Chlorodimethylvinylsilane

Product Overview

Chlorodimethylvinylsilane (CAS 1719-58-0) represents a critical organosilicon compound widely utilized in the synthesis of advanced silicone materials. As a versatile monomer, it plays an indispensable role in the manufacturing of silicone polymers, resins, and various elastomeric products. Our facility produces this chemical under strict quality control standards to ensure consistent performance in downstream applications. This compound is specifically designed for industrial users seeking reliable raw materials for complex chemical synthesis.

This colorless to straw-colored liquid features a reactive vinyl group and a chlorosilane functionality, making it an ideal building block for introducing vinyl functionality into silicone chains. The presence of the vinyl group allows for participation in hydrosilylation reactions, while the chloro group facilitates coupling with hydroxyl-terminated surfaces or other silanols. This dual reactivity profile makes it a preferred choice for chemists designing custom silicone architectures.

Key Physical and Chemical Properties

Understanding the physical characteristics of Chlorodimethylvinylsilane is essential for safe handling and effective formulation. The compound exhibits a boiling point range of 82-83 degrees Celsius and a density of approximately 0.874 g/cm3 at standard conditions. Its refractive index is measured at 1.414, indicating high optical clarity suitable for specialized optical silicone applications. Due to its flash point of -5 degrees Celsius, appropriate safety measures regarding flammability must be observed during storage and transport. The molecular weight is 120.65 g/mol, and the molecular formula is C4H9ClSi.

Industrial Applications

The primary application of this organosilicon monomer lies in the production of silicone polymers. These polymers serve as the foundation for a diverse array of end products, including:

• High-performance silicone oils and lubricants for extreme conditions
• Durable silicone greases for industrial maintenance and protection
• Flexible silicone rubbers used in sealing, gasketing, and molding
• Cross-linking agents for silicone resin systems enhancing durability
• Surface modification agents for improved adhesion properties

Additionally, it functions as a crucial intermediate in the synthesis of other organosilicon substances, enabling chemists to tailor molecular structures for specific performance benchmarks such as thermal stability, weather resistance, and mechanical strength. Its versatility extends to use in composite materials where silicone integration is required for enhanced performance.

Quality Specifications and Assurance

We adhere to rigorous factory standards to guarantee product integrity. Each batch undergoes comprehensive gas chromatography (GC) analysis to verify purity levels. The typical specification ensures a minimum purity of 97.0 percent, with actual test results often exceeding 97.2 percent. The appearance is consistently maintained as a clear to light yellow liquid, conforming to visual inspection standards. Our quality assurance team conducts multiple checkpoints during production to minimize impurities and ensure batch-to-batch consistency.

Packaging Storage and Safety

To maintain stability and safety, Chlorodimethylvinylsilane is packaged in 180 kg drums. Custom packaging solutions are available upon request to meet specific logistical requirements. Storage should be conducted in a cool, well-ventilated area away from moisture and incompatible materials. Proper ventilation is critical due to the potential release of hydrogen chloride upon hydrolysis. We recommend consulting the Safety Data Sheet (SDS) for detailed handling instructions and regulatory compliance information. Personnel should wear appropriate personal protective equipment including gloves and eye protection during handling.
