聚环氧琥珀酸的合成及其阻垢性能研究

研究了各种合成条件对聚环氧琥珀酸钠阻垢性能的影响,得到了合成聚环氧琥珀酸钠的最佳工艺条件为:环氧琥珀酸钠与氢氧化钙的量比为1:0.016,反应时间3h,反应温度95℃。通过对产物的红外光谱分析,证明产物与聚环氧琥珀酸钠有相同的基团。通过对不同投加量的PESA阻垢性能测试表明:在投加量分别为10和80mg/L时,对硫酸钡垢、硫酸锶垢的阻垢率可达100%。并初步探讨了其阻垢机理。

Synthesis of polyepoxysuccinic acid and its scale inhibition performance

Effects of different synthesis conditions on the scale inhibition performance of polyepoxysuccinic acid were studied;meanwhile,the optimal process condition for the synthesis of polyepoxysuccinic acid was found,which was: the mass ratio between epoxysuccinic acid and calcium hydroxide was 1 : 0.016,the reaction time was 3 h,the reaction temperature was 95 ℃.Through the analysis of the product using infrared spectroscopy,the said product was proved to have the same groups with sodium polyepoxysuccinic acid.When the dosage was different,the scale inhibition performance of polyepoxysuccinic acid was tested,the results show that: when the dosage were 10 and 80 mg/L,the removal rate of barium sulfate scale and Strontium sulfate scale reached 100%.The mechanism of its scale inhibition was also primarily discussed.
