Dichlordiethylsilan

Beschreibung:

Dichlordiethylsilan, mit der CAS-Nummer 1719-53-5, ist eine organosiliciumverbindung, die durch ihre zwei Ethylgruppen und zwei Chloratome, die an ein Siliziumatom gebunden sind, gekennzeichnet ist. Es handelt sich typischerweise um eine farblose bis blassgelbe Flüssigkeit mit einem stechenden Geruch. Diese Verbindung ist bekannt für ihre Reaktivität, insbesondere bei der Hydrolyse, wo sie mit Wasser reagieren kann, um Silanol und Salzsäure zu produzieren. Dichlordiethylsilan wird hauptsächlich als Vorstufe bei der Synthese von Silikonpolymeren und als Kopplungsagent in verschiedenen chemischen Prozessen verwendet. Ihre chemische Struktur ermöglicht es ihr, an Vernetzungsreaktionen teilzunehmen, was sie in der Produktion von Silikonelastomeren und -harzen wertvoll macht. Aufgrund des Vorhandenseins von Chlor kann sie auch Toxizität aufweisen und erfordert eine sorgfältige Handhabung, um Inhalation oder Hautkontakt zu vermeiden. Eine ordnungsgemäße Lagerung an einem kühlen, trockenen Ort, fern von Feuchtigkeit, ist entscheidend, um ihre Stabilität zu erhalten und unerwünschte Reaktionen zu verhindern.

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.
