Diphenyldiethoxysilane

Description:

Diphenyldiethoxysilane, with the CAS number 2553-19-7, is an organosilicon compound characterized by its unique structure, which includes two phenyl groups and two ethoxy groups attached to a silicon atom. This compound typically appears as a colorless to pale yellow liquid and is known for its low volatility and relatively high stability. It is soluble in organic solvents, making it useful in various applications, including as a coupling agent, surface modifier, and in the formulation of silicone-based materials. Diphenyldiethoxysilane can participate in hydrolysis reactions, leading to the formation of silanol groups, which can further condense to form siloxane networks. Its properties make it valuable in the production of coatings, adhesives, and sealants, where enhanced adhesion and durability are desired. Additionally, due to its organosilicon nature, it may exhibit unique thermal and electrical properties, contributing to its utility in advanced materials and nanotechnology applications. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.

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.
