디메틸디클로로실란 C화학적 특성, 용도, 생산
화학적 성질
Colorless to brown liquid물리적 성질
mp ?76°C; bp 70–71°C; d 1.064 g cm?3.용도
Dichlorodimethylsilane can be used as additive for pinacol cyclization; protecting group for diols and carbonyl compounds;precursor for a wide variety of siliconbased reagents.Dichlorodimethylsilane (1) allows clean pinacol cyclization of a keto aldehyde to occur without competition from an aldol reaction (eq 1).
생산 방법
Produced by the action of silicon on methyl chloride in presence of copper catalyst, or by Grignard reaction from methyl chloride and silicon tetrachloride.일반 설명
A colorless fuming liquid with a pungent odor. Flash point 16°F. Vapor and liquid may cause burns. Denser than water. Vapors heavier than air.반응 프로필
Chlorosilanes, such as Dichlorodimethylsilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.건강위험
Inhalation irritates mucous membranes. Severe gastrointestinal damage may occur. Vapors cause severe eye and lung injury. Upon short contact, second and third degree burns may occur.화재위험
Vapor may explode if ignited in an enclosed area. Reacts vigorously with water to generate hydrogen chloride. Hydrogen chloride and phosgene gases may be formed upon heating or in fire. Runoff to sewer may create fire or explosion hazard.Safety Profile
Poison by ingestion and intraperitoneal routes. Moderately toxic by inhalation. A skin and severe eye irritant. Violent reaction on contact with water. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES.Purification Methods
Other impurities are chlorinated silanes and methylsilanes. Fractionate it through a 3/8in diameter 7ft Stedman column (p 11) rated at 100 theoretical plates at almost total reflux. See purification of MeSiCl2. Solutions in heptane, 1,1,1-trichloroethane or 1-chloronaphthalene are used for the silanization of glassware and pipettes.
