Novel Polymer Affinity Membranes for Organic-Organic Pervaporation Separation

摘要本项目的目的是制造一种新型聚合物膜，用于通过渗透蒸发分离某些非极性有机物。这种增强富电子烯烃和芳烃有机化合物选择性的新方法的核心是在靶分子和膜内亲和物质之间形成电子供体-受体复合物。与芳烃形成配合物的马来酰亚胺或邻苯二甲酸亚胺等部分被纳入聚合物基体结构中。各种衍生化聚合物和具有不同浓度的亲和基团的膜将被测试用于分离苯乙烯和乙苯以及其他工业上重要的混合物。美国化工厂和炼油厂的大部分能源需求可归因于蒸馏过程中的能量损失。新膜的开发可以替代更节能的分离技术，这样美国公司就可以降低成本，更好地竞争。ıı !!！% !苹果激光书写器II NT LPT3：pscript苹果激光打印机II NT D D D D， X Z e " h 1尼克尔·科沃德尼克尔·科沃德

CTS-9300190 Oregon Graduate Institute of Science & Technology David W. Grainger ABSTRACT The objective of this project is to fabricate novel polymeric membranes for the separation of certain nonpolar organics by pervaporation. Central to this new approach for enhanced selectivity of electron-rich alkene and arene organic compounds will be the formation of electron donor-acceptor complexes between the target molecules and affinity species within the membrane. Moieties like maleimide or phthalimide that form complexes with aromatics are to be incorporated into polymer matrix structures. Membranes of various derivatized polymers and with differing concentrations of these affinity groups will be tested for the separation of styrene and ethylbenzene and other industrially important mixtures. Much of the energy requirements in the United States chemical plants and petroleum refineries can be attributed to energy losses during distillation. The development of new membranes could allow the substitution of more energy efficient separation techniques so that American corporations have lower costs and are better able to compete. ı ı ! ! !% !
