Beschreibung
Trimethoxy (methyl) silane is an organosilicon compound. It can be
used as a crosslinker in the preparation of polysiloxane polymers.
It can also be used as an acid scavenge used in the formation of
substituted azulenes from allenylsilanes and tropyl?ium
tetrafluoroborate. It can also be used as the precursor for
synthesis of flexible silica aerogels.
Chemische Eigenschaften
Colorless clear liquid
Verwenden
Methyltrimethoxysilane(MTMS) in combination with iron nitrate altered the pore structure dramatically. As the Crosslinking agent of RTV silicone rubber and glass fiber surface treatment agent and talk to agents outside of reinforced plastic laminated products in order to improve the mechanical strength, heat resistance, moisture resistance.
Methyltrimethoxysilane is used as an acid scavenger, for example in the formation of substituted azulenes from allenylsilanes and tropyl-ium tetrafluoroborate.
synthetische
Methyltrimethoxysilane is usually prepared from methyltrichlorosilane and methanol:
CH3SiCl3 + 3 CH3OH → CH3Si(OCH3)3 + 3 HCl
Allgemeine Beschreibung
Trimethoxymethylsilane (MTM) is an organosilicon compound widely used as a precursor for the preparation of silica-based materials, which finds the applications in various fields. Particularly in molecular assembly, linking nano building blocks, and selective synthesis oligosiloxane compounds. It can also be utilized as a crosslinker in the synthesis of polysiloxane polymers.
