CAS 1719-53-5

Dichlorodiethylsilane

Description:

Dichlorodiethylsilane, with the CAS number 1719-53-5, is an organosilicon compound characterized by its two ethyl groups and two chlorine atoms attached to a silicon atom. It is typically a colorless to pale yellow liquid with a pungent odor. This compound is known for its reactivity, particularly in hydrolysis, where it can react with water to produce silanol and hydrochloric acid. Dichlorodiethylsilane is used primarily as a precursor in the synthesis of silicone polymers and as a coupling agent in various chemical processes. Its chemical structure allows it to participate in cross-linking reactions, making it valuable in the production of silicone elastomers and resins. Due to the presence of chlorine, it can also exhibit toxicity and requires careful handling to avoid inhalation or skin contact. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and prevent unwanted reactions.

Dichlorodiethylsilane

CAS: 1719-53-5

Dichlorodiethylsilane is an aromatic hydrocarbon that is a colorless liquid with a pungent odor. It has been used as a chemical intermediate and in the synthesis of dyes, pharmaceuticals, and other organic chemicals. Dichlorodiethylsilane reacts with hydrogen fluoride to form hydrogen chloride and dichloroethane. The reaction products are acidic due to the presence of hydroxyl groups, which react with water vapor to form hydrochloric acid and alcohols. Dichlorodiethylsilane reacts with nucleophiles such as chlorides or hydroxides to form ether linkages. This compound also reacts with c1-c4 haloalkyls to form chlorinated alkyl groups. Dichlorodiethylsilane is soluble in water, but not in ether or benzene. It is stable at room temperature but decomposes when heated to temperatures above 200°C (392°F).

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.
