CAS 141-57-1

Propyltrichlorosilane

Description:

Propyltrichlorosilane, with the CAS number 141-57-1, is an organosilicon compound characterized by its trichlorosilane functional group attached to a propyl group. It is typically a colorless to pale yellow liquid with a pungent odor. This compound is known for its reactivity, particularly in hydrolysis, where it reacts with water to produce hydrochloric acid and silanol, leading to the formation of siloxane networks. Propyltrichlorosilane is primarily used as a silane coupling agent, enhancing adhesion between organic materials and inorganic substrates, and is valuable in the production of silicone polymers and coatings. It is also utilized in the synthesis of various silane derivatives. Due to its chlorinated nature, it poses certain hazards, including corrosivity and potential environmental impacts, necessitating careful handling and storage. Safety measures should be observed to prevent exposure, as it can cause irritation to the skin, eyes, and respiratory system. Overall, propyltrichlorosilane is an important compound in materials science and chemical manufacturing.

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.
