摘要
以马来酸酐、尿素为原料合成聚琥珀酰亚胺,再将聚琥珀酰亚胺与改性剂反应生成改性聚天冬氨酸。通过合成条件实验,确定了合成改性聚天冬氨酸最佳反应物摩尔比、缩聚反应温度和改性剂。并通过静态阻垢法和旋转挂片法测定了改性聚天冬氨酸的阻垢率和缓蚀率。改性聚天冬氨酸的的阻垢率和缓蚀率分别为95.42%和%95.65。与未改性的聚天冬氨酸相比,阻垢率和缓蚀率分别提高了9%和5.64%.
Polysuccinimide was synthetized from maleic anhydride which was determined by the experiment. In order to choose the experiment was also applied to confirm them. By static ex of scale inhibitor and corrosion inhibitor was determined. and urea in the optimal temperature best ratio of mole and modifier, the periment Because and rotating hanging plate, the rate of the modification of modifier, the rate of scale inhibitor and corrosion inhibitor was more 9% and 5.64% than the unmodified polyas- partic acid respectively.
