摘要:一系列双(酰化物)与酰氯的反应已用于制备双(氧酰化物)11-15.同样,一系列简单的叶立德与双(酰氯)反应,生成具有异构体结构的双(氧酰)19-27.第一种类型的快速真空热解(fvp)导致ph 3 P挤出,而不是预期的ph 3 Po挤出,而第二种类型的六个实例确实在500oc的fvp压力下挤出ph 3 Po以获得双(炔烃)28.还已经制备了相应的双(三丁基phosph)的实例,但是使用逐步方法构建四(氧代酰)31的尝试是失败的.完全分配给出了其中的六个双(氧酰化物)的13 C NMR光谱.

摘要:A poly(arylene ether)-polysiloxane multiblock copolymer is prepared by the reaction of a hydroxy-diterminated poly(arylene ether), a hydroxyaryl-diterminated polysiloxane, and an aromatic diacid chloride. This synthesis overcomes disadvantages of known syntheses of poly(arylene ether)-polysiloxane block copolymers. The poly(arylene ether)-polysiloxane multiblock copolymer is useful for improving the melt processability of poly(arylene ether) compositions.

标 题 :Composite covalent organic framework membranes
发明人：BIKSON BENJAMIN

摘要:Disclosed is the preparation of composite fluid separation membranes based on poly (aryl ether ketone) (PAEK) polymers with the separation layer formed by a layer-by-layer reticular synthesis. The porous PAEK substrate is semicrystalline, exhibits a mesoporous surface structure, and is surface functionalized. The separation layer formed by the hierarchical layer-by-layer process is in the form of a covalent organic network integrally linked via covalent bonds to the functional groups of the substrate. The composite separation layer may be synthesized in situ in a preformed separation device on the surface of the PAEK substrate. Device configurations include flat sheet, spiral wound, monolith, and hollow fiber configurations with the hollow fiber configuration being preferred. Hollow fibers are formed from PAEK polymers with poly (ether ether ketone) and poly (ether ketone) particularly preferred. Composite PAEK membranes of the present invention are useful for a broad range of fluid separation applications.

摘要:Synthesis and use of a new class of polymeric materials with favorable separation characteristics for the dehydration of ethanol and other organic solvents is described herein. The thermally rearranged (TR) polybenzoxazole (PBO), polybenzimidazole (PBI) and polybenzothiazole (PBT) membranes of the present invention can be used for the dehydration of ethanol during processing to fuel grade biodiesel by either pervaporation or vapor permeation. The unique microstructure of the membranes provides excellent separation characteristics, and this, coupled with their inherent thermal and chemical stability, enables their usage in other separations, such as the dehydration of other organic solvents.
