曼尼希碱的合成及其缓蚀性能评价
Synthesis of Mannich Base and Evaluation on Its Inhibition Performance
摘要
Abstract
Mannich inhibitor was synthesized using cinnamaldehyde,acetophenone and aniline as raw materials,Cyclodextrins as phase transfer catalyst,through condensation of aldehydes and ketones amine generate in the aqueousphase.Under corrosive conditions of refinerycrude oil distillationunit,the optimum polarization extrin amount 0.3% was determined by taking weight loss method and curve scyclod.Effect of the corrosion inhibition of the mannich alkali was investigated using the weight loss method,potentiodynamic polarization and electrochemical impedance spectroscopy .The results showed that the Mannich base was a mixed corrosion inhibitor mainly by restraining the anodic process,and the inhibition rate increased with increasing of Mannich base concentration.When the amount of inhibitor concentration was 0.2%,the inhibition rate reached 94.37%,and Mannich base can effectively inhibit corrosion of 20 # steel in the HCl-H 2 S-H 2 O system.关键词
