摘要：为了实现高浓度的过氧乙酸安全连续合成,首先在间歇反应器内研究了60～80℃和高浓度过氧化氢条件下过氧乙酸合成的反应动力学,并建立了反应速率方程。之后在石英微通道反应器内进行了高浓度过氧乙酸的连续合成。研究表明:建立的动力学方程能很好预测微通道内的反应结果;石英毛细管壁不影响过氧化氢和过氧乙酸的稳定性。使用高浓度过氧化氢并在较高温度下合成过氧乙酸,可将反应时间缩短到10～15 min。
For safe and continuous synthesis of concentrated peracetic acid （mass fraction more than 25%）, kinetics of peroxidation of acetic acid with concentration hydrogen peroxide （mass fraction 60%） was studied in a glass batch reactor at 60-80 ℃ and the reaction rate equation was established. Continuous synthesis of peracetic acid in a silicon capillary was carried out and the results showed that the concentration of peracetic acid could be well predicted by the reaction kinetics, which indicated that the surface of micro-channel did not accelerate the decomposition of hydrogen peroxide and peracetic acid and catalyze the peroxidation. Because the peroxidation was carried out at high temperature and with concentrated hydrogen peroxide, reaction went near to equilibrium in 10-15 min.
