| 目的 研究合成应用于废纸脱墨的表面活性剂。方法 采用脂肪酸和环氧乙烷直接合成有机酸聚氧乙烯嵌段酯 （“醚-酯型” 表面活性剂）， 采用氯乙酸化法合成羧甲基化AEO-9， 用红外光谱对合成产物进行表征， 并对其表面活性、 起泡性、 乳化性、 增溶性、 润湿性等表面性能进行研究， 分析其结构与性能之间的关系。结果 合成的新型有机酸聚氧乙烯嵌段酯表面活性剂各项性能均优于Tween-80； 将 “醚-酯型” 表面活性剂A-107复配应用于浮选法废纸脱墨中， 当改性AEO-9， AEO-9与A-107按质量比3∶2∶1复配时， 脱墨效果最好， 脱墨浆料白度可达到59.4%， 残余油墨量为51.4 mm2/m2。结论 合成的 “醚-酯型”表面活性剂A-107复配应用于浮选法废纸脱墨中具有良好的脱墨效果。 |

| In order to study and develop high-performance surfactant varieties for deinking of wastepaper, we directly synthesize organic acid polyoxyethylene block esters namely "ether and ester type" surfactant using fatty acid and epoxy ethane. And carboxymethylated AEO-9 was synthesized using the chloroacetic acid method. The synthetic products were characterized with infrared spectrometry and the surface properties such as surface activity, foaming, emulsification, solubilization and wettability were studied. The relationship between the structure and the performance was studied. The results showed that the various properties of the novel "ether and ester type" surfactant A-107 synthesized were better than those of Tween-80. The synthesized "ether and ester type" surfactant A-107 was compounded and used in the flotation process of wastepaper deinking. The result showed that when m（modified AEO-9）∶m（AEO-9）∶m（A-107）= 3 ∶2 ∶1, the deinking agent had the best deinking effect, the whiteness of deinked pulp could reach 59.4%, and the residual ink quantity was 51.4 mm2/m2. When compounded and used in the flotation process of wastepaper deinking, the synthesized“ether and ester type” surfactant A-107 had good deinking effect. |
