introduction | N,N, N-trimethyl-1-decatane ammonium bromide, also known as tetramethyltrimethylammonium bromide, is a quaternary ammonium salt and a cationic surfactant. High purity quaternary ammonium salt is an excellent phase transfer catalyst and plays a key role in organic synthesis. |
application | N,N, N-trimethyl-1-decatane ammonium bromide can be used as a cationic surfactant. High purity quaternary ammonium salt is an excellent phase transfer catalyst and plays a key role in organic synthesis. |
preparation | weigh 400kg of decyldimethyl tertiary amine and place it in a 1000-liter enamel reaction kettle, pump 263kg of hydrobromic acid at a flow rate of 160kg/h, 125kg of methanol and 0.4kg of ionic liquid 1-ethyl-3-methylimidazolium hydrobromide mixture, stir the reaction at 50 ℃, the reaction time is 3 hours, atmospheric reaction under nitrogen atmosphere. After the reaction product is vacuum dried (the drying temperature is controlled at 80 ℃), it is added into a 1000L high-pressure reactor. After the reactor is blown three times with nitrogen, 168kg of dimethyl carbonate and 80kg of methanol mixture are pumped into a closed reaction at a flow rate of 20kg/hour. The reaction temperature is 175 ℃, the reaction pressure is 1.7MPa, and the reaction is stirred for 12 hours. The reaction product was dried in vacuum (the drying temperature was controlled at 80 ℃) to obtain about 553kg of N,N,N-trimethyl-1-decatane ammonium bromide with a yield of 99.1% and a purity of 99.1%. |
use | used as surfactant, suitable for shampoo, rubber, coating and other industries cationic surfactant, can be used as catalyst, emulsifier, bactericide, disinfectant, antistatic agent and so on. Applied to ion pair chromatography, anionic detergent, deodorant, catalyst, emulsifier, disinfectant, germicidal base, antistatic agent and experimental use. |
