一种氨烷基膦酸型水处理剂的合成及缓蚀阻垢性能的研究

Synthesis of[(dimethylamino)methylene]bisphosphonic acid and researcnes on its corrosion and scale inhibition performances

介绍了一种氨烷基膦酸型水处理剂二甲基氨基甲叉二膦酸(DMAMDP)的合成方法,并进行了缓蚀阻垢性能的研究。结果表明,DMAMDP在阻碳酸钙、硫酸钙、磷酸钙和稳定锌等方面,以及缓蚀性能均优于常用有机膦酸水处理剂HEDP和ATMP。

Abstract： Ten new disubstituted triazinyl carbantkyred derivatives were synthesized by the reaction o（ N-substitued trichloacetanlidel and 4,6-Dimethoxide-2-Ttiazinylurea undermicrowaveave irradiation, their structures were confirmed by elemental analy sis, IR, and ^1H NMR. The preliminary biological activity test of new compound was determined by hydropionics experiment. The results indicate that some of them show an obvious inhibitory activity for plant growth. At concentration of 1. 0 × 10^-3, the compound 3a-3e give inhibitory activity of 100% for cucumber, 98 % for wheat. At concentration of1. 0 × 10^-4 , the compound gives inhibitory activity of 83. 15-94. 54%for cucumber, 85. 13-81.97%for wheat.
