2,4,6-三（4,-羧基-1,-羧丙氨基）-1,3,5-三嗪

Synthesis of 2,4,6-tri[(4,- carboxyl-1,-carboxypropyl)amino]-1,3,5-trizine and Its Performance on Scale Inhibition

摘要:

用三聚氯氰和谷氨酸为原料，合成2,4,6-三（4,-羧基-1,-羧丙氨基）-1,3,5-三嗪（TGAT）。讨论了反应物配比、反应时间、反应温度对产率的影响。FTIR及1HNMR表征了衍生物的结构。通过对产物进行阻垢实验发现，该类型阻垢剂对碳酸钙有良好的阻垢效果。通过扫描电镜考察了阻垢剂碳酸钙垢晶型的变化，结果表明TGAT可使碳酸钙垢晶型完全扭曲，形成球霰石晶体，从而达到阻垢目的。

Abstract:

A kind of cyanuric chloride derivatives with sale inhibition effect was prepared by cyanuric chloride and glutamic acid. The effects of the reactant ratio，the reaction time , the temperature used on the reaction were discussed. The structure was characterized by infrared spectrum. The results of scale inhibition experiment of product which were used as scale inhibitors show that the type of scale inhibitor has good scale inhibition on calcium carbonate. the study on the change of crystal form of the scale inhibitor calcium carbonate was carried out by means of scanning electron microscope analysis, the results thereof show that the crystal form of calcium carbonate can be completely distorted to form a vaterite crystal to realize the purpose of scale inhibition through 2,4,6-tri[(4,- carboxyl-1,-carboxypropyl)amino]-1,3,5-trizine.
