以壬二酸为原料，采用臭氧联合催化剂催化氧化方法合成油酸，复配制备CW-1捕收剂。考察合成时间与氧化剂种类对合成效果的影响，结果显示，最佳反应时间为120 min、氧化剂为双氧水。分别采用开路和闭路方法对比CW-1捕收剂与KS-2捕收剂选别选矿试验，表明CW-1捕收剂具有较好的低温使用效能，同时利用红外光谱分析CW-1捕收剂浮选机理。%After the oleic acid was synthesized by azelaic acid as raw material though the catalytic oxidation of ozone combined with catalysis, CW-1 collector was prepared by means of the oleic acid mixed with some chemicals. The influences of synthesis span and oxidant on the conversion rate is investigated. The results show that the synthesis span and oxidant of 120 min and H2O2 are optimal. The open and closed circuit experi-ment are made to compare the flotation ability of CW-1 collector and KS-2 collector, which is demonstrated that the CW-1 collector reveals the flotation ability at lower temperature. The infrared spectrum analysis was used to investigate the floating mechanism of the CW-1 collector.
