Difenildiethoxisilano

Descripción:

Difenildiethoxisilano, con el número CAS 2553-19-7, es un compuesto organosilícico caracterizado por su estructura única, que incluye dos grupos fenilo y dos grupos etóxido unidos a un átomo de silicio. Este compuesto generalmente aparece como un líquido incoloro a amarillo pálido y es conocido por su baja volatilidad y relativamente alta estabilidad. Es soluble en disolventes orgánicos, lo que lo hace útil en diversas aplicaciones, incluyendo como agente de acoplamiento, modificador de superficie y en la formulación de materiales a base de silicona. Difenildiethoxisilano puede participar en reacciones de hidrólisis, lo que lleva a la formación de grupos silanol, que pueden condensarse aún más para formar redes de siloxano. Sus propiedades lo hacen valioso en la producción de recubrimientos, adhesivos y selladores, donde se desean una mejor adhesión y durabilidad. Además, debido a su naturaleza organosilícica, puede exhibir propiedades térmicas y eléctricas únicas, contribuyendo a su utilidad en aplicaciones de materiales avanzados y nanotecnología. Se deben consultar los datos de seguridad para las pautas de manejo y exposición, como con todas las sustancias químicas.

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.
