⚗️ Chemical & Physical Properties
Trimethylchlorosilane is a clear, colorless liquid with a pungent odor. It is commonly used in the manufacturing of silicones and as a reagent in organic chemical synthesis.
With a molar mass of 108.63 g/mol and a density of 0.890 g/cm3, Trimethylchlorosilane is significantly heavier and denser than common food items such as water (molar mass of 18.015 g/mol, density of 1.00 g/cm3) and sugar (molar mass of 342.30 g/mol, density of 1.59 g/cm3).
Trimethylchlorosilane has a melting point of -46°C and a boiling point of 66-67°C. This is much lower in comparison to common food items like butter (melting point of 32-35°C, boiling point of 150-160°C) and chocolate (melting point of 29-32°C, boiling point of 110°C).
Trimethylchlorosilane is not soluble in water and has a low viscosity. This contrasts with common food items like salt and sugar which are highly soluble in water, as well as honey and molasses which have higher viscosities.
🏭 Production & Procurement
Trimethylchlorosilane, a key intermediate in the production of silicone polymers, is typically produced through a reaction of chlorotrimethylsilane with sodium in a suitable solvent. This reaction yields Trimethylchlorosilane as the primary product, which can then be further purified through distillation or other separation techniques to reach desired levels of purity.
Trimethylchlorosilane can be procured commercially from various chemical suppliers and manufacturers specialized in silicone production. It is commonly available in liquid form and stored in sealed containers to prevent exposure to moisture and air, which can degrade the compound. Transport of Trimethylchlorosilane is typically done using appropriate chemical containers, and care must be taken to adhere to strict safety guidelines to prevent leakage or accidental exposure during handling.
Furthermore, due to its reactive nature and potential hazards, Trimethylchlorosilane should be handled and transported by trained individuals with proper safety equipment and procedures in place. It is important to follow established guidelines and regulations regarding the storage, handling, and disposal of Trimethylchlorosilane to ensure safety and prevent any adverse effects on human health and the environment.
⚠️ Safety Considerations
Safety considerations for Trimethylchlorosilane are paramount due to its highly flammable nature and reactivity with water and air. When handling this chemical, it is crucial to wear appropriate personal protective equipment, including gloves, goggles, and a lab coat. Additionally, Trimethylchlorosilane should only be used in a well-ventilated area to minimize the risk of exposure to harmful vapors. Proper storage and handling procedures should be strictly followed to prevent accidents or spills that could lead to fires or chemical burns.
Trimethylchlorosilane is classified as a highly flammable liquid and vapor, posing a serious fire hazard. It is also corrosive to metals, with the potential to cause skin and eye irritation upon contact. Inhaling Trimethylchlorosilane vapors can result in respiratory irritation and damage to the lungs. In case of fire, water should not be used to extinguish the flames, as it may only spread the fire further. Proper firefighting equipment and techniques should be employed to safely contain and extinguish any fires involving Trimethylchlorosilane.
Precautionary statements for Trimethylchlorosilane include storing the chemical in a cool, dry, well-ventilated area away from incompatible materials. Mixing Trimethylchlorosilane with water can cause violent reactions, so it should be added to water slowly and with caution. In case of skin or eye contact, immediate medical attention should be sought, with contaminated clothing removed and washed before reuse. Handling of Trimethylchlorosilane should be performed by trained personnel following established safety protocols, including spill cleanup procedures and waste disposal methods. Regular safety inspections and training should be conducted to ensure that all individuals working with Trimethylchlorosilane are aware of the potential hazards and know how to mitigate risks effectively.
