项目摘要

The adsorption of volatile anesthetics on trace levels (< 1 ppm) is highly interesting for technical applications as well as for academic research. Especially challenging for these trace levels is the lack of real adsorption data, while practically adsorption isotherms for higher concentrations (mostly several hundred ppm) are linear extrapolated towards their point of origin to gather data. Therefore, the selection or synthesis of an adsorbent matching these requirements is a particular challenge.During the second founding period carbon based adsorbents as well as large spherical PMO particles with a hierarchical pore structure were synthesized on the basis of porous micro glass beads for the first time. Especially the PMO materials exhibited a very high adsorption capacity for hexanal. First adsorption experiments of volatile anesthetics (isoflurane) directed the material design towards large spherical hydrophobic and hierarchical micro/mesoporous particles (carbon or PMO) for significant process intensification.The most important target for the third founding period of this joint project will be the synthesis of spherical porous glass with flexible properties in the existing mini plant fluidized bed reactor. To insert the advantageous features of core shell particles into the existing system the principle of ion exchange induced phase separation will be applied. To rise particle sizes in technically relevant range the principle of ionotropic gelation will be combined with sodium borosilicate glass for the first time. Subsequently, these shaped bodies will be transformed into ordered micro/mesoporous hierarchically structured organosilica or carbon beads. Furthermore, the new route of ionotropic gelation will be utilized for the direct synthesis of well-ordered microporous organosilica or carbon beads. In the last step, the innovative materials will be tested in several adsorption experiments. The three most common volatile anesthetics (isoflurane, desflurane, sevoflurane) will be applied. Additionally, three alkyl ethers and one alkane will be tested to distinguish between the effects of the halogen atoms and the influence of the ether bridge. Air filter systems are in the focus of this project. Therefore, only trace level concentrations of the three fluranes in an air/nitrogen mixture will be studied.

对于技术应用以及学术研究，浪漫性麻醉药的吸附在痕量水平上（<1 ppm）非常有趣。对于这些痕量水平，尤其是具有挑战性的是缺乏实际的吸附数据，而实际上较高浓度的吸附等温线（大多数是数百ppm）是线性推断的，以收集数据来收集数据。因此，与这些要求相匹配的吸附剂的选择或合成是一个特殊的挑战。在第二个基于碳的吸附剂以及具有分层孔结构的大型球形PMO颗粒和大型球形PMO颗粒是根据多孔微型玻璃珠的基础综合的。尤其是PMO材料的六角形具有很高的吸附能力。挥发性麻醉药（异氟烷）的第一个吸附实验将材料设计定向了大球形疏水性和分层微型/介孔颗粒（碳或PMO），以实现重大过程强化。该关节项目的第三个建立期最重要的目标是与现有的柔性玻璃的合成。为了将核心壳颗粒的有利特征插入现有系统中，将应用离子交换的原理。在技术相关范围内，颗粒大小的升高原理将首次与硼硅酸钠玻璃结合使用。随后，这些形状的身体将被转换为有序的微/介孔层次结构的有机硅或碳珠。此外，将使用新的离子凝胶化途径来直接合成良好的微孔有机硅或碳珠。在最后一步中，将在几个吸附实验中测试创新材料。将应用三种最常见的挥发性麻醉药（异氟烷，desflurane，sevoflurane）。此外，将测试三个烷基醚和一种烷烃，以区分卤素原子的作用和醚桥的影响。空气滤清器系统是该项目的重点。因此，仅研究空气/氮混合物中三个氟烷的痕量水平浓度。
