Embodiment 1
[0045] In a 500ml three-necked flask equipped with a reflux condenser, a stirrer, and a thermometer, add 0.4mol of 2-(chloromethyl)pyridine hydrochloride, 0.2mol of p-nonylphenol, 180ml of methanol, and 2.5mol / L of sodium carbonate solution 200ml. Heat in a water bath, start stirring, and react under normal pressure. When the temperature reaches the set temperature, start timing. The reaction was carried out at 70°C for 8 hours. After the reaction, after solid-liquid separation, remove methanol and water by vacuum distillation, dissolve with 400ml tetrachloroethane, wash with acid, alkali, and water, then remove tetrachloroethane by vacuum distillation to obtain HX extractant. The yield of the HX extractant is: 60.3%.
Embodiment 2
[0047] In a 500ml three-necked flask equipped with a reflux condenser, a stirrer, and a thermometer, add 0.2mol of p-nonylphenol, 80ml of methanol, and 100ml of a 2.5mol / L sodium carbonate solution. Heat in a water bath, start stirring, and react under normal pressure. When the temperature reaches the set temperature, start timing. After reacting at 70° C. for 30 minutes, 100 ml of a mixed solution containing 0.4 mol of 2-(chloromethyl) pyridine hydrochloride in methanol and 100 ml of 2.5 mol / L of sodium carbonate solution was added dropwise. The reaction was continued at 70°C for 8 hours. After the reaction, after solid-liquid separation, remove methanol and water by vacuum distillation, dissolve with 400ml tetrachloroethane, wash with acid, alkali, and water, then remove tetrachloroethane by vacuum distillation to obtain HX extractant. The yield of the HX extractant is: 88.5%.
Embodiment 3
[0049] In a 1000ml three-neck flask equipped with a reflux condenser, a stirrer, and a thermometer, add 0.4mol of p-nonylphenol, 160ml of methanol, and 200ml of a 2.5mol / L sodium carbonate solution. Heat in a water bath, start stirring, and react under normal pressure. When the temperature reaches the set temperature, start timing. After reacting at 70° C. for 30 minutes, 200 ml of a mixed solution containing 0.8 mol of 2-(chloromethyl) pyridine hydrochloride in methanol and 200 ml of 2.5 mol / L of sodium carbonate solution was added dropwise. The reaction was continued at 70°C for 8 hours. After the reaction, after solid-liquid separation, remove methanol and water by vacuum distillation, dissolve with 400ml tetrachloroethane, wash with acid, alkali, and water, then remove tetrachloroethane by vacuum distillation to obtain HX extractant. The yield of the HX extractant is: 84.2%.
