Properties and stability

1. Avoid contact with humid air. Avoid contact with alcohols, oxygen, oxidants, acids, alkalis, and water. It is easy to spontaneously ignite when exposed to air and explode when exposed to water.

2. Wash with plenty of water after contact with human body. During the production process, strict protective measures should be taken, production equipment should be sealed to prevent leakage, and operators should wear protective equipment.
?

Storage method

1. Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30?. Keep container tightly sealed. They should be stored separately from oxidants, acids, alkalis, alcohols, and food chemicals, and avoid mixed storage. It should not be stored in large quantities or for long periods of time. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials. Should be stored under dry nitrogen.

2. This product is prone to violent combustion when exposed to air and reacts violently when exposed to water. Flammable and explosive, must not come into contact with air and water. Packed in steel cylinders, protected by nitrogen. Or dilute it to less than 20%, put it in barrels and protect it with nitrogen seal to prevent leakage. It is safer to use hexane or gasoline to make a 15% to 20% solution.

Synthesis method

1. Aluminum iodine method (sesquimethod) The reaction between ethyl chloride dried by aluminum oxide and aluminum powder in the presence of activator iodine and sesquiethylaluminum chloride produces sesquiethylaluminum chloride. (referred to as sesqui-particle), and then reacted with metallic sodium or sodium chloride to obtain diethyl aluminum chloride.

2. Aluminum-magnesium alloy method: Refined ethyl chloride reacts with aluminum-magnesium alloy that has been ball milled and activated by diethyl aluminum chloride, and the finished product is obtained after evaporation.

3. Direct method: Add triethylaluminum and hydrogen to activated aluminum to react to form diethyl aluminum hydride, and then react with ethylene to form triethylaluminum. Triethylaluminum reacts with aluminum trichloride to form diethylaluminum chloride. Raw material consumption (kg/t), aluminum iodine method aluminum powder ?99.5% 400ethyl chloride ?99% 1460iodine ?99.5% 8 metallic sodium ?99.5% 134.5
