Patent ID: 8309740

Claim:
A preparation method for one-pot synthesis of ionic liquid with fluoroalkyl group represented by the following Chemical Formula 1 by reacting a nitrogen-containing compound with a Brønsted acid of the formula YH, and followed by reacting with a fluoroolefin compound of the formula CFR 1 =CR 2 R 3 in a single reactor, wherein no metal halide byproduct is formed and no anion exchange step is carried out: wherein represents a nitrogen-containing compound as a tertiary amine, which is a five- or six-membered heterocyclic compound having from 1 to 3 nitrogen atoms, and optionally substituted by a substituent selected from C1-C10 alkyl, C1-C4 alkyl having from 1 to 8 halogen atoms, C2-C10 alkenyl and C2-C10 alkynyl or unsubstituted; R 1 , R 2 and R 3 , which may be same or different, represent hydrogen, fluorine, C1-C10 alkyl or C1-C10 fluoroalkyl having from 1 to 8 fluorine atoms; and Y represents, BF4, PF6, (CF3SO)2N, NO2, NO3, CF3CO2 or CH3CO2.
