Description
Triethoxyoctylsilane is a monomeric medium-chain alkylfunctional silane, which is a clear, colorless liquid that is soluble in common non-polar organic solvents. It is an alkoxide organosilane with four ethyl ester sidechains and is used as a self-assembled monolayer, providing a hydrophobic coating with low surface energy. The water contact angle for this compound is in the range of 150-170°.
Uses
1. Used in Surface Modification:
Triethoxyoctylsilane is used as a surface modifier to generate hydrophobicity on various materials such as concrete, glass, inorganic pigments, or mineral fillers. This property makes it useful for creating water-repellent surfaces and improving the durability and resistance of these materials against environmental factors.
2. Used in Water Repellent Products:
When diluted with an appropriate solvent, Triethoxyoctylsilane 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. This results in treated substrates becoming hydrophobic while retaining their original appearance.
3. Used in Solid-Stabilized Emulsions:
Triethoxy(octyl)silane is a hydrophobization agent used to limit coalescence in solid-stabilized emulsions. This application is particularly relevant in the chemical and pharmaceutical industries, where stable emulsions are crucial for various processes and formulations.
4. Used in Coatings and Sealants:
Due to its hydrophobic nature and ability to form a low surface energy coating, Triethoxyoctylsilane can be utilized in the development of coatings and sealants for various applications. These coatings can provide protection against water, stains, and other environmental factors, making them suitable for use in construction, automotive, and other industries where durable and long-lasting protection is required.
Check Digit Verification of cas no
The CAS Registry Mumber 2943-75-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2943-75:
(6*2)+(5*9)+(4*4)+(3*3)+(2*7)+(1*5)=101
101 % 10 = 1
So 2943-75-1 is a valid CAS Registry Number.

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.
