General description

Octadecylsilane is an organosilicon compound that consists of a long-chain hydrocarbon (18 carbons) bonded to a silicon atom through a carbon-silicon bond. It is widely used in various applications due to its high surface activity, making it an excellent adsorbent for non-polar organic compounds. It is also used as a surface modifier or coating agent.

Application

Octadecylsilane can be used as a modifying agent for montmorillonite clay nanoparticles, which are used as a filler material in the synthesis of poly(methyl methacrylate) (PMMA)/silylated montmorillonite composites.

In this study a nano-electrospray emitter is constructed by precisely positioning entrapped octadecylsilane (ODS) particles within a photoinitiated polymer at the exit aperture of a capillary. Following poly-merization, the microsphere/polymer hybrid material is able to withstand pressures greater than 4000

Simple, sensitive, and reproducible off-line solid-phase microextraction and liquid chromatography (SPME/LC) methods are described for the determination of seven anticonvulsants and tricyclic antidepressants in human plasma. Factorial design and simplex methodology were applied in the optimization of the SPME procedure
