摘要
以水杨酰肼、甲醛、苯乙酮为原料,合成了一种Mannich碱,结合对N-80钢片在盐酸中的缓蚀效果对其合成条件进行了优化,并对其与无机增效剂的协同作用进行了研究。经复配得到了未见报道的不含炔醇的复合酸化缓蚀剂。实验结果表明,该Mannich碱复配物在盐酸溶液中分散性好,具有优良的缓蚀性能。
A kind of Mannich alkali was synthesized with henzoyl hydrazine, methyl aldelyde and phenethyl ketone. According to the result of the corrosion evaluation to N-80 steel piece in hydrochloric acid, the reaction condition was optimized and the synergistic effect between the mannich alkali and inorganic synergist was studied. A new mixed corrosion inhibitor without alkynols was obtained. The new inhibitor had good dispersion in hydrochloric acid and effective inhibiting performance.
