CAS 871-92-1

Octylsilane

Description:

Octylsilane, with the CAS number 871-92-1, is an organosilicon compound characterized by its long hydrophobic octyl chain attached to a silicon atom. This compound typically appears as a colorless to pale yellow liquid and is known for its low volatility and high thermal stability. Octylsilane is primarily used as a coupling agent, surface modifier, and in the synthesis of silane-based materials. Its hydrophobic properties make it effective in enhancing the water repellency of surfaces and improving adhesion in various applications, including coatings and sealants. Additionally, octylsilane can participate in chemical reactions, such as hydrolysis, leading to the formation of siloxane networks. Due to its structure, it can also influence the physical properties of polymers and composites, making it valuable in materials science. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may pose health risks if inhaled or ingested.

Mono-substituted Silane Reducing Agent
Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
Trihydridosilane
Silyl Hydrides are a distinct class of silanes that behave and react very differently than conventional silane coupling agents. They react with the liberation of byproduct hydrogen. Silyl hydrides can react with hydroxylic surfaces under both non-catalyzed and catalyzed conditions by a dehydrogenative coupling mechanism. Trihydridosilanes react with a variety of pure metal surfaces including gold, titanium, zirconium and amorphous silicon, by a dissociative adsorption mechanism. The reactions generally take place at room temperature and can be conducted in the vapor phase or with the pure silane or solutions of the silane in aprotic solvents. Deposition should not be conducted in water, alcohol or protic solvents.
