Tributylchlorosilane Chemical Properties,Usage,Production

Description

Tributylchlorosilane is a silanising agent widely used as a surface modification reagent and coupling agent in various chemical processes. It enhances hydrophobicity and improves adhesion properties by reacting with hydroxyl groups on surfaces to form stable siloxane bonds. Therefore, it is valuable in applications such as coating materials, silicone polymer manufacturing, and reagents for chromatographic analysis. The mechanism is that the chlorosilane group reacts with the surface hydroxyl group, replacing the surface chlorine atom by a covalent bond, while the butyl group provides hydrophobic properties.

Uses

Chlorotri-n-butylsilane is as silylating agent. It can react with bromo-trifluoro-methane, to product tributyl-trifluoromethyl-silane.

Application

Tributylchlorosilane can be used as one of the chlorosilane compounds for the preparation of lithium sulfide. Lithium sulfide is the most important basic raw material in a new type of high-energy and high-safety solid-state lithium-ion battery.
