英文摘要	以吗啉 ,甲醛和环己胺作原料 ,合成N ,N_二 (4_吗啉甲基 )_环己胺 (BMMCH) ,应用红外光谱和氢核磁共振谱表征其结构 ,并由气相防锈甄别实验和气相防锈能力试验考察其气相防锈性能 ;采用密闭空间挥发减量实验 ,比较其气化挥发能力 .结果表明 ,BMMCH对碳钢具有较好的防锈效果 ;其挥发能力较亚硝酸二环己胺弱 .另通过碳钢在模拟大气腐蚀水中的极化曲线测试 ,发现BMMCH的存在导致碳钢电极的腐蚀电位负移 ,对阴极过程能起抑制作用 ,同时降低了阳极钝化区的电流密度 .电化学阻抗谱研究表明 ,BMMCH对碳钢具有较好成膜稳定性; A Mannich Base derivative (BMMCH), containing two morpholinum moieties and one cyclohexylamnonium moiety, was synthesized through aminomethy1 reaction. Its configuration was verified by IR and 1H_NMR. Its volatile rustproofing effect was appraised by volatile rustproofing sieve test and vapor inhabitability test. The result shows that BMMCH has good protection effect for carbon steel. BMMCH has lower volatility compared with dicyclohexylamnonium nitrite (DICHAN) via closed space volatile weight_loss test. The inhibition mechanism was studied by potentiodynamic polarization electrochemistry technique in ASTM simulated atmospheric water. The corrosion potential of carbon steel electrode shifted to a negative direction when BMMCH was joined in. It had suppressed the cathodic reaction and decreased the current density of anodic passive area.; 作者联系地址：上海电力学院环境工程系,国家电力公司热力设备腐蚀与防护重点实验室,上海电力学院环境工程系,国家电力公司热力设备腐蚀与防护重点实验室,上海电力学院环境工程系,国家电力公司热力设备腐蚀与防护重点实验室上海200090 ,上海200090 ,上海200090; Author's Address: Key Lab for Corrosion and Protection of State Power Corporation, Department of environment engineering, Shanghai University of Electric Power, Shanghai 200090, China
