CAS 3069-42-9: Octadeciltrimetossisilano

Descrizione:
Octadeciltrimetossisilano, con il numero CAS 3069-42-9, è un composto organosilano caratterizzato dalla sua lunga catena alchilica idrofobica e da tre gruppi metossilici legati a un atomo di silicio. Questa struttura conferisce proprietà uniche, rendendolo un efficace agente di accoppiamento silano e modificatore di superficie. Tipicamente è un liquido incolore o giallo pallido con una viscosità relativamente bassa. La presenza della lunga catena ottadecilica ne aumenta l'idrofobicità, permettendogli di formare monostrati autoassemblati su vari substrati, il che può migliorare le proprietà superficiali come la repellenza all'acqua e la resistenza chimica. Octadeciltrimetossisilano è comunemente utilizzato in applicazioni come rivestimenti, adesivi e sigillanti, così come nella modifica della silice e di altri materiali inorganici per migliorare la compatibilità con i polimeri organici. Inoltre, può facilitare il legame di materiali organici a superfici inorganiche, rendendolo prezioso in varie applicazioni industriali e di ricerca. La corretta manipolazione e conservazione sono essenziali, poiché può reagire con l'umidità, portando al rilascio di metanolo.

  • n-OCTADECYLTRIMETHOXYSILANE

    CAS:
    Alkyl 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. n-Octadecyltrimethoxysilane; Trimethoxyoctadecylsilane; Trimethoxysilyloctadecane Contains 5-10% C18 isomersMelting point: 13-17 °C (55-63 °F)Forms hydrophobic, oleophilic coatingsForms clear, ordered films with tetramethoxysilaneUndergoes oscillatory adsorption to form SAMsTrialkxoy silane

  • Octadecyl-trimethoxysilane

    CAS:
    Octadecyl-trimethoxysilane (OTMS) is a chemical compound that is stable in air, water, and most organic solvents. It can be used for sample preparation, such as the removal of lipids from biological samples. OTMS has been shown to react with hydroxyl groups to form silanol groups. OTMS also reacts with the chinese herb Polygonum multiflorum to form a light-sensitive product that inhibits human serum albumin aggregation. OTMS has been shown to have a particle size of about 25 nm and transport properties similar to those of water. OTMS is also used as a model system in electrochemical impedance spectroscopy and titration calorimetry experiments on ionic liquids.
