摘要
为了研究咪唑啉类化合物在以磷酸为介质的酸化液中对金属的缓蚀性能,使用不同的羧酸、多胺合成了多种咪唑啉和咪唑啉季铵盐,考察了这些咪唑啉类化合物及其复配物在质量分数为10%的磷酸中对低碳钢(N80钢)的缓蚀性能。
To study the corrosion inhibition performances of imidazolines for the metals in acidifying liquid of phosphoric acid, different carboxylic acids and polyamine salts were used to synthesize different imidazolines and quaternary amine salts of imidazoline. The corrosion inhibition performance of these imidazolines compounds and their complexes for the low carbon steel （ NSO steel） in the liquid of 10% of phosphoric acid are investigated.
