N,N,N-trimethyl-1-adamantylammonium hydroxide (TMAdaOH) is an organic alkali compound with important applications in the catalyst industry. In this study, bipolar membrane electrodialysis (BMED) was employed for the preparation of TMAdaOH from its halide with a BP-C1-A1-C2-BP four-compartment configuration. The effects of operating conditions (feed concentration and current density) on the performance of BMED were investigated. The results indicated that at optimum operational conditions (feed concentration of 0.3 mol/L and current density of 8 mA·cm⁻²), a conversion rate of 76.8% can be obtained, with an energy consumption of only 3.22 kWh/kg. The purity of product is extremely high and Cl⁻ content in the TMAdaOH solution can reach as low as 68 ppm. Due to the importance of cation-exchange membrane to the process, different types of cation membrane were compared. In addition, repeated experiments were conducted to prove the stability of BMED process.

N，N，N-三甲基-1-金刚烷铵氢氧化物（TMAdaOH）是有机碱化合物，在催化剂工业中具有重要的应用。在这项研究中，双极膜电渗析（BMED）用于从卤化物以BP-C1-A1-C2-BP四室构型制备TMAdaOH。研究了操作条件（进料浓度和电流密度）对BMED性能的影响。结果表明，在最佳操作条件下（进料浓度为0.3 mol / L，电流密度为8 mA·cm ^-2），可获得76.8％的转化率，能耗仅为3.22 kWh / kg。产品的纯度极高和Cl ^-TMAdaOH溶液中的含量可低至68 ppm。由于阳离子交换膜对工艺的重要性，因此对不同类型的阳离子膜进行了比较。此外，进行了重复实验以证明BMED工艺的稳定性。
