FIELD: chemistry. ^ SUBSTANCE: invention relates to ionic liquid used in electrical energy accumulation devices and as a solvent which contains a cation of general formula where X1, X2 and X3 denote N, O, S or C; R1-R11, X1, R1, R2 and R3, X2, R6, R7 and R8, X3, R9, R10 and R11 can form ring structures; the anion is selected from [RSO3]-, [RfSO3]-, [(RfSO2)2N]-, [(RfSO2)3C]-, [(FSO2)3C]-, [ROSO3]-, [RC(O)O]-, [RfC(O)O]-, [CCl3C(O)O]-, [(CN)3C]-, [(CN)2CR]-, [(RO(O)C)2CR]-, [R2P(O)O]-, [RP(O)O2]2-, [(RO)2P(O)O]-, [(RO)P(O)O2]2-, [(RO)(R)P(O)O]-, [Rf2P(O)O]-, [RfP(O)O2]2-, [B(OR)4]-, [N(CN)2]-, [AlCl4]-, PF6Çè-, [RfPF5]-, BF4Çè-, [RfBF3]-, SO4Çè2-, HSO4-, NO3- I-, bis(oxalate)borate; R, R1-R11 are selected from hydrogehn, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl and heterocyclyl, halogen, CN- or NO2-; the carbon in R and R1-R11 can be substituted with O-, -Si(R')2-, -C(O)-, -C(O)O-, -S-, -S(O)-, -SO2-, -SO3-, -N= -N=N-, -NH-, -NR'-, -N(R')2-, -PR'-, -P(O)R4 -P(O)R'-O-, -O-P(O)R'-O- and -P(R')2=N-; where R' denotes alkyl, fluoroalkyl, cycloalkyl, cycloalkenyl, cycloalkynyl, phenyl or heterocyclyl; Rf denotes a fluorine-containing substitute. ^ EFFECT: obtaining novel ionic liquids which are stable in liquid state in a wide temperature range. ^ 14 cl, 76 ex, 3 dwg |
