中文摘要: 聚天冬氨酸(PASP)的合成方法很多,合成过程大都比较复杂.为降低原料成本及反应条件的苛刻性,选用马来酸酐和铵盐为原料,采用固相热缩合方法合成了水处理效果较好的PASP.结果表明,固相合成的PASP在分子量为4 000左右时具有较佳的阻垢效果.PASP适用于较高的温度条件.
Abstract:Polyaspartic Acid(PASP) is synthesized with Maleic anhydride and ammonium salt as raw materials through solid phase reaction.The results show that the performance of scale inhibiting to calcium carbonate is at its best when the average molecular weight is about 4000,and this kind of PASP can be well used in high temperature.
