Tricloroctadecil silano

Descrizione:

Tricloroctadecil silano, con il numero CAS 112-04-9, è un composto organosiliconico caratterizzato dalla sua lunga catena idrofobica di ottadecil e da tre sostituenti clorurati attaccati a un atomo di silicio. Questo composto appare tipicamente come un liquido incolore o giallo pallido ed è noto per la sua bassa volatilità e alta stabilità in varie condizioni. Viene utilizzato principalmente come agente di accoppiamento silanico, migliorando l'adesione dei materiali organici ai substrati inorganici, il che è particolarmente prezioso in rivestimenti, sigillanti e adesivi. La presenza della catena di ottadecil conferisce proprietà idrofobiche, rendendolo efficace in applicazioni idrofobe. Inoltre, la natura clorurata del composto consente una maggiore reattività chimica, permettendogli di legarsi a varie superfici. Tricloroctadecil silano è utilizzato anche nella modifica delle superfici per migliorare la loro compatibilità con i materiali organici, migliorando così le prestazioni in varie applicazioni industriali. Devono essere osservate precauzioni di sicurezza quando si maneggia questo composto, poiché può essere pericoloso a causa dei suoi atomi di cloro reattivi.

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.
