摘要 通过聚琥珀酰亚胺(PSI)与2-氨基乙醇(AE)在水体系下进行亲核加成反应,合成了一种含羟基的聚天冬氨酸衍生物-羟化聚天冬氨酸(HPAP)。用正交法研究了合成条件对磷酸钙阻垢效果的影响。得到最佳合成工艺条件为:反应温度25℃,反应时间9 h,AE/PSI摩尔比0.4,反应物质量分数18%。HPAP对磷酸钙垢的形成比聚天冬氨酸具有更好的抑制作用。 Poly(aspartic) acid (PASP) derivatives with hydroxyl (HPAP) are synthesized by the nucleophilic addition reaction of polysuccinimide (PSI) with ethanolamine(AE) in water. The effects of reaction conditions on the scale inhibiting performance of Ca3 (PO4)2 are studied by orthogonal experiments. The results show that the optimized conditions are as follows: 9 h of reaction time,25℃ of reaction temperature,0.4 of AE/PSI molecular ratio, 18% of reactants' mass fraction. The HPAP has higher scale-inhibiting capability than that of PASP for Ca3(PO4)2.
