Difenildiethoxisilano

Descrizione:

Difenildiethoxisilano, con il numero CAS 2553-19-7, è un composto organosiliconico caratterizzato dalla sua struttura unica, che include due gruppi fenilici e due gruppi etossilici attaccati a un atomo di silicio. Questo composto appare generalmente come un liquido incolore o giallo pallido ed è noto per la sua bassa volatilità e relativa alta stabilità. È solubile in solventi organici, rendendolo utile in varie applicazioni, tra cui come agente di accoppiamento, modificatore di superficie e nella formulazione di materiali a base di silicone. Difenildiethoxisilano può partecipare a reazioni di idrolisi, portando alla formazione di gruppi silanolo, che possono ulteriormente condensarsi per formare reti di silossano. Le sue proprietà lo rendono prezioso nella produzione di rivestimenti, adesivi e sigillanti, dove si desiderano una migliore adesione e durabilità. Inoltre, a causa della sua natura organosiliconica, può presentare proprietà termiche ed elettriche uniche, contribuendo alla sua utilità in applicazioni di materiali avanzati e nanotecnologia. I dati di sicurezza devono essere consultati per le linee guida di manipolazione ed esposizione, come per tutte le sostanze chimiche.

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.
