|
When chlorosilanes come into contact with water, they generate hydrogen chloride. The silicon then bonds with the remaining hydroxyl group, creating a silol group similar to alcohol. This silol group may eventually bond with a solid oxide surface or react with another chlorosilane or silol molecule. In these instances, the oxygen atom acts as a bridge between two silicon atoms, similar to the ether linkage found in organic chemicals and identical to the bonding in silicon dioxide.

| Application |
|
Organic chlorosilanes are commonly utilized as coatings for silicon and glass surfaces and in the manufacturing of silicone (polysiloxane) polymers.
Methyl chlorosilanes contain one to three methyl groups. In the case of dichlorodimethylsilane, there are two available chlorine atoms, allowing for a reaction with excess water to form a linear chain of ether-like connections between silicon atoms. Similar to polyethers, these flexible connections result in the formation of a rubbery polymer known as polydimethylsiloxane (PDMS). Trichloromethylsilane can induce branching and cross-linking in PDMS molecules, while chlorotrimethylsilane is used to terminate backbone chains, thereby limiting the molecular weight. |
