Octyldimethylmethoxysilane - Introduction

Nature:
-Appearance: colorless transparent liquid
-Boiling point: about 230 degrees Celsius
-Density: about 0.82g/cm³
-Melting point: about -80 degrees Celsius
-Solubility: Soluble in organic solvents, slightly soluble in water
-Stability: stable, but avoid contact with strong oxidants

Use:
methoxydimethyloctylsilane is a commonly used silicone monomer, widely used in various fields:
-Surface treatment agent: It can be used as an additive for surface coatings and coatings, which can improve the weather resistance and adhesion of the coating.
-Electronic materials: can be used to prepare flexible electronic devices, photoelectric materials and organic solar cells.
-Functional lubricant: used in lubricating oil and grease to improve the lubricating performance of the product.

Method:
The preparation of methoxydimethyloctylsilane is generally obtained by a hydrogen silicon chemical reaction. A specific production method may be that the target product is obtained by reacting 1-octene with methylmagnesium hydride, and then reacting with methanol.

Safety Information:
