High quality of Pharmaceutical grade Didecyldimethylammonium chloride WholesalerFast Delivery 7173-51-5 DDDA with high purity
The production method is mainly divided into two routes.
①In the presence of potassium iodide, chlorodecane reacts with methylamine to prepare didecylmethyl tertiary amine, and then the didecylmethyl tertiary amine is placed under pressure and heated in a medium of water and isopropanol It reacts with methyl chloride under pressure to obtain the product of didecyldimethylammonium chloride.
The reaction formula is as follows:
②In the presence of a catalyst, the amination reaction is carried out from the mixed gas of n-decyl alcohol, hydrogen and methylamine, and didecylmethyl tertiary amine is prepared first. Then add didecylmethyl tertiary amine, a small amount of sodium carbonate and an appropriate amount of isopropanol into the autoclave. After replacing the air with nitrogen, the temperature is raised to 80～90℃, methyl chloride is introduced, and the pressure is 0.3～0.5MPa, and the reaction is 3～ The product of didecyl dimethyl ammonium chloride can be obtained in 4 hours.
The reaction formula is as follows:
