing the fire. Even if it is temporarily covered with sand, it will still burn when exposed to air. It also has a certain adhesiveness, which is not easy to remove, and is suitable for combat requirements.
3. Incendiary bombs: aviation bombs, artillery shells, rockets, grenades and grenades with incendiary agents, also known as arson bombs, are mainly used to burn living forces and burn flammable military technical equipment and equipment. It usually consists of projectiles, incendiary agents, explosives or propellants, detonators, fuzes, etc. The burning agent is mostly thermite, yellow phosphorus, napalm, thickened triethyl aluminum and thickened gasoline, etc., which are used to generate high temperature flame and damage the target; Throw to target. In the modern battlefield, incendiary aviation bombs are more commonly used, and mixed incendiary aviation bombs and napalm aviation bombs are commonly used. The former is equipped with thickened triethyl aluminum, the bomb body is small, and the bomb weight is about 10 to 50 kg; the latter is equipped with napalm and yellow phosphorus, and the bomb weight can reach 500 kg. The types of modern incendiary bombs are increasing day by day, and the heat generated by the incendiary and the burning time and other properties are constantly improving. Thickened triethyl aluminum is one of the main raw materials.
