Understanding the molecular structure and chemical behavior of key industrial compounds is crucial for innovation and product development. As a dedicated manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. is pleased to share insights into 1,2-Bis(triethoxysilyl)ethane (CAS 16068-37-4). This organosilicon compound, with its unique dipodal structure, offers a wealth of benefits that can elevate the performance of various materials and formulations.

Molecular Architecture and Reactivity

The molecular formula of 1,2-Bis(triethoxysilyl)ethane is C14H34O6Si2, and its IUPAC name is triethoxy(2-triethoxysilylethyl)silane. The defining feature is the presence of two triethoxysilyl groups connected by a short ethylene (-CH2-CH2-) chain. Each triethoxysilyl group contains three ethoxy (-OCH2CH3) functionalities attached to a silicon atom. These ethoxy groups are hydrolyzable, meaning they can react with water, typically in the presence of an acid or base catalyst, to form silanol groups (-Si-OH) and release ethanol.

The general reaction pathway involves:

  1. Hydrolysis: Si-OCH2CH3 + H2O → Si-OH + CH3CH2OH
  2. Condensation: Si-OH + HO-Si → Si-O-Si + H2O (forming siloxane bonds)

Because 1,2-Bis(triethoxysilyl)ethane possesses six such hydrolyzable ethoxy groups, it exhibits a high degree of crosslinking potential. This hexafunctional nature allows it to form dense, three-dimensional siloxane networks (Si-O-Si) upon condensation. These networks are exceptionally stable, contributing to improved thermal stability, mechanical strength, and chemical resistance in the materials where it is incorporated.

Synthetic Routes and Manufacturing Considerations

While specific proprietary synthesis methods vary, the production of 1,2-Bis(triethoxysilyl)ethane typically involves the reaction of chlorosilanes with alcohols. For procurement purposes, understanding that manufacturers like us ensure high purity (often 95% or higher) is key to achieving predictable and reliable results in your applications. The upstream synthesis routes often involve intermediates like vinyltriethoxysilane or related compounds reacting with silicon tetrachloride or other silane precursors under controlled conditions. The efficiency and purity of these synthesis routes directly impact the final product's performance as a coupling agent or crosslinker.

Why Manufacturers Choose This Silane

When research scientists and product formulators seek to buy 1,2-Bis(triethoxysilyl)ethane, they are looking for a reliable way to enhance material properties. Its key advantages include:

  • Versatile Crosslinking: Acts as a potent crosslinker, particularly in silicone-based systems and sol-gel processes, leading to robust polymer architectures.
  • Adhesion Promotion: Effectively bridges organic and inorganic interfaces, enhancing bond strength in applications ranging from industrial coatings to electronic components.
  • Durability Enhancement: The resulting dense siloxane networks offer superior resistance to environmental factors like moisture and chemicals.
