摘要
新芳香的肼， 3,5-diaminobenzoylpiperazine (3,5-DABP ) ，从 3,5-diaminobenzoic 酸和 1 甲酰 piperazine 被综合。3,5-DABP 的结构被英尺红外系列和 1H NMR 系列识别。与是的 3,5-DABP 水的单体和 trimesoyl 氯化物(TMC ) 作为器官的单体，薄电影合成(TFC ) nanofiltration 膜被界面的聚合技术准备。这些 TFC 膜的盐拒绝顺序是 Na2SO4 > MgSO4 > MgCl2 > NaCl。这个序列显示膜否定地被控告。
A new aromatic diamine,3,5-diaminobenzoylpiperazine （3,5-DABP）,was synthesized from 3,5-diaminobenzoic acid and 1-formyl piperazine.The structure of 3,5-DABP was identified by FT-IR spectra and 1H NMR spectra.With 3,5-DABP as aqueous monomer and trimesoyl chloride （TMC） as organic monomer,thin film composite （TFC） nanofiltration membranes were prepared by interfacial polymerization technology.The salt rejection order of these TFC membranes is Na2SO4MgSO4MgCl2NaCl.This sequence indicates that the membranes are negatively charged.
