CAS 919-31-3

(2-Cyanoethyl)triethoxysilane

Description:

(2-Cyanoethyl)triethoxysilane, with the CAS number 919-31-3, is an organosilicon compound characterized by the presence of a cyanoethyl functional group and three ethoxy groups attached to a silicon atom. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity, particularly in forming siloxane bonds, which makes it useful in various applications such as surface modification, adhesion promotion, and as a coupling agent in composite materials. The cyanoethyl group enhances its ability to interact with polar substrates, while the ethoxy groups facilitate hydrolysis and condensation reactions, allowing for the formation of silane networks. It is soluble in organic solvents and can undergo hydrolysis in the presence of moisture, leading to the formation of silanol groups. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may pose health risks upon exposure. Overall, (2-Cyanoethyl)triethoxysilane is valued in the fields of materials science and surface chemistry for its versatility and functional properties.

2-Cyanoethyltriethoxysilane is a cross-linking agent that is used in coatings and adhesives. It has been shown to have an adsorption mechanism that is dependent on the pH of the solution, with a maximum adsorption at pH 3.2 and a minimum at pH 11. The rate of adsorption is also dependent on the concentration of 2-cyanoethyltriethoxysilane, with higher concentrations leading to faster adsorption rates. Kinetic data for 2-cyanoethyltriethoxysilane has been shown using gravimetric analysis to show that it has an adsorption rate constant of 1.0 × 10^4 s^(-1) at pH 3.2 and 6.5 × 10^4 s^(-1) at pH 11, which are independent of the concentration of this molecule in solution.
