在生物精炼过程中，下游加工通常是整体高效率的技术瓶颈。基于最近的发展，应用高度疏水多孔材料的选择性液相吸附为工艺开发开辟了新的机会。在这方面的贡献，选择性液相吸附的效率证明了从水溶液中的分离和纯化的衣康酸为第一次。筛选了各种不同的吸附剂，揭示了表面极性以及质地特性作为其性能的关键参数。从混合溶液的衣康酸和葡萄糖的吸附表现出非常高的选择性吸附剂具有高度疏水性的表面，特别是某些活性炭和超交联聚合物。pH依赖性的评价表明，衣康酸/衣康酸盐的各自的分子种类对吸附性能具有重大影响。艾迪
In biorefinery processes often the downstream processing is the technological bottleneck for an overall high efficiency. On the basis of recent developments, the selective liquid phase adsorption applying highly hydrophobic porous materials opened up new opportunities for process development. In this contribution, the efficiency of selective liquid phase adsorption is demonstrated for the separation and purification of itaconic acid from aqueous solutions for the first time. A wide range of different adsorbents was screened, revealing the surface polarity as well as textural properties as critical parameters for their performance. Adsorption from mixed solutions of itaconic acid and glucose exhibited extraordinary high selectivities for adsorbents with highly hydrophobic surfaces, especially certain activated carbons and hyper-cross-linked polymers. Evaluation of the pH dependence showed that the respective molecular species of itaconic acid/itaconate has a major impact on the adsorption performance. Addi...
