Methyltrimethoxysilane Usage And Synthesis
Application Methyltrimethoxysilane is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone. It is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products. Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates the hydrolysis of Methyltrimethoxysilane substantially. 
As a Filler Modifier, Methyltrimethoxysilane is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, glass, cardboard). It may be used pure or in solution to treat fillers, using suitable mixing equipment. It may be necessary to first pre-treat the substrate with water and/or a catalyst. It is also used in the production of silicone resins and condensation-curing silicone rubber, used as an important component in sol-gel systems.
As one of the most common Alkoxy Crosslinkers, Methyltrimethoxysilane has high reactivity that precedes by nucleophilic substitution usually in the presence of acid or base catalysts.
Description 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.
Chemical Properties Colorless clear liquid
Uses 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.
Purification Methods Methyl trimethoxysilane [1185-55-3] M 136.2, b 102o/760mm, d 4 1.3687, n D 1.3711. Likely impurities are 1,3-dimethyltetramethoxy disiloxane (b 31o/1mm) and cyclic polysiloxanes, see methyl triethoxysilane.
