Dicloreto de dimetilsilano

Descrição:

Dicloreto de dimetilsilano, com o número CAS 75-78-5, é um composto organossilícico caracterizado pela sua fórmula química C2H6Cl2Si. É um líquido incolor a amarelo pálido com um odor pungente, comumente utilizado como intermediário na síntese de polímeros de silicone e como agente de acoplamento de silano. Este composto apresenta dois grupos metila e dois átomos de cloro ligados a um átomo de silício, o que contribui para sua reatividade. Dicloreto de dimetilsilano é conhecido por sua capacidade de reagir com água, liberando ácido clorídrico e formando compostos de silanol, que podem polimerizar ainda mais para formar siloxanos. É moderadamente volátil e pode ser perigoso, exigindo manuseio cuidadoso devido à sua natureza corrosiva e potenciais efeitos à saúde após exposição. Em termos de propriedades físicas, possui um ponto de ebulição relativamente baixo e uma densidade maior que a da água. Devido à sua reatividade e potencial impacto ambiental, devem ser tomadas as medidas de segurança adequadas ao trabalhar com esta substância em ambientes laboratoriais ou industriais.

Bridging Silicon-Based Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
Alkyl Silane - Conventional Surface Bonding
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.

Dichlorodimethylsilane

CAS: 75-78-5

Dichlorodimethylsilane is a chemical compound that belongs to the group of organic compounds that are solids at room temperature. It has been used as a model system for studying the hydrophobic effect, and has also been shown to be an efficient solid catalyst for hydrogenation reactions. Dichlorodimethylsilane can be used in analytical chemistry as it is soluble in water, and it can be used as a reaction solution for potassium dichromate. The reaction mechanism for dichlorodimethylsilane is yet to be determined, but it is believed that the hydroxyl group on one molecule reacts with the hydrogen on another molecule.
