Synthesis method of Methyl trioctyl ammonium chloride CAS 5137-55-3
1. Autoclave method
396 g (1 mole) of N235 and 300 ml of ethanol were mixed in the autoclave, and the autoclave was used for ice-acetone cooling. Then pour 2 moles of methyl chloride (pre-frozen and liquefied, collected in an Erlenmeyer flask), immediately close the autoclave, stir and heat to 100, react under a pressure of <10 kg/cm2 for 4 to 5 hours, and cool to room temperature , Release residual methyl chloride. Then the ethanol is removed by vacuum distillation to obtain a brown product weighing about 430 grams (95-100%).
2. Atmospheric pressure method
100 ml (52 g, 0.2 mol) of N235 and isooctanol with a volume ratio of 1.5:1 to N236 were placed in a tubular reactor, and methyl chloride was introduced at a flow rate of 150 ml/min for about 20 minutes. Then heated to 130°C. Methyl chloride was introduced at the flow rate of tiny bubbles, and reacted for 5 to 7 hours. After cooling, the reactant is transferred to a liquid film evaporator, and the product is obtained by vacuum distillation at 120-130°C/3-5mm to evaporate the solvent. The conversion rate is 60-70%.
