摘要
用壬基酚聚氧乙烯醚(TX-10)与氯丙烯合成了一种含醚单体(TXA),再用丙烯酰胺(AM)、丙烯酸(AA)与TXA采用自由基聚合法合成了疏水缔合聚丙烯酰胺(TXPAM)。确定了TXPAM的最佳合成条件为:n(AM)∶n(AA)∶n(TXA)=100∶20∶0.4,总单体含量为20%,体系pH为6.5,反应温度为40℃,引发剂加量0.2%,反应时间为5 h。采用红外光谱法和核磁共振氢谱对TXPAM的结构进行了表征,采用元素分析法对TXPAM的C,H,O,N元素的含量进行了测定,3种表征方法证实了TXPAM符合预期设计。考察了TXPAM的耐温抗盐抗剪切性能和驱油性能,与常规PAM相比,耐温达到80℃,抗盐8000 mg/L,抗剪切10000 s^(-1),提高采收率16.03%,有进一步研究的意义。
An ether containing monomer(TXA)was synthesized with nonylphenol ethoxylate(TX-10)and chloropropene(AA).Then,the hydrophobically associating polyacrylamide(TXPAM)was synthesized by free radical polymerization of acrylamide(AM),acrylic acid(AA)and TXA.The optimum synthesis conditions of TXPAM were studied,n(AM)∶n(AA)∶n(TXA)=100∶20∶0.4,total monomer content of 20%,pH of 6.5,reaction temperature of 40℃,initiator dosage of 0.2%,reaction time of 5 h.The structure of TXPAM was characterized by IR and 1H-NMR.The contents of C,H,O and N in TXPAM were determined by elemental analysis.The three characterization methods confirm that TXPAM meets the expected design.Compared with conventional PAM,TXPAM has a temperature resistance of 80℃,salt resistance of 8000 mg/L,shear resistance of 10000 s^(-1)and enhanced oil recovery of 16.03%,which is significant for further study.
