Diclorodietilsilano

Descrizione:

Diclorodietilsilano, con il numero CAS 1719-53-5, è un composto organosiliconico caratterizzato dai suoi due gruppi etilici e due atomi di cloro legati a un atomo di silicio. Tipicamente è un liquido incolore o giallo pallido con un odore pungente. Questo composto è noto per la sua reattività, in particolare nell'idrolisi, dove può reagire con l'acqua per produrre silanolo e acido cloridrico. Diclorodietilsilano è utilizzato principalmente come precursore nella sintesi di polimeri di silicone e come agente di accoppiamento in vari processi chimici. La sua struttura chimica gli consente di partecipare a reazioni di reticolazione, rendendolo prezioso nella produzione di elastomeri e resine di silicone. A causa della presenza di cloro, può anche presentare tossicità e richiede una manipolazione attenta per evitare inalazione o contatto con la pelle. Un corretto stoccaggio in un luogo fresco e asciutto, lontano dall'umidità, è essenziale per mantenere la sua stabilità e prevenire reazioni indesiderate.

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.
