新型水溶性防锈剂的合成与应用

Synthesis and Application of New Water-base Antirust

以噻二唑为原料合成了取代噻二唑酸,再由取代噻二唑酸与二乙醇胺发生酰化反应合成新型的噻二唑型防锈剂,并考察温度对加成反应的影响。采用防锈试验和静态失重法等测得所合成的防锈剂在腐蚀介质中的缓释效率,试验结果表明,该类防锈剂缓释效果明显,产率高,工艺简单,具有良好的防锈性能。

Sub-thiadiazole acids were synthesized using thiadiazole as raw material,which further reacted with diethanolamine to prepare the novel thiadiazole-based antirusts.The influence of temperature on the addition reaction was studied and the release efficiency of the antirust in the corrosive media was measured by rust test and static weight loss method.The experimental results show that the effects of such antirusts are of high yield,simple process and better antirust performance.
