3-Chloropropyltrichlorosilane : Guide
3-Chloropropyltrichlorosilane has a distinct irritating odor and is a key monomer in silane coupling agent production. During hydrolysis, it releases hydrogen chloride and forms the corresponding condensate. Both the vapor and liquid are hazardous, as they can cause skin burns, and inhalation is toxic. 3-Chloropropyltrichlorosilane reacts with anhydrous ethanol, releasing hydrogen chloride and forming 3-chloropropyltriethoxysilane.
The chlorine atom in the C-Cl bond can be replaced by hydroxyl, amino, and carboxyl groups through conventional organic chemical reactions. This compound can be synthesized by reacting trichlorosilane with allyl chloride using a platinum catalyst, or by reacting propyltrichlorosilane with thionyl dichloride in the presence of a benzoyl peroxide catalyst. 3-Chloropropyltrichlorosilane is widely used to produce silicone intermediates, silane coupling agents, and polymers.
