本文研究了丙烯酸在两种不同阴离子交换膜（JAM-I-10和ACM均相膜）中的扩散特性。试验结果表明，温度和丙烯酸浓度对丙烯酸在JAM-I-10和ACM均相膜中传质的影响规律一致。在温度15～30℃之间，传质系数随温度的升高而增大，符合阿累尼乌斯方程。在温度20℃，酸室丙烯酸初始浓度为0.5～4.0mol/L条件下，传质系数随丙烯酸浓度变化不大；同等条件下，丙烯酸在ACM均相膜中的传质系数明显低于JAM-I-10均相膜。

the mass transfer characteristics of the acrylic acid in two different anion exchange membranes (JAM-I-10 and ACM homogeneous membrane) were studied. It was indicated that the effect of temperature and acrylic acid concentration on mass transfer coefficient across JAM-I-10 and ACM membranes was the same. In the range of 15 to 30℃, the mass transfer coefficient increased with the increase of the temperature and followed the Arrhenius' Equation. At the temperature of 20℃, when the concentration of acrylic acid increased from 0.5mol/L to 4.0mol/L, the mass transfer coefficient changed little. Under the same condition, the mass transfer coefficient of acrylic acid in the ACM homogeneous membrane was significantly lower than that in the JAM-I-10 homogeneous membrane.
