The uses of octadecyldimethyltertiary amine are as follows:
Octadecyldimethyltertiary amine is an important organic synthesis intermediate for quaternary ammonium salt-type cationic surfactants.
Can react with ethylene oxide, dimethyl sulfate, diethyl sulfate, methyl chloride, benzyl chloride, etc. to generate different quaternary ammonium salt cations , can be used in products such as fabric softening, antistatic agents, and improving hair combability.
The reaction of octadecyldimethyltertiary amine with ethylene oxide and nitric acid can produce octadecyldimethylhydroxyethyl quaternary amine. Ammonium nitrate, antistatic agent SN.
It can also be used to produce insect repellent.
