Adiponitrile (ADN) is an important raw material to produce nylon 66, and can be produced by electrodimerization of acrylonitrile (AN). The commercial processes are operated in flow systems. It is the first time that a rotating rod electrode (RRE), a relatively simple tool, was applied in the electrosynthesis of ADN. The electrode rotation rate was used to simulate high electrolyte velocity in the flow cell systems used in the industry. In addition to AN and ADN, the concentrations of two major by-products, propionitrile (PN) and trimer, were measured to determine the selectivity and current efficiency. Among five investigated quaternary ammonium salts in the electrolyte, tetrabutylammonium hydroxide (TBAP) possessing the smallest hydrophilic ability and hydrophilic-lipophilic balance (HLB) showed the best performance in the selectivity and current efficiency of ADN. A higher electrode rotation rate provided faster mass transport of AN and promoted the production of oligomers, particularly ADN. Higher current density favored the production of PN. The highest selectivity (85%), current efficiency (82%) and highest yield (0.331 g/cm²·hr) of adiponitrile were accomplished at 3000 rpm, corresponding to a velocity of 1.25 m/s in the range of the electrolyte flow velocity in commercial processes that other researches cannot easily reach it.

己二腈（ADN）是生产尼龙66的重要原料，可以通过丙烯腈（AN）的电二聚化生产。商业流程在流系统中操作。这是首次将旋转棒电极（RRE）（一种相对简单的工具）应用于ADN的电合成。电极旋转速度用于模拟工业中使用的流通池系统中的高电解液速度。除AN和ADN外，还测量了两种主要副产物丙腈（PN）和三聚体的浓度，以确定选择性和电流效率。在电解质中研究的五种季铵盐中，具有最小的亲水性的氢氧化四丁基铵（TBAP）和亲水-亲脂性平衡（HLB）在ADN的选择性和电流效率方面表现出最好的性能。较高的电极旋转速度提供了更快的AN质量转移，并促进了低聚物，特别是ADN的生产。较高的电流密度有利于PN的生产。最高的选择性（85％），电流效率（82％）和最高的产量（0.331 g / cm在3000 rpm的条件下，己二腈的反应速率为² ·hr），相当于商业化过程中电解液流速范围内的1.25 m / s速度，这是其他研究无法轻易达到的。
