Usage

General Description

TETRAKIS(2-METHOXYETHOXY)SILANE, also known as TMES, is a colorless, clear liquid that is used as a crosslinking agent in the production of various silicone-based materials. It is a silane coupling agent that is often used to improve the adhesion between organic polymers and inorganic materials such as glass, metal, or ceramic surfaces. TMES is commonly used in the manufacturing of silicone sealants, adhesives, and coatings, as well as in the production of silicone rubber and resins. It is known for its ability to improve the mechanical, thermal, and chemical properties of silicone-based materials, making it a versatile and essential chemical in the silicone industry. However, it is important to handle TMES with caution as it is considered to be toxic and can cause irritation upon contact with skin, eyes, and respiratory system.

Process for preparing low-chloride or chloride-free alkoxysilanes

A process for preparing an alkoxysilane with an acidic chloride content of less than 10 ppm by weight, comprising: reacting a chlorosilane with an alcohol in a water-free and solvent-free phase to form a product mixture containing alkoxysilane and residual acidic chloride, with removal of resultant hydrogen chloride from the product mixture, then adding liquid or gaseous ammonia, in an amount corresponding to a stoichiometric excess, based on the content of acidic chloride, to form an ammonia-containing product mixture, treating the ammonia-containing product mixture at a temperature between 10 and 50 DEG C., wherein the ammonia and acidic chloride undergo neutralization, to form a crude product, and optionally, then separating off a salt formed in the course of neutralization, from the crude product, and recovering the alkoxysilane by distilling the crude product.

Process for the manufacture of monomeric and oligomeric silicic acid esters

An improvement in a process for forming an orthosilicic acid ester or an oligomer thereof by contacting a tetrachlorosilane or higher homolog thereof with a primary alcohol, the improvement which comprises introducing the alcohol directly into a tetrachlorosilane liquid phase without said alcohol touching the gas phase and, after completion of the reaction, removing hydrogen chloride formed during the reaction from the reaction zone.
