| Use | Methyl trioctyl ammonium chloride, also known as trioctyl methyl ammonium chloride, is a halogenated quaternary ammonium salt. Quaternary ammonium salt is a kind of cationic surfactant, among which halogenated quaternary ammonium salt (R1R2R3R4N X-) series compounds are widely used in daily chemical industry, textile, printing and dyeing, mining, asphalt, construction, plastic processing, petroleum exploitation, petrochemical industry and other fields, playing an important role. C8 and C10 chain mixture, C8 occupies the main body. Used as metal extractant and phase transfer catalyst. Phase transfer reagent |
| preparation | weigh 1000g of trioctylamine and place it in a beaker, add concentrated hydrochloric acid (HCl adds a total of about 103g) drop by drop, stir by magnetic force, evaporate with a constant temperature water bath to remove about 80% of the water after the neutralization reaction, and then dry the product trioctylammonium chloride in vacuum. Weights 1000g of trioctylammonium chloride and 235g of dimethyl carbonate respectively, and add them to a 10L reaction kettle in turn, after purging with nitrogen to drive away the air in the kettle, the reaction is carried out in a closed manner. The reaction temperature is 170 ℃, and stirring is started after the reaction temperature reaches 170 ℃. The reaction time is 8 hours. After the reaction is over, about 1026g of methyl trioctylammonium chloride was prepared. |
| production method | 1.396g (1 mol) N235 and 300 ml ethanol are mixed in an autoclave by autoclave method, and the kettle body is used for ice-acetone cooling. Then pour 2 moles of methyl chloride (pre-frozen and liquefied, collected in a conical flask), immediately close the autoclave, stir and heat until 100 react at a pressure of <10kg/cm2 for 4-5 hours, then cool to room temperature and release residual methyl chloride. Then vacuum distillation removes ethanol to obtain brown product, weighing about 430 grams (95-100%). 2. By atmospheric pressure, 100 ml of 52g, 0.2 mol) N235 and isooctanol with a volume ratio of 1.5:1 to N236 are placed in a tubular reactor, and methyl chloride is introduced at a flow rate of 150 ml/min for about 20 minutes. Then heat to 130 ℃. Methyl chloride was introduced at the flow rate of tiny bubbles and reacted for 5-7 hours. Cooling, the reactants are transferred to the liquid film evaporator, and the solvent is evaporated by vacuum distillation at 120-130 ℃/3-5mm to obtain the product. The conversion rate is 60-70%. |
