Product Description

Hexamethyldisilazane, colourless transparent liquid. Easily hydrolysed, releasing NH3 and generating hexamethyldisiloxane. In the presence of catalyst, react with alcohol or phenol to form trimethyl alkoxysilane or trimethyl aryloxy silane. Reacts with anhydrous hydrogen chloride, releasing NH3 or NH4Cl to form trimethylchlorosilane. It can be produced by reacting trimethylchlorosilane with NH3. Used as surface hydrophobic treatment agent of fumed silica and reagent to provide N atom in organic synthesis reaction, also used as auxiliary agent of silicon carbide fibre to improve the heat resistance and strength of silicon carbide fibre, and also used as antiprecipitation agent of paint. It is also used for the preparation of organosilicon compounds.

Uses of Hexamethyldisilazane
Hexamethyldisilazane can be used in organosilazane chemistry as a chlorine exchange with chlorosilane monomers to obtain polysilazanes. This method has enormous synthetic advantages over the direct ammonia pass-through method.
Uses
Used in the production of rubber, pharmaceuticals, hydroxyl and amino protectants, and inorganic filler treatments. The product is abatement of gas chromatography carrier surface adsorption of live minus Chemicalbook tailing agent. Speciality organic synthesis. Hexamethyldisilazane is alkaline silanation protective agent, used in the synthesis of ciamin kanamycin, amikacin, penicillin, cephalosporin, fluorouracil and a variety of penicillin derivatives and other synthetic processes in the methylsilane alkylation. Surface treatment of diatomaceous earth, silica, titanium and other powders. Binding aid for photolithography etching agent in semiconductor industry.
