FIELD: chemistry. n SUBSTANCE: present invention relates to ionic liquids based on a cation of formula (1): where substituting groups R 1 -R 9 are selected from hydrogen, alkyl; any carbon atom in R 1 -R 9 can be substituted with a -O-, -C(O)-, -C(O)O-, -S-, -S(O)-, -SO 2 - or -SO 3 - group; X is S, O or C; R 8 and R 9 exist only when X is carbon; the anion is selected from [RSO 3 ] - , [R f SO 3 ] - , [(R f SO 2 ) 2 N] - , [(FSO 2 ) 3 C] - , [RCH 2 OSO 3 ] - , [RC(O)O] - , [R f C(O)O] - , [CCl 3 C(O)O] - , [(CN) 3 C] - , [(CN) 2 CR] - , [(RO(O)C) 2 CR] - , [B(OR) 4 ] - , [N(CF 3 ) 2 ] - , [N(CN) 2 ] - , [AlCl 4 ] - , PF 6 - , BF 4 - , SO 4 2- , HSO 4 - , NO 3 - ; where R is hydrogen, halogen, alkyl, alkenyl, alkynyl, cycloalkyl, R f is a fluorine-containing substituting group. n EFFECT: obtaining new ionic liquids with improved electrochemical properties. n 15 cl, 18 ex, 2 dwg |
