两亲性化合物1,3,5-三取代苯的合成及气体透过性质的研究

Synthesis of an amphiphilic 1,3,5-trisubsitituted benzene and study on the oxygen permselectivity of blend membrane

合成了新型苯乙炔衍生物EODHPA。在温和条件下,通过聚合,光环化(SCAT)等反应,高效合成了两亲性化合物1,3,5-三取代苯(T-EO),并通过1HNMR确认化合物结构。以T-EO为添加物,PVA为基质膜制备混合膜,并对其氧气选择透过性能进行研究,结果表明,此混合膜T-EO/PVA具有气体透气量高,氧气选择透过性强等优点。

The new monomer EODHPA was synthesized successfully and the 1,3,5-trisubstituted benzene(T-EO) was synthesized by highly selective photocyclic aromatization reaction(SCAT)under the facile condition, structure of the compounds were confirmed by 1HNMR. T-EO was used as the additiver and PVA as base membrane to fabricate blend membranes. study on oxygen permselectivity and the results show that the high permeability coefficient and high separation factor blend membranes(T-EO/PVA)have been fabricated.
