摘　　要：用自制的PVA/PAN复合膜进行了渗透汽化丁酮甲苯混合溶剂脱水试验 ,并与模型预测脱水极限值进行了比较 。The dehydration of butanone-toluene-water mixed solvents by pervaporation were carried out. The membrane used in the experiments was PVA/PAN composite membranes prepared in our laboratory. The experimental results were compared with those from the model prediction.
