Ionic liquids,which are also referred to as room temperature ionic liquids,room temperature molten salts(RTILs),organic ionic liquids,etc.refer to an ionic system which takes on a liquid state at the room temperature or slightly warmer.They are salts composed of organic nitrogen inorganic cations and inorganic anions [38–40].
As a promising class of new solvents,cation types of ionic liquids which have been studied (Fig.1) include:A) alkyl quaternary ammonium cation[NRXH4 .X]+; B) alkyl quaternary phosphonium cation [PRXH4 .X]+; C) N-alkyl pyridine cation[RPy]+; and D) N,N-2- alkyl imidazole cation[R1 R3im]+,in which im represents the imidazole structure,(if substituting group-R is at the 2-position,the structure would be indicated which is expressed with [R1R2Rim]+).As is shown in Fig.1,the cations are usually alkylsubstituted imidazole.Anions such as BF.4,PF.6,CF3 SO3 .,(CF3SO2) 2N.,C3F7CO0.,C4F9SO3 .,CF3COO.,ClO4 .can be used in combination with the above cations to form low melting point liquids [41].Most of the cations are 1-alkyl-3-methylimidazolium cations with the chemical structures as shown in Fig.2.The dissolution mechanismof cellulose in ionic liquids [42] involves the oxygen and hydrogen atoms of cellulose-OH in the formation of electron donor-electron acceptor (EDA) complexes which interact with the ionic liquid (Fig.3).For their interaction,the cellulose atoms serve as electron pair donor and hydrogen atoms act as an electron acceptor.In corresponding fashion,the cations in ionic
liquid solvents act as the electron acceptor center and anion as electron-donor center.

离子液体,它也被称为室温离子液体,指离子体系等方面,呈现出一种液态在室温或稍微温暖.他们是盐组成的无机阳离子氮有机和无机阴离子(38-40].作为一个有前途的一类新型溶剂,阳离子型离子液体所研究(图1),包括:1)烷基季铵盐阳离子[NRXH4.X)+;B)烷基季含磷阳离子[PRXH4.X)+摄氏度)N-alkyl吡啶(RPy]+、阳离子、N-2和D -烷基聚阳离子(R1 R3im]+,我代表了聚苯胺的结构,(如果替代group-R在2-position会指出,结构和主要表现R1R2Rim]+).作为图1显示的是,通常是alkylsubstituted阳离子
