【摘要】 以丙烯酸和十八醇为原料合成丙烯酸十八酯。探讨了反应时间、反应温度、催化剂用量对酯化率的影响。用红外光谱仪、核磁共振仪、气相色谱仪、质谱仪等对产物的结构进行了表征。根据所设计的因素和水平,采用正交试验方法统计,寻找了该合成反应的最佳合成工艺条件。将产品作为疏水单体与丙烯酰胺共聚,采用胶束聚合法,以十二烷基磺酸钠为乳化剂、过氧化苯甲酰为引发剂,在氮气保护下反应,得到疏水改性聚丙烯酰胺。并研究聚合反应的影响因素:物料配比、表面活性剂、引发剂、反应温度和时间、旋转速度的影响,用旋转粘度计测定聚合物的表观粘度,以膨润土溶液为废水水样,考察聚合物的絮凝性能及相关应用。

【Abstract】 Octadecyl acrylate was synthesized with acrylic acid and octadecanol as raw materials. Theinfluences of reaction time, reaction temperature, amount of catalyst on esterification wereinvestigated by orthogonal design. The IR spectra and ~1H-NMR spectra characteristics ofthe product were in good agreement with that of literatures. Hydrophobic modifiedpolyacrylamide was synthesized by the copolymerization of octadecyl acrylate(ashydrophobic monomer) and acrylamide. The reaction was proceeded under nitrogen gas,using sodium dodecanesulphonate as emulsifier, Benzoyl Peroxide(BPO) as initiator.Apparent viscosity was determined by rotational viscometers. Porcelain clay solution wasused as waste water sample to determine the flocculation property of the hydrophobicmodified polyacrylamide.
