General description

Dichloromethylsilane is a tetrahedral organosilicon compound. It is used as a silane coupling agent to synthesis the hydrophilic and hydrophobic silica nanoparticles. It is also used in the synthesis of polysilanes, which are precursors to silicon carbide.

Application


  • A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes - Discusses a method for synthesizing Methylmonochlorosilanes, showing potential for varied applications in chemical synthesis (Y Naganawa et al., 2020).

  • Polymerization of methylsilylenes into polymethylsilanes or polycarbosilanes after dechlorination of dichloromethylsilanes. - Investigates the polymerization of methylsilylenes, offering insights into the production of polymethylsilanes or polycarbosilanes from Dichloromethylsilanes (Y Tian et al., 2016).

  • Synthesis of low viscosity of polymethylhydrosiloxane using monomer of dichloromethylsilane - Focuses on producing low-viscosity polymethylhydrosiloxane through hydrolysis-condensation of Dichloromethylsilane, significant for various industrial applications (VF Arini et al., 2022).
