Dimethyl Silicon Dichloride, also known as Dichlorodimethylsilyl, Dimethyldichlorosilane, Dichlorodimethylsilane, Dimethyl dichlorosilane, and Dichloro(dimethyl)silane, is a commonly used intermediate in the production of silicone compounds. It is a clear, colorless, and highly flammable liquid with a pungent odor. In this article, we will look at the properties, applications, and safety data of Dimethyl Silicon Dichloride and provide a guide for manufacturers looking to use this product in their production processes.

Properties of Dimethyl Silicon Dichloride

Dimethyl Silicon Dichloride is a highly reactive compound that is soluble in organic solvents such as benzene, hexane, and toluene. It has a boiling point of 69°C, a melting point of -111°C, and a density of 1.04 g/cm3. It is a corrosive substance that can cause severe burns on contact with skin, eyes, and mucous membranes. Therefore, proper handling and safety precautions must be taken when working with Dimethyl Silicon Dichloride.

Applications of Dimethyl Silicon Dichloride

Dimethyl Silicon Dichloride is a versatile compound that is used in a variety of applications in the chemical industry. It is commonly used as an intermediate in the production of silicone compounds such as silicone oils, silicone rubbers, and silicone resins. It is also used as a crosslinking agent for polyethylene and as a stabilizer for vinyl chloride resins.

In the production of silicone resins, Dimethyl Silicon Dichloride is reacted with silanol groups to form a linear or branched polymer. These resins have excellent thermal stability, electrical insulation properties, and resistance to weathering, making them ideal for use in coatings, adhesives, and sealants.

Dimethyl Silicon Dichloride is also used as a crosslinking agent for polyethylene. It reacts with the polyethylene to form a crosslinked polymer that has improved physical properties such as increased strength, toughness, and resistance to heat and chemicals. This makes it suitable for use in the production of wire and cable insulation, pipes, and other structural materials.

Safety Data of Dimethyl Silicon Dichloride

Dimethyl Silicon Dichloride is a hazardous substance that can cause severe burns and respiratory irritation if not handled properly. It is highly flammable and can form explosive mixtures with air. Therefore, it should be stored and handled in a well-ventilated area away from sources of ignition.

Skin contact with Dimethyl Silicon Dichloride can cause severe burns and should be avoided. In case of contact, the affected area should be immediately rinsed with water for at least 15 minutes. Eye contact with Dimethyl Silicon Dichloride can cause severe eye damage or blindness. In case of contact, the affected eye should be immediately flushed with water for at least 15 minutes and medical attention sought.

Inhalation of Dimethyl Silicon Dichloride vapors can cause respiratory irritation, coughing, and shortness of breath. Therefore, adequate ventilation and respiratory protection should be used when working with this substance. Ingestion of Dimethyl Silicon Dichloride can cause severe gastrointestinal irritation and should be avoided.

Conclusion

Dimethyl Silicon Dichloride is a highly reactive and versatile compound that is used in a variety of applications in the chemical industry. It is an essential intermediate in the production of silicone compounds and is commonly used as a crosslinking agent for polyethylene and stabilizer for vinyl chloride resins. However, it is a hazardous substance that requires proper handling and safety precautions to avoid exposure and injury.
