OCTADECYL DIISOBUTYL (DIMETHYL AMINO) SILANE - Introduction

n-Octadecyldiisobutyl (diethylamino) silane is also known as 18-alkyne diisobutyl dimethylaminosilane, the chemical formula is C30H60N2Si. The following is an introduction to its nature, use, preparation and safety information:

Nature:
n-Octadecyldiisobutyl(dimethylamino)silane is a colorless to light yellow liquid. It has a low melting point and boiling point, moderate solubility. It has good heat resistance, weather resistance and chemical stability.

Use:
n-Octadecyldiisobutyl(dimethylamino)silane is commonly used as a surfactant and adjuvant. Because it is both hydrophobic and lipophilic, it can increase the wettability and dispersibility of water-based coatings, inks and adhesives. It can improve the adhesion and anti-stickiness of the coating, and improve the moisture, water and weather resistance. In addition, it can also be used as a cutting fluid, abrasive and anti-sticking agent for rubber and plastics.

Method:
The preparation of n-Octadecyldiisobutyl(dimethylamino)silane is usually obtained by reacting acetylene diisobutyl disilanol with N-octadecanoic anhydride. This reaction is usually carried out in a reaction vessel charged with a solvent such as dimethylformamide and an acid catalyst such as trifluoromethanesulfonic acid at an appropriate temperature. The product is then obtained by distillation and purification steps.

Safety Information:
n-Octadecyldiisobutyl(dimethylamino)silane use should pay attention to safety precautions. It can be irritating and corrosive to the eyes and skin. Wear appropriate personal protective equipment such as gloves, goggles and protective clothing during operation. Ensure that the operation is carried out in a well-ventilated place while avoiding inhalation of gas, steam or spray. Please refer to the product specific safety data sheet and follow the relevant safety procedures before use.
