摘要： 研究了N-异丙基羟胺(IPHA)与去离子水中游离氧反应的动力学. 以15% NaOH水溶液为pH调节剂，通过考察不同pH值、反应温度和IPHA用量下水中游离氧浓度随时间的变化规律，建立了IPHA除氧反应动力学模型，经过数据分析及反应机理研究对所建动力学模型进行简化，推导出IPHA与游离氧反应的动力学方程，该反应为假一级动力学反应，反应的活化能为Ea=71.09052 kJ/mol. 根据化学动力学研究结果得到了在弱碱性条件下IPHA具有与水中游离氧反应速度快、反应所需活化能低等特点，进一步证实了IPHA具有良好的还原性.

Abstract: The kinetics of the reaction of N-isopropyl hydroxylamine (IPHA) and free oxygen in deionized water was studied. With 15% NaOH aqueous solution was used as a pH adjuster. By observing the variation of free oxygen concentration in water with time under different pH values, different reaction temperatures and different IPHA dosages, a kinetic model of IPHA deoxygenation reaction was established. After the analysis of the data on oxygen concentration over time under different conditions and study on the reaction mechanism of the reaction free oxygen in water with IPHA, the established kinetic model was simplified and optimized. Meanwhile this kinetic equation of the reaction between IPHA and free oxygen was deduced. After the analysis of the data on oxygen concentration over time under different conditions，this reaction was a pseudo first order reaction and the activation energy of the reaction was Ea=71.09052 kJ/mol. In this system of reaction, a certain concentration of hydroxide ions would strongly promote the reaction of IPHA and free oxygen in water. However, the concentration of hydroxide ions in the system before and after the reaction remains basically unchanged. Based on the study of chemical kinetics of the reaction free oxygen in water with IPHA, this results of the reaction free oxygen in water with IPHA under weakly basic conditions IPHA had features of fast reaction rate, and low activation energy required for the reaction, it was further confirmed IPHA having good reducibility. This work fills the gap between the domestic and international deoxygenation kinetics of IPHA, and provides a reliable theoretical basis for the industrial application of IPHA as an oxygen scavenger. At the same time, a certain pilot work has been done for the application of the redox initiation system of the subsequent IPHA in acrylic series aqueous solution radical polymerization in this process.

Key words: N-isopropylhydroxylamine, IPHA, oxygen scavenger, free oxygen, kinetics, activation energy
