Hazard Information

Chemical Properties

Colorless transparent liquid

Uses

TMPS can also be used in the preparation of polytrimethoxyphenylsilane (PTMS) that facilitates the removal of graphene after chemical vapor deposition (CVD). Molecularly imprinted sol gels can be synthesized by using TMPS for the fabrication of localized surface plasmon resonance (LSPR).

Uses

An organosilicate compound for nanoelectronics and material science research.

Uses

Phenyltrimethoxysilane is used for nanoelectronics and material science research. It is used as crosslinking agent for silicone resin and to produce polymer organic silicon compound.

General Description

Trimethoxyphenylsilane (TMPS) is an organotrialkoxysilane that is used as a functional monomer in the sol-gel processing.

Flammability and Explosibility

Flammable

Purification Methods

Fractionate it through an efficient column but note that it forms an azeotrope with MeOH which is a likely impurity. [Kantor J Am Chem Soc 75 2712 1953 Beilstein 16 IV 1556.]

Advantages

The polymer molecule generated from phenyltrimethoxysilane contains a rigid hydrophobic group benzene ring and a water-permeable and breathable silica chain. It has surface activity and weather resistance and can be used as an additive in the coating industry, phenyl silica. Introducing chain links can significantly improve thermoelasticity, mechanical properties, and resin adhesion. Therefore, phenyl silicone resin is widely used as high-temperature-resistant electrical insulating paint, high-temperature-resistant coatings, and molding packaging materials.

Toxics Screening Level

The initial threshold screening level (ITSL) for phenyltrimethoxysilane is 60 μg/m3 based on an annual averaging time.
