【摘要】 以焦亚硫酸钠、甲醛、乙二胺和二亚乙基三胺为原料，合成了两种新水处理剂ＥＤＴＳ（乙二胺四甲撑磺酸盐）和ＤＴＰＳ（二亚乙基三胺五甲撑磺酸盐）。其元素分析结果与理论值基本一致，产品为纯品，产品的阻垢实验表明，其具有好的阻碳酸钙垢和阻磷酸钙垢的能力。更多还原

【Abstract】 Ethylenediamine-tetramethyl-sulfonate and Diethylenetriamine-pentamethyl-sulfonate, two new water treatment agents, were synthesized from sodium pyrosulfite, formaldehyde, ethylenediamine and diethylenetriamine. The results of their elementary analysis were basically the same as the theoretical values, indicating pure products. The scale inhibition test showed their good calcium carbonate scale and calcium phosophate scale inhibition performance.更多还原
