【摘要】：以丙烯酰氯、对氨基苯甲酸为原料,通过N酰化反应及中和反应合成单体——对丙烯酰胺苯甲酸钠(a),并以过硫酸铵/亚硫酸氢钠为复合引发剂,以自制的对丙烯酰胺苯甲酸钠和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体通过水溶液自由基共聚法合成了二元聚合物(b)。利用延长原油模拟的原油乳液对聚合物的破乳性能进行了考察,同时研究了聚合物的絮凝性能和对含油废水的除油效果。结果表明,在破乳温度70℃、处理时间2 h的条件下,当聚合物(b)投加量为110 mg/L时,脱水率达92.04%;在室温下,当自制聚合物投加量为12 mg/L时,硅藻土悬浮液上层清液的絮凝时间为9 s,透光率为98.6%;在聚合物投加量为30 mg/L、温度为50℃、处理时间为7 h的条件下,对含油废水的除油率达94.5%;与市售破乳剂BQ-05、SP-169及市售絮凝剂PAM、PDMC相比,自制聚合物具有更好的絮凝破乳性能。
[Abstract]:Using acryloyl chloride and p-aminobenzoic acid as raw materials, the monomer -p-acrylamide sodium benzoate was synthesized by N-acylation reaction and neutralization reaction. Ammonium persulfate / sodium bisulfite was used as the complex initiator. In this paper, a binary polymer (BX) was synthesized from sodium p-acrylamide benzoate and methacryloxy ethyl trimethylammonium chloride (DMCC) by free radical copolymerization in aqueous solution. The polymer was prepared by using the crude oil emulsion simulated by extended crude oil. The demulsification performance was investigated. At the same time, the flocculation property of polymer and the deoiling effect of oil containing wastewater were studied. The results showed that the dehydration rate reached 92.04and the dehydration rate reached 92.04g at room temperature at 70 鈩，
