Dichlorodiéthylsilane

Description :

Dichlorodiéthylsilane, avec le numéro CAS 1719-53-5, est un composé organosiliconé caractérisé par ses deux groupes éthyles et deux atomes de chlore attachés à un atome de silicium. Il s'agit généralement d'un liquide incolore à jaune pâle avec une odeur piquante. Ce composé est connu pour sa réactivité, en particulier lors de l'hydrolyse, où il peut réagir avec l'eau pour produire du silanol et de l'acide chlorhydrique. Dichlorodiéthylsilane est principalement utilisé comme précurseur dans la synthèse de polymères de silicone et comme agent de couplage dans divers processus chimiques. Sa structure chimique lui permet de participer à des réactions de réticulation, ce qui le rend précieux dans la production d'élastomères et de résines en silicone. En raison de la présence de chlore, il peut également présenter une toxicité et nécessite une manipulation prudente pour éviter l'inhalation ou le contact avec la peau. Un stockage approprié dans un endroit frais et sec, à l'abri de l'humidité, est essentiel pour maintenir sa stabilité et prévenir les réactions indésirables.

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.
