A flow electrolysis cell that enables operation at high temperatures and pressures has been designed and developed. The cell, with a cylindrical shape and concentric electrodes, can be easily assembled using commercially available fluidic components. The compact design of the device permits easy temperature control using a commercial column heater. Temperatures ranging from −10 °C to +150 °C and pressures up to 70 bar have been successfully applied for long operation periods. The cell performance has been evaluated using the anodic methoxylation of N ‐formylpiperidine as a model. Very high conversions and selectivities have been achieved with single‐pass processing, and high productivities of 73 mmol/h with electrolyte recycling. The high pressure and temperature capabilities of the cell have been used to demonstrate the negative effect that re‐dissolved hydrogen gas can have on hydrogen‐releasing electrochemical reactions in undivided cells, owing to undesired anodic oxidation of hydrogen.

用于高温/高压有机合成的连续流动池

已经设计和开发了能够在高温和高压下操作的流式电解槽。具有圆柱形状和同心电极的电池可以使用市售的流体组件轻松组装。该设备的紧凑设计允许使用商用柱加热器轻松控制温度。-10°C至+150°C的温度范围和最高70 bar的压力已成功应用了很长时间。已使用N的阳极甲氧基化评估了电池性能-甲酰基哌啶为模型。单程处理可实现非常高的转化率和选择性，而电解液再循环可实现73 mmol / h的高生产率。电解池的高压和高温性能已被用来证明，由于氢的不希望发生的阳极氧化，重新溶解的氢气会对未分离的电解池中释放氢的电化学反应产生负面影响。
