一种固体型咪唑啉缓蚀剂的合成与性能研究

Study on Preparation and Corrosion Inhibitive of a Solid Imidazoline Derivative

利用硬脂酸与多乙烯多胺反应得到硬脂酸咪唑啉,而后进行季铵化制备了一种固体型缓蚀剂,考察了季铵化试剂、季铵化温度、季铵化试剂用量、季铵化时间对产品缓蚀效果的影响,筛选出最佳季铵化试剂与季铵化条件。该固体型缓蚀剂用量为100 mg/L时,缓蚀率可达到80%以上。

Stearic acid imidazoline was synthesized by the reaction of stearic acid and polyethylene polyamine and it was then quaternized by different agents. With the corrosion inhibition performance screening, the preparation conditions of this kind of solid imidazoline corrosion inhibitor were optimized. Under the condensation of 100 mg/L, the corrosion mitigation rate of the corrosion inhibitor was more than 80 %.
