Tricloroctadecil silano

Descripción:

Tricloroctadecil silano, con el número CAS 112-04-9, es un compuesto organosilícico caracterizado por su larga cadena hidrofóbica de octadecil y tres sustituyentes de cloro unidos a un átomo de silicio. Este compuesto típicamente aparece como un líquido incoloro a amarillo pálido y es conocido por su baja volatilidad y alta estabilidad en diversas condiciones. Se utiliza principalmente como agente de acoplamiento de silano, mejorando la adhesión de materiales orgánicos a sustratos inorgánicos, lo que es particularmente valioso en recubrimientos, selladores y adhesivos. La presencia de la cadena de octadecil otorga propiedades hidrofóbicas, haciéndolo efectivo en aplicaciones repelentes al agua. Además, la naturaleza clorada del compuesto permite una mayor reactividad química, lo que le permite unirse a diversas superficies. Tricloroctadecil silano también se utiliza en la modificación de superficies para mejorar su compatibilidad con materiales orgánicos, mejorando así el rendimiento en diversas aplicaciones industriales. Se deben observar precauciones de seguridad al manipular este compuesto, ya que puede ser peligroso debido a sus átomos de cloro reactivos.

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.
