hydroxytrimethylsilane Chemical Properties,Usage,Production

Description

Trimethylsilanol has strong acidity compared with the corresponding carbon alcohols, can react with tetrahydrolithium aluminum, Si-OH bond can be reduced Si-H bond, can be used as a blocking agent for straight-chain polysiloxanes with hydrophobicity, it is the most important intermediate in the preparation of organosilicon alcohol salts and all kinds of polysiloxanes products including silicone oils, silicone rubbers and silicone resins, etc, and it has a wide range of application prospects.

Chemical Properties

Colorless clear liquid

Uses

Trimethylsilanol used as a hydrophobic coat on silicate surfaces. Used as an as an antimicrobial agent.

Synthesis

Trimethylsilanol is produced by hydrolysis of trimethylchlorosilane.

Toxics Screening Level

The initial risk screening level (IRSL) for Trimethylsilanol is 65 μg/m3 based on an annual averaging time.
