Fire is for high-grade copper smelting refining , wet copper smelting can be used to extract low-grade , but how to extract copper from the acid process has been difficult , organic extractant can be a good solution to this problem . This thesis is the synthesis started from LIX841 change materials adding ways to get practical organic synthesis routes. We -nonylphenol , acetic anhydride , hydroxylamine hydrochloride as the basic raw material , the nonylphenol at 80 ℃ , using anhydrous aluminum chloride as a catalyst in the ratio of 1.3:1 to nonylphenol material , time-consuming 90min, acyl after that pair of nonylphenol acetate. Raising the temperature to 120 ℃, the rearrangement reaction time is about 120min, obtain one of nonylphenol acid (HNA), the highest yield was 64.2% . After purification , using hydroxylamine hydrochloride the HNA oxime , the temperature at 85 ℃, material ratio of 1.2:1 , an acidity of pH = 7.5, which lasted 150min , the final product of nonyl acetophenone oxime (HNAO), yield up to 65.4% . Respectively, with HNAO HNA synthesis intermediates were characterized by infrared spectroscopy and NMR spectra see Appendix around extractant LIX841 that HNAO, extraction kinetics, thermodynamics extraction , stripping kinetics experiment , stripping agents and other conditions acidity test. Finally established by comparison (O / A) = 0.10, pH = 2.8, temperature 25 ℃, extraction time 60min , the extraction efficiency of up to 92.5% ; stripping conditions pH = 3, anti- extraction temperature is 25 ℃, anti extraction time 45min , the stripping rate up 94.5 percent .
