[2-(Chlorodimethylsilyl)ethyl]benzene

Description:

[2-(Chlorodimethylsilyl)ethyl]benzene, with the CAS number 17146-08-6, is an organosilicon compound characterized by the presence of a chlorodimethylsilyl group attached to an ethylbenzene moiety. This compound typically exhibits a clear to pale yellow liquid form at room temperature. It is known for its reactivity due to the presence of the chlorosilane functional group, which can participate in various chemical reactions, including nucleophilic substitutions and coupling reactions. The compound is generally hydrophobic, owing to its hydrocarbon structure, and may have moderate volatility. Its applications can be found in the fields of organic synthesis, materials science, and as a potential intermediate in the production of silicone-based materials. Safety considerations include handling precautions due to its chlorinated nature, which may pose risks of irritation or toxicity. Proper storage in a cool, dry place, away from moisture and incompatible substances, is essential to maintain its stability and integrity.

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.
