Abstract:
The present invention relates to salts comprising novel aryl-alkyl-substituted imidazolium and triazolium cations and arbitrary anions. The invention further relates to methods for the chemical conversion and separation of substances, comprising the salts according to the invention as solvents, solvent additives, or extraction means, and to the use of the salts according to the invention, for example as solvents or solvent additives in chemical reactions, as extracting agents for the separation of substances, or for storing hydrogen. According to the invention, the object is achieved by salts of the general formula (I), where X— is an anion, Y1 and Y2 are CH, or Y1 is CH and Y2 is N, or Y1 is N and Y2 is CH, n is a number from 1 up to an including 18, Q is selected from —CH3, —OH, —ORx, —S03H, —S03Rx, —COOH, —COORx, —CORx, NH2, —NHRx, —N(Rx)2, and —CH(Rx)2, Z is H or Rx, R1, R2, R3, R4 and R5 independently from each other are —H, -halogen, —N02, —NH2, —NHRx, —N(Rx)2, —Rx, —COORx or —ORx, where Rx is an optionally substituted and/or branched C1 to C18-alkyl group, excluding compounds of the general formula (I), where Y1 and Y2 are CH and R1, R2, R3, R4 and R5 are H, excluding compounds of the general formula (I), where Y1 and Y2 are CH, R1=R3=R5=CH3 is true, n=1, 2, 6 and Q=CH3 is true, excluding compounds of the general formula (I), where Y1 is CH and Y2 is N, R1, R2, R3, R4 and R5 are H, n=1 is true, and Q=CH3 is true, and excluding compounds of the general formula (I), where Y1 and Y2 are CH, R1, R2, R4, R5=H is true, R3=ORx is true, and Rx is a hydrocarbon having 3 or 12 carbon atoms.
