2943-75-1 Usage

Description

Triethoxyoctylsilane is a monomeric medium-chain alkylfunctional silane. It is a clear colourless liquid and soluble in common non-polar organic solvent. Triethoxyoctylsilane can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers). When diluted with an appropriate solvent, it can be used in the formulation of water repellent products. Upon proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate. Treated substrates are hydrophobic and retain their original appearance.

Chemical Properties

Colorless transparent liquid

Uses

Triethoxy(octyl)silane is a hydrophobization agent used to limit coalescence in solid-stabilized emulsions.

General Description

Triethoxy(octyl)silane (TEOS) is an alkoxide organosilane with four ethyl ester sidechains. It is used as a self-assembled monolayer and provides a hydrophobic coating with low surface energy. The water contact angle is in the range of 150-170°.

Efficient magnetically separable heterogeneous platinum catalyst bearing imidazolyl schiff base ligands for hydrosilylation

Huo, Yingpeng,Hu, Jiwen,Tu, Yuanyuan,Huang, Zhenzhu,Lin, Shudong,Luo, Xiaojiong,Feng, Chao

, (2021/02/06)

Reported herein is a magnetically separable heterogeneous nano catalyst Fe3O4@SiO2-biIMI- PtCl2, which is prepared by firstly applying a SiO2 coating onto readily synthesized magnetite nanoparticles via the hydrolysis condensation of tetraethyl orthosilicate (TEOS) under basic conditions, then modifying it using aminopropyl triethoxysilane and bis(imidazole) aldehyde, and finally incorporating a PtCl2 complex via coordination chemistry. The chemical structure and morphology of the nanocatalyst as well as the valence state and content of platinum within this catalyst were carefully characterized. This catalyst can mediate the hydrosilylation between 1-octene and hydrosilane, with the conversion of 1-octene reaching up to 99%, and it shows good regioselectivity as only β-adducts are identified. In addition, this catalyst can be reused for at least 5 cycles. The hydrosilylation reaction between different olefins and hydrosilanes can also be efficiently mediated by Fe3O4@SiO2-biIMI-PtCl2.

Platinum-Pyridine Schiff base complexes immobilized onto silica gel as efficient and low cost catalyst for hydrosilylation

Huo, Yingpeng,Hu, Jiwen,Liu, Feng,Wu, Jiapei,Zhang, Yikun,Zhang, Yalan,Wang, Qianyi

, p. 812 - 818 (2021/07/25)

A heterogeneous platinum catalyst with tridentate pyridine Schiff base ligands supported on silica gel is reported. The catalyst was fully characterized via FTIR, solid-state 13C NMR spectroscopy, X-ray photoelectron spectroscopy (XPS), N2 adsorption/desorption analysis, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The catalyst showed potential application in mediating hydrosilylation reactions between olefins and hydrosilanes, and it can be reused for at least five cycles.
