Chlorodimethylvinylsilane: Properties, Applications, and Manufacturing
Chlorodimethylvinylsilane, also known as dimethylvinylchlorosilane or vinylchlorodimethylsilane, is a colorless and flammable liquid with a pungent odor. It belongs to the family of vinylsilanes, which are organosilicon compounds containing a vinyl group attached to a silicon atom. Chlorodimethylvinylsilane is a versatile chemical that finds applications in many industries, including silicone, pharmaceuticals, agrochemicals, and plastics.
Properties of Chlorodimethylvinylsilane
The molecular formula of chlorodimethylvinylsilane is C4H9ClSi, and its molecular weight is 122.67 g/mol. It has a boiling point of 90-92°C and a density of 0.912 g/cm3 at 25°C. Chlorodimethylvinylsilane is soluble in organic solvents such as ethanol, acetone, and benzene but reacts violently with water and strong oxidizing agents. It is a highly reactive compound that undergoes various chemical reactions, including hydrolysis, polymerization, and crosslinking.
Applications of Chlorodimethylvinylsilane
The main applications of chlorodimethylvinylsilane are in the production of silicone polymers and resins. It is a key intermediate in the synthesis of vinyl-functionalized silanes, which are widely used as coupling agents, adhesion promoters, and crosslinkers in silicone-based formulations. Chlorodimethylvinylsilane reacts with other silanes, such as methyldichlorosilane or tetramethoxysilane, to form vinylsilane copolymers that exhibit excellent mechanical, thermal, and electrical properties.
Chlorodimethylvinylsilane is also used in the production of agrochemicals and pharmaceuticals. It can be converted into various derivatives, such as chlorodimethylvinylsilyl-terminated polyethers, that have herbicidal, insecticidal, or fungicidal properties. Chlorodimethylvinylsilane is also a useful building block for the synthesis of biologically active compounds, such as antitumor agents, antiviral agents, and enzyme inhibitors.
In the plastics industry, chlorodimethylvinylsilane is employed as a crosslinking agent for polyethylene and other thermoplastics. It reacts with the polymer chains under the influence of heat or radiation to form a three-dimensional network that improves the mechanical, thermal, and chemical stability of the material. Chlorodimethylvinylsilane-based crosslinked polymers are used in wire and cable insulation, pipe and tubing, and automotive parts.
Manufacturing of Chlorodimethylvinylsilane
Chlorodimethylvinylsilane is manufactured by reacting vinylchloride with dimethyldichlorosilane in the presence of a catalyst, such as copper or aluminum chloride. The reaction takes place at elevated temperatures and pressures and produces chlorodimethylvinylsilane as the main product, along with some by-products, such as dichlorodimethylsilane and trichlorosilane. The crude product is then purified by distillation or fractional crystallization to obtain a high-purity grade of chlorodimethylvinylsilane.
