| Abstract: | To further enhance the comprehensive experimental skills of undergraduate students and promote the concept of green chemistry education, we have developed a comprehensive undergraduate experiment focusing on acylhydrazide corrosion inhibitors for oilfield pipeline corrosion. Initially, a thorough analysis of corrosion factors and the mechanism of corrosion inhibition was conducted. Subsequently, the corrosion inhibition effect of acylhydrazide corrosion inhibitors was evaluated using the hydrazinolysis reaction between vegetable oil and hydrazine hydrate, employing both the static weight loss method and electrochemical techniques. The corrosion rate and corrosion inhibition rate of steel sheets immersed in simulated corrosion solutions were quantified. Moreover, dynamic potential polarization curve and electrochemical impedance spectroscopy were utilized to examine the performance of different concentrations of corrosion inhibitors in the simulated corrosion solution. This comprehensive experiment not only enables students to comprehend the corrosion inhibition mechanism of these inhibitors, but also equips them with knowledge of electrochemistry principles and the operational skills required for electrochemical workstations. Through numerical calculations and data analysis, students are able to evaluate the efficacy of various corrosion inhibitors and elucidate the underlying factors influencing parameter variations. The integration of organic chemistry knowledge with practical applications in oilfield chemistry elevates students' professional proficiency and their ability to adapt to real-world oilfield scenarios. Furthermore, this experiment enables students to proficiently employ corrosion evaluation methods and effectively process relevant data across different corrosive environments. |
