Ethyltrichlorosilane

Description:
Ethyltrichlorosilane, with the CAS number 115-21-9, is an organosilicon compound characterized by its silane structure, where a silicon atom is bonded to three chlorine atoms and one ethyl group. This colorless to pale yellow liquid is known for its reactivity, particularly in hydrolysis, where it reacts with water to produce hydrochloric acid and silanol compounds. Ethyltrichlorosilane is primarily used as a precursor in the synthesis of various silicon-containing materials, including siloxanes and silicone polymers. It is also utilized in surface modification processes and as a coupling agent in the production of composites. The compound has a relatively low boiling point and is volatile, which necessitates careful handling to avoid inhalation or skin contact. Due to its chlorinated nature, it is classified as hazardous, and appropriate safety measures should be taken when working with it, including the use of personal protective equipment and proper ventilation. Overall, ethyltrichlorosilane plays a significant role in the field of materials science and chemical manufacturing.

    CAS:
    <p>Alkyl Silane - Conventional Surface Bonding<br>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.
