采用双极膜（BPM）电渗析（艾德）从水杨酸钠中制备水杨酸。使用膜面积为40 cm（2）的实验室ED电池测试工艺可行性。比较了两种商品化双极膜（德山碱和Stantech膜）的性能。两种双极膜生产水杨酸和苛性钠的电流效率接近（80-90%），但在与膜的电特性相关的能量消耗方面观察到差异。
Production of salicylic acid from sodium salicylate was carried out by electrodialysis (ED) using bipolar membranes (BPM). The process feasibility was tested using a laboratory ED-cell with a membrane area of 40 cm(2). The performances of two commercial bipolar membranes (Tokuyama Soda and Stantech membranes) are compared. Current efficiencies for salicylic acid and caustic soda production are close for both bipolar membranes (80-90%), but differences are observed with respect to energy consumption which are related to the electrical characteristics of the membranes.
