Trichlorovinylsilane (CAS 75-94-5) is a significant organosilicon compound with widespread use in various industrial applications, primarily as a coupling agent and a chemical intermediate. For professionals working with this substance, a thorough understanding of its properties, alongside safe handling and storage protocols, is paramount to ensure operational efficiency and safety. This article aims to provide a detailed overview of Trichlorovinylsilane, covering its key characteristics and essential best practices.

Physically, Trichlorovinylsilane is described as a colorless liquid. Its molecular formula is C2H3Cl3Si, and it has a molecular weight of approximately 161.49 g/mol. Key physical properties include a melting point of -95°C and a boiling point of 90°C. The vapor density is greater than air, meaning its vapors can accumulate in low-lying areas, posing a potential hazard in enclosed spaces. Its density is around 1.27 g/mL at 25°C.

Chemically, Trichlorovinylsilane exhibits significant reactivity, particularly with moisture. It is described as being moisture-sensitive and reacts rapidly with water and protic solvents, liberating hydrogen chloride gas. This characteristic necessitates careful handling to prevent premature decomposition or hazardous reactions. The compound is also prone to polymerization, often requiring stabilizers or specific storage conditions to maintain its integrity.

Due to its reactivity, proper storage of Trichlorovinylsilane is critical. It should be stored in a cool, dry place, away from direct sunlight and sources of ignition. Maintaining an inert atmosphere, such as under nitrogen, is often recommended to prevent contact with atmospheric moisture. Containers must be kept tightly closed to avoid contamination and reaction with ambient air. Understanding the trichlorovinylsilane CAS 75-94-5 properties related to storage and stability is key to its effective use.

Handling Trichlorovinylsilane requires strict adherence to safety guidelines. As it can cause severe burns to skin and eyes upon contact, appropriate personal protective equipment (PPE) must be worn, including chemical-resistant gloves, safety goggles or a face shield, and protective clothing. Inhalation of vapors can irritate mucous membranes and the respiratory tract. Therefore, operations involving Trichlorovinylsilane should ideally be conducted in well-ventilated areas or under fume hoods. Emergency eyewash stations and safety showers should be readily accessible.

For manufacturers and researchers looking to procure this chemical, seeking out suppliers who provide detailed Material Safety Data Sheets (MSDS) or Technical Data Sheets (TDS) is advisable. These documents offer comprehensive information on hazards, handling, storage, and emergency procedures. When you buy Trichlorovinylsilane, ensure you receive the latest safety and handling information.

In conclusion, Trichlorovinylsilane is a valuable chemical with specific properties that necessitate careful management. By understanding its physical and chemical characteristics and implementing robust handling and storage practices, industries can safely and effectively harness the benefits of Trichlorovinylsilane for various applications, from advanced composites to specialized chemical syntheses.
