摘　　要：采用两步法合成了生物降解性好的环保型阻垢剂聚环氧琥珀酸(钠)。利用红外光谱证实了该产物含有醚键;并利用紫外-可见分光光度法分析了体系内副产物酒石酸和未反应的马来酸的含量,并系统地研究了各因素对中间产物环氧琥珀酸(ESA)钠的产率和最终产物聚环氧琥珀酸(PESA)钠阻垢性能的影响。实验结果表明,随体系pH值和反应温度的升高,ESA产率先增大后减小;随引发剂用量的增加,PESA阻垢率也是先增大后减小。A highly efficient, phosphorus-free, nitrogen-free and biodegradable scale inhibitor polyepoxysuccinic acid（PESA） was synthesized and studied. The molecular structure and the existent ether bonds was characterized by IR. The content of tartaric acid and unreaeted maleic acid were detected by spectrophotometer. The effect of some factors on the yield of ESA and Scale inhibition efficiency of PESA was investigated. The result showed that with the increase of pH and reaction temperature, the yield of ESA firstly increased and then dropped. The scale inhibition efficiency firstly rose with the increase of the initiator amount, and then decreased when certain amount was reached.
