3-Chloropropyltrichlorosilane : Guide

3-Chloropropyltrichlorosilane has an irritating odor and is the basic monomer of silane coupling agent. Hydrolysis releases hydrogen chloride and generates the corresponding condensate. The vapor and liquid can cause skin burns, inhalation is toxic. Reacts with anhydrous ethanol, releasing hydrogen chloride and generating 3-chloropropyltriethoxysilane.

The chlorine atom in the C-Cl bond within the molecule can be replaced by hydroxyl, amino, and carboxyl groups through classical organic chemical reactions. It can be produced by reacting trichlorosilane with allyl chloride in the presence of a platinum catalyst. It can also be produced by reacting propyltrichlorosilane with thionyl dichloride in the presence of benzoyl peroxide catalyst. Used to synthesize silicone intermediates, silane coupling agents and polymers.
