一种新型四元聚合缓蚀阻垢剂的合成和性能评价

以马来酸酐(MA)、丙烯酸(AA)、烯丙基磺酸钠(SAS)和丙烯酸羟丙酯(HPA)为单体,水为溶剂,过氧化氢/次磷酸钠为引发剂,合成了四元聚合缓蚀阻垢剂PMASH.通过大量试验确定了最佳合成条件.实验结果表明:PMASH质量浓度为5 mg/L时,对碳酸钙垢和磷酸钙垢阻垢率分别达87.6%和85.4%,缓蚀率为83.9%.红外光谱检测表明PMASH分子结构含羧基、膦酰基和磺酸基等官能团.

Synthesis and performance of a new type of quadripolymer scale and corrosion inhibitor

With water as solvent and sodium hypophosphite/hydrogen peroxide as initiator,a novel quadripolymer scale and corrosion inhibitor,denoted as PMASH,has been systhesized with maleic anhydride(MA),acrylic acid(AA),sodium acrylsulfonate(SAS) and hydroxyl propyl acrylic(HPA).Moreover,its preparation procedures are optimized.When 5 mg/L of this quadripolymer is used,the scale inhibition rates of CaCO3 and Ca3(PO4)2 are 87.6% and 85.4% respectively and corrosion inhibition rate is 83.9%.The infrared spectrum indic...
