Trichlorooctadécylsilane

Description :

Trichlorooctadécylsilane, avec le numéro CAS 112-04-9, est un composé organosiliconé caractérisé par sa longue chaîne hydrophobe d'octadécyle et trois substituants chlorés attachés à un atome de silicium. Ce composé apparaît généralement sous la forme d'un liquide incolore à jaune pâle et est connu pour sa faible volatilité et sa grande stabilité dans diverses conditions. Il est principalement utilisé comme agent de couplage silane, améliorant l'adhésion des matériaux organiques aux substrats inorganiques, ce qui est particulièrement précieux dans les revêtements, les mastics et les adhésifs. La présence de la chaîne d'octadécyle confère des propriétés hydrophobes, le rendant efficace dans les applications déperlant. De plus, la nature chlorée du composé permet une réactivité chimique accrue, lui permettant de se lier à diverses surfaces. Trichlorooctadécylsilane est également utilisé dans la modification des surfaces pour améliorer leur compatibilité avec les matériaux organiques, améliorant ainsi les performances dans diverses applications industrielles. Des précautions de sécurité doivent être observées lors de la manipulation de ce composé, car il peut être dangereux en raison de ses atomes de chlore réactifs.

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.

Trichlorooctadecylsilane

CAS : 112-04-9

Trichlorooctadecylsilane is a model system that consists of a monolayer of octadecyltrichlorosilane particles. The dispersive solid-phase extraction technique can be used to extract analytes from the surface of this particle. This technique involves removing the solvent from a sample by passing it through an adsorbent. The hydrophobic effect, which is the phenomenon that a nonpolar substance is dissolved in a nonpolar solvent, will cause analytes to bind to the hydrophobic surface of octadecyltrichlorosilane particles because they are hydrophobic.
