以苯并三氮唑(BTA)和溴代正丁烷为原料,采用一步法合成了N-丁基苯并三氮唑(N-BBTA),研究了BTA、N-BBTA以及N-BBTA与BTA的复配体系对铜在3％(质量分数)NaC1溶液中的缓蚀行为.结果表明,单一N-BBTA和BTA对铜均具有一定的缓蚀能力.当N-BBTA、BTA浓度为10 mmol/L时,缓蚀率分...
N-butyl benzotriazole(N-BBTA) was synthesized with benzotriazole(BTA) and n-butyl bromide as raw materials by a one-step process.The corrosion inhibition of BTA,N-BBTA and composite inhibitor of BTA with N-BBTA on copper in 3wt% NaCl solution was studied.The results proved that both single BTA and N-BBTA present a corrosion inhibition effect.The corrosion inhibition efficiency of BTA and N-BBTA is 60.61% and 72.05%,respectively,when their concentrations are 10 mmol/L,but it is up to 93.46% when BTA and N-BBTA is mixed at a concentration ratio of 8 mmol/L to 2 mmol/L,showing a good synergistic effect.Air accelerating corrosion test showed that the atmosphere corrosion inhibition of copper is remarkably improved in the composite system.
