为构建面向环己烷氧化过程的渗透汽化膜反应器,依据溶度参数理论对环己醇(酮)/环己烷渗透汽化分离膜材料进行了初步选择。通过构建30种常见聚合物和3种溶剂的二维浓度参数图、考虑氢键作用的影响以及综合分析δ的矢量形式差和模数,初步得出了PA-66、PVP、PEG、CTA和CA为较适宜的膜材料。
To design a novel pervaporation membrane reactor for cyclohexane oxidation,based on the solubility parameter theory,solubility interactions between polymers and solvents were compared to select potential appropriate membrane materials for the separation of cyclohexanol(cyclohexanone)/cyclohexane mixtures.Solubility interactions between thirty polymers and the three solvents,i.e.cyclohexanol,cyclohexanone and cyclohexane,were plotted using the combined component parameter and the hydrogen(H) bonding component parameter.Hydrogen-bonding interaction and the distance between the vector end point of solvents and polymers were investigated.From the preliminary analysis,PA-66,PVP,PEG,CTA and CA were considered to be potential appropriate membrane materials.
