Trisiloxane, 1,1,1,5,5,5-hexamethyl-3-octyl-3-[(trimethylsilyl)oxy]- - Introduction
Nature:
N-Octyltris(trimethylsilyloxy)silane is a colorless liquid with a light odor. It is stable at room temperature, but will decompose at high temperatures to produce toxic silicon oxide gas. This compound is insoluble in water, but soluble in organic solvents such as alcohols and aromatic hydrocarbons.
Use:
OTS has super hydrophobic properties, so it is widely used in surface coating, textile waterproof, ink, leather treatment agent and other fields. It can form a layer of tiny, inorganic organic hybrid silicone film, thereby changing the hydrophilicity of the substrate surface, to achieve the effect of water and oil resistance.
Method:
N-Octyltris(trimethylsilyloxy)silane can be prepared by Silylation reaction. A common synthetic method is the reaction of N-octyltrichlorosilane with trimethylchlorosilane and hydrolysis under alkaline conditions.
Safety Information:
N-Octyltris(trimethylsilyloxy)silane has low toxicity under normal use conditions, but the following safety precautions still need to be paid attention:
-On contact with skin or inhalation, rinse immediately with plenty of water and seek medical assistance.
-Avoid reacting with strong oxidants to avoid harmful gases.
-Good ventilation should be provided during use to avoid inhalation of vapors.
-Store in a cool, dry place, away from fire and high temperature.
Generally speaking, N-Octyltris(trimethylsilyloxy)silane is a compound with wide application, but it is necessary to pay attention to safe operation during use. Before use, it is best to read the relevant safety manual or consult a professional.
