CAS 780-69-8

Phenyltriethoxysilane

Description:

Phenyltriethoxysilane, with the CAS number 780-69-8, is an organosilicon compound characterized by its silane structure, which includes a phenyl group and three ethoxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid and is known for its ability to bond with both organic and inorganic materials, making it useful as a coupling agent and surface modifier. It exhibits good thermal stability and hydrophobic properties, which enhance its applicability in various formulations, including coatings, adhesives, and sealants. Additionally, Phenyltriethoxysilane can improve the adhesion of organic polymers to inorganic substrates, such as glass and metals, due to its silane functionality. Its reactivity allows it to undergo hydrolysis in the presence of moisture, leading to the formation of silanol groups that can further polymerize or bond with surfaces. Overall, this compound is valued in industries such as construction, electronics, and materials science for its versatility and effectiveness in enhancing material properties.

Arylsilane Cross-Coupling Agent
The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
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.
