OCTADECYLDIMETHYL (DIMETHYLAMINO) SILANE - Introduction
n-Octadecyldimethyl(dimethylamino)silane, also known as n-Octadecyldimethyl(dimethylamino)silane, its chemical structure is (CH3)2N(CH3)SiC18H37. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: A colorless to slightly yellow liquid.
- pH: It is alkaline in water.
-Solubility: Soluble in common organic solvents such as alcohol, ether, ketone and petroleum ether.
Use:
-Surfactant: n-Octadecyldimethyl(dimethylamino)silane is commonly used as a surfactant to increase the water resistance and adhesion resistance of coatings, inks and adhesives.
-Surface modifier: It can be used to improve the wettability and adhesion of polymer surfaces, and is commonly used in the treatment of fibers, fillers and pigments.
-Electronic materials: Because it can improve the dielectric constant and antistatic properties, it can also be used in electronic materials.
Preparation Method:
The preparation of n-Octadecyldimethyl(dimethylamino)silane is usually achieved through the hydrosilylation reaction and nucleophilic substitution reaction of silane. A specific procedure involves reacting "n-Octadecyldimethylchlorosilane"(n-octadecyldichlorosilane) and "dimethylamine" (dimethylamine) under appropriate conditions.
Safety Information:
- n-Octadecyldimethyl(dimethylamino)silane is a hazardous chemical, please follow the relevant safety procedures for experimental operation.
-Avoid contact with skin and eyes and wear protective gloves, goggles and protective clothing if necessary.
-Store away from fire and oxidizing agents, in sealed containers, away from acids, alkalis and other organic substances.
-Prevent inhalation, ingestion or swallowing of this compound during use.
-In the event of an accident, take appropriate emergency measures in a timely manner and seek medical advice.
