摘要
合成了膦基丙烯酸马来酸( 酐) 共聚物阻垢剂 Z P S01 。最佳工艺条件为: A A、 M A 摩尔比75∶25 ,次磷酸盐20 % ,引发剂10 % ,反应时间4 h ,反应温度90 ℃。静态阻垢性能测试结果表明, Z P S01 用作油田污水的阻垢剂,综合性能优于常用阻垢剂 H E D P。
A Phosphono containing crylic acid(AA)/maleic anhydride(MA) copolymer as scale inhibitor ZPS 01 is synthesized by reacting AA, MA with sodium hypophosphite (SHP) at 90℃ in 4 hrs. The molar ratio of AA to MA is 75∶25, the concentration of SHP is 20% and of initiator is 10%. In static scaling experiments ZPS 01 has strong inhibiting ability for carbonate, sulfate and phosphate scale and its performance properties in produced water of Wennan, Zhongyuan, are better than that of commonly used scale inhibitor HEDP.
