Chemical Properties

N-Dodecytrimethoxysilane has a boiling point of 281°C and a melting point of -44°C. It is soluble in organic solvents such as ethanol, acetone, and benzene, but insoluble in water. Its refractive index is 1.424, and its density is 0.89 g/cm³ at 25°C.

The chemical formula of n-dodecyltrimethoxysilane is C15H34O3Si, and its CAS number is 3069-21-4. It is a stable compound that does not react with water, acids, or bases under normal conditions. However, it can hydrolyze slowly in the presence of moisture, forming a silanol group on the surface of the substrate.

Applications

N-Dodecytrimethoxysilane is a versatile silane coupling agent that can be used in a wide range of applications, including:

1. Surface modification of inorganic materials

N-Dodecytrimethoxysilane can be used to modify the surface properties of inorganic materials such as silica, alumina, and glass. It can improve the wetting, dispersibility, and adhesion of these materials, making them more compatible with organic matrices. This can lead to improved mechanical, thermal, and chemical properties of the composite materials.

2. Adhesion promoter for coatings and adhesives

N-Dodecytrimethoxysilane can be used as an adhesion promoter for coatings and adhesives. It can improve the adhesion between the substrate and the coating or adhesive, resulting in better durability and performance. It can also reduce the surface tension of the coating or adhesive, making it easier to apply and spread evenly.

3. Surface modifier for textiles and fibers

N-Dodecytrimethoxysilane can be used as a surface modifier for textiles and fibers. It can improve the hydrophobicity, softness, and anti-static properties of the fibers, making them more comfortable to wear and easier to process. It can also enhance the dyeability and printability of the fibers, resulting in brighter and more vibrant colors.

4. Anti-corrosion agent for metal surfaces

N-Dodecytrimethoxysilane can be used as an anti-corrosion agent for metal surfaces. It can form a protective film on the surface of the metal, preventing it from reacting with moisture and oxygen in the environment. This can extend the service life of the metal and reduce maintenance costs.

5. Surfactant for emulsions and suspensions

N-Dodecytrimethoxysilane can be used as a surfactant for emulsions and suspensions. It can improve the stability and homogeneity of the emulsion or suspension, preventing the particles from settling or agglomerating. This can lead to better product quality and consistency.

Conclusion

N-Dodecytrimethoxysilane is a versatile silane coupling agent that can be used in a wide range of applications. Its unique structure and chemical properties make it an excellent surface modifier and coupling agent for organic and inorganic materials.
