膦酰基羧酸共调聚物的合成及性能
摘要:
以丙烯酸(AA),2-丙烯酰胺基-2-甲基-丙磺酸(AMPS),次亚磷酸钠及过硫酸钠等为原料,合成了多功能水处理剂膦酰基羧酸共调聚物,以合成产品对CaCO3的抑制能力为考核指标,研究了反应条件对碳酸钙垢、磷酸钙垢、锌盐沉积的抑制能力及对氧化铁的分散能力.在原料配比m(AA): m(AMPS)=3:1,m(NaH2PO2): m(Na2S2O8): m(AA+AMPS)=15:2.5:100,反应温度为110℃,反应时间为4 h的反应条件下,所合成的产品具有优良的阻垢分散性能,优于羟基乙叉二膦酸(HEDP)和水解聚马来酸酐(HPMA).

Synthesis of Phosphono Carboxylic Acid Cotelomer and Its Property
Abstract:
A phosphono carboxylic acid cotelomer(POCA) was prepared from acrylic acid(AA), 2-acrylamido-2-methylpropane sulfonic acid(AMPS), NaH2PO2 and Na2S2O8. The optimum synthetic conditions were: m(AA)/m(AMPS)=3:1, concentration of NaH2PO2=15%,concentration of Na2S2O8=2.5%, temperature 110℃, time 4 hours. The product showed a better scale inhibiting and dispersing property than HEDP(hydroxyethylidene bisphosphonic acid) and HPMA(hydrolytic polymaleic anhydride).
