Trichlorooctadecylsilan

Beschreibung:

Trichlorooctadecylsilan, mit der CAS-Nummer 112-04-9, ist eine organosiliciumverbindung, die durch ihre lange hydrophobe Oktadecylkette und drei Chlorersatzgruppen, die an ein Siliziumatom gebunden sind, gekennzeichnet ist. Diese Verbindung erscheint typischerweise als farblose bis blassgelbe Flüssigkeit und ist bekannt für ihre geringe Flüchtigkeit und hohe Stabilität unter verschiedenen Bedingungen. Sie wird hauptsächlich als Silanvermittler verwendet, um die Haftung organischer Materialien an anorganischen Substraten zu verbessern, was besonders wertvoll in Beschichtungen, Dichtstoffen und Klebstoffen ist. Die Anwesenheit der Oktadecylkette verleiht hydrophobe Eigenschaften, wodurch sie in wasserabweisenden Anwendungen effektiv ist. Darüber hinaus ermöglicht die chlorierte Natur der Verbindung eine weitere chemische Reaktivität, die es ihr ermöglicht, sich mit verschiedenen Oberflächen zu verbinden. Trichlorooctadecylsilan wird auch zur Modifikation von Oberflächen verwendet, um deren Kompatibilität mit organischen Materialien zu verbessern, wodurch die Leistung in verschiedenen industriellen Anwendungen gesteigert wird. Sicherheitsvorkehrungen sollten beim Umgang mit dieser Verbindung beachtet werden, da sie aufgrund ihrer reaktiven Chloratome gefährlich sein kann.

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.
