2-溴间苯二甲醛缩2-氨基芴双希夫碱缓蚀剂的制备方法及其应用
Abstract:
本发明公开了一种2-溴间苯二甲醛缩2-氨基芴双希夫碱缓蚀剂的制备方法及其应用。本发明通过2-溴间苯二甲醛乙醇溶液与2-氨基芴乙醇溶液混合发生缩合反应得到2-溴间苯二甲醛缩2-氨基芴双希夫碱，然后以水为溶剂，配制成2-溴间苯二甲醛缩2-氨基芴双希夫碱缓蚀剂。2-溴间苯二甲醛缩2-氨基芴双希夫碱含有两个C=N功能团，增强了其在碳钢表面吸附作用，该缓蚀剂能在温度较高，大量存在溶解氧、氯离子、硫酸根离子、微生物的循环冷却水中保持较高缓蚀效果。
Abstract(English):

The invention discloses a preparation method and application of a 2-bromoisophthalaldehyde-2-aminofluorenebischiff base corrosion inhibitor. The method comprises the following steps: mixing a 2-bromoisophthalaldehyde ethanol solution and a 2-aminofluorene ethanol solution, performing a condensation reaction to obtain a 2-bromoisophthalaldehyde-2-aminofluorenebischiff base, and preparing the 2-bromoisophthalaldehyde-2-aminofluorenebischiff base corrosion inhibitor by using water as a solvent. The 2-bromoisophthalaldehyde-2-aminofluorenebischiff base contains two C=N functional groups, the adsorption effect at the surface of carbon steel is enhanced, the corrosion inhibitor can maintain a higher corrosion inhibition effect in circulating cooling water with a large amount of dissolved oxygen,chloride ions, sulfate ions and microorganisms at higher temperature.
