Properties of Propyltrimethoxysilane
Propyltrimethoxysilane exhibits several unique properties that make it an excellent choice for various applications. Some of the key properties of propyltrimethoxysilane are:
- Molecular weight: 160.27 g/moln- Boiling point: 155-157°Cn- Melting point: -102°Cn- Density: 0.906 g/cm3n- Refractive index: 1.390n- Flash point: 40°Cn- Solubility: Soluble in common organic solvents, such as ethanol, acetone, and toluene
One of the significant properties of propyltrimethoxysilane is its ability to hydrolyze in the presence of water or moisture, forming a silanol group (-Si-OH) and methanol. The hydrolysis reaction is exothermic and can be accelerated by acidic or basic conditions. The silanol group can then undergo condensation reactions with other silanol or alkoxysilane molecules, forming a crosslinked network of siloxane bonds (-Si-O-Si-).
