Cas N0. : 999-97-3 Molecular formula : C6H19NSi2
Hexamethyldisilazane, colorless transparent liquid. Easy to hydrolyze, release NH3, generate hexamethyldisilazane. In the presence of a catalyst, it reacts with alcohol or phenol to generate trimethylalkoxysilane or trimethylaryloxysilane. It reacts with anhydrous hydrogen chloride to release NH3 or NH4Cl to generate trimethylchlorosilane. It can be prepared by the reaction between trimethylchlorosilane and NH3. It is used as a surface hydrophobic treatment agent for fumed silica and a reagent for providing N atoms in organic synthesis reactions. It can also be used as an auxiliary agent for silicon carbide fibers to improve the heat resistance and strength of silicon carbide fibers. It can also be used as a coating agent. Anti-settling agent. And for the preparation of organosilicon compounds.

industry
For the production of rubber, medicine. This product is a tail reducing agent that reduces the adsorption activity on the surface of the gas chromatography carrier. It is a pharmaceutical intermediate of amikacin and a protective agent for hydroxyl and amino groups. Specialty organic synthesis. Silanating reagent, can be used for simikacin in production.
medicine
Can be used for special organic synthesis. Silylation during the synthesis of amikacin, penicillin, cephalosporin, fluorouracil and various penicillin derivatives.
mining
It can be used for the surface treatment of diatomite, silica, titanium and other powders, and its mechanism of action is the condensation of silicon-nitrogen bonds with silicon hydroxyl groups.
Used as a bonding aid for photoresists in the semiconductor industry.
In organosilazane chemistry, it can be used for chlorine exchange with chlorosilane monomers to obtain polysilazane. This method has a huge advantage in synthesis over the direct ammonia method.
