Storage method

Storage Precautions[19] Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37°C. The packaging must be sealed and must not come into contact with air. They should be stored separately from oxidants, alkalis, etc. and avoid mixed storage. 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.

Synthesis method

It can be prepared by reacting silicon powder with ethyl chloride in the presence of copper catalyst.

Purpose

Used as an intermediate in the manufacture of silicones. [20]
