摘要
双核酸性离子液体以双核阳离子结构为基础,通过嫁接 2个磺酸基使其具有较强的催化活性和较高的稳定性,在取代强腐蚀性的工业传统酸方面具有较大的应用潜力.设计合成了以三乙烯二胺为双核阳离子的5种双核酸性离子液体,并通过核磁共振光谱(NMR)和红外光谱(FT-IR)确定了离子液体的结构,进一步利用紫外分光光度计(UV-vis)测定其酸度(H0),并探究了双核离子液体结构与酸度之间的关系.
Abstract
Dual-core acidic ionic liquid is based on Dual-core cation structure,and it has strong catalytic activity and high stability by grafting two sulfonic acid groups,so it has great application potential in replacing strong corrosive industrial traditional acids.Five dual-core sulfonic acidic ionic liquids with triethylenediamine as the cation were designed and synthesized,they were characterized by nuclear magnetic resonance spectroscopy(NMR)and infrared spectroscopy(FT-IR).In addition,their acidity(H0)was determined by UV spectrophotometry,and the relationship between the structures and acidity of the ionic liquids was investigated.
