High Purity Methyltrichlorosilane (MTS)

Colorless and transparent liquid, boiling point approximately 66℃, density 1.273g /mL (at 25℃), volatile and decomposes upon contact with water to form hydrochloric acid and white precipitate. It has a low flash point (5°F) and is a flammable liquid. It must be stored strictly in a sealed container away from water.

Physical and chemical properties

  •  Lytic response :Rapid reaction with water to form hydrochloric acid and polysiloxane.

  • Alcoholysis reaction:  Reacts with alcohols to form alkoxysilanes.

  • Reaction with ammonia/ammonia:Formation of amino silane.

  •  Reducibility :Can be reduced to methylsilane (CH₃SiH₃) by lithium aluminum hydride (LiAlH₄)

  •  Heat endurance :It may be cracked at high temperature (> 300°C) to release HCl or form siloxane.





Application

Semiconductor Industry: Precursor for chemical vapor deposition (CVD) of silicon carbide (SiC) films and low-κ dielectric layers.

Silicone Synthesis: Building block for cross-linked silicones, resins, and hydrophobic coatings.

Surface Treatment: Imparts water repellency to glass, ceramics, and fillers.

Fumed Silica Production: Intermediate in manufacturing high-purity silica nanoparticles.

Packaging and Storage

The container is made of 316L stainless steel, There are three size available in capacity:45L, 250L, and 900L, which can hold 45kg, 250kg, and 1000kg respectively. There are two types of specifications for the 1/2" and 1/4" VCR interface valve. We also provide different packaging and interfaces according to the specific requirements of customers, Including ISO-TANK.
