Title:
IONIC LIQUID AND METHOD OF REACTION USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/028446
Kind Code:
A1
Abstract:
A novel acidic ionic liquid which is useful as a catalyst for alkylation, nitration, Beckmann rearrangement, etc. and is stable to air and water. It is an ionic liquid represented by the following formula (1): (1) wherein X represents halogeno or hydroxy; Y- represents CF3SO3-, BF4-, PF6-, CH3COO-, CF3COO-, (CF3SO2)2N-, (CF3SO2)3C-, F-, Cl-, Br-, or I-; n is an integer of 2 to 16; and R represents methyl, allyl, or vinyl. This ionic liquid not only functions as a BrDnsted acid or a Lewis acid but is a liquid insoluble in many organic solvents. The liquid is hence useful as a catalyst or solvent for Friedel-Crafts reaction, nitration, and Beckmann rearrangement. It can be easily separated from the reaction mixture and reused.
