Molecular formula： C₆H₁₉NSi₂

Molecular weight： 161

CAS No.： 999-97-3

Properties

Bosil-999 is characterized by easy hydrolysis and easy reaction with hydroxyl groups to eliminate hydroxyl groups. Widely used as surface treatment to enhance adhesion.

Technical data

Note: the above data is for reference only, cannot be as a technical specification. 

Reactivity

Easy hydrolysis, release NH3, to form HEXAMETHYLDISILAZANE.

In the presence of a catalyst, it reacts with an alcohol or phenol to form trimethylalkoxysilane or trimethylaroxysilane.

Application

Main uses: Can be used for special organic synthesis. Silylation in the synthesis of amikacin, penicillin, cephalosporin, fluorouracil and various penicillin derivatives; It can also be used for the surface treatment of diatomite, silica black, titanium and other powders. The mechanism of action is condensation of silicon-nitrogen bond and silicon-hydroxyl group.

It is used as a bonding agent for photoetching agents in semiconductor industry.

In organosilazane chemistry, it can be used as a chlorine exchange with a chlorosilane monomer to obtain a polysilazane. This method has great advantages over the direct ammonia method in synthesis.

The product can be used for the surface treatment of mineral powder and glass fiber, such as the treatment of SiO2 powder, etc. When used for surface treatment, water, ethanol, etc., is commonly mixed as a medium; Used to add to dealcoholized RTV1 silicone rubber to improve its storage stability and other properties; It can also be used in special synthesis.
