CAS 940-41-0

[2-(Trichlorosilyl)ethyl]benzene

Description:

[2-(Trichlorosilyl)ethyl]benzene, with the CAS number 940-41-0, is an organosilicon compound characterized by the presence of a trichlorosilyl group attached to an ethyl chain, which is further connected to a benzene ring. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the presence of the trichlorosilyl functional group, which can readily hydrolyze in the presence of moisture, releasing hydrochloric acid and forming silanol species. Its structure imparts both hydrophobic and lipophilic properties, making it useful in various applications, including as a coupling agent in polymer chemistry and as a precursor in the synthesis of silicone materials. Additionally, the compound's reactivity allows it to participate in cross-linking reactions, enhancing the mechanical properties of materials. Safety precautions should be observed when handling this substance, as it can be corrosive and harmful upon exposure.

Aromatic 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.
