Aqueous Synthesis of N, N-dihydroxyethyl laurylamine N,N-二羟乙基十二烷基胺的水相合成研究
A new type of anionic trimeric surfactant containing easily degradable carboxylic groups and hydrophilic hydroxyl groups in its molecular structure was synthesized based on harmless and non-toxic propanetriol glycidyl ether, laurylamine and sodium chloroacetate. 采用丙三醇缩水甘油醚、十二胺和氯乙酸钠为原料合成了一种新型丙三醇型三联阴离子表面活性剂,该分子结构中含有易降解的羧基和亲水基团羟基,且所用原料均无毒无害。
The results of XPS and AES analyses showed that on tinplate surface an anticorrosive coordination compound film of laurylamine was formed, and N atoms in laurylamine molecule were coordinated with Sn ( II). XPS和AES分析结果表明,月桂胺中的氮与锡表面发生配位作用并在锡表面形成耐蚀性保护膜。
The effect of reaction time on degree of polymerization and degree of branching ( DB) was studied by using laurylamine as the reaction stopper. 利用封端剂十二胺使反应终止,研究了不同反应时间对产物支化度及聚合度的影响。
Organic small molecule inhibitors were targeted and screened in laurylamine collector system. Oxalic acid, the high-selective inhibitor for the separation of feldspar and quartz, was found. 主要针对有机小分子抑制剂进行了筛选,找到了十二胺体系下,长石和石英分选的高效选择性抑制剂&草酸。
