Title:
IONIC LIQUID CONTAINING ALLYLSULFONATE ANION
Document Type and Number:
WIPO Patent Application WO/2011/024988
Kind Code:
A1
Abstract:
Disclosed is a novel ionic liquid which can be produced at low cost, is safe for the environment, and has a low viscosity and a low melting point. Specifically disclosed is an ionic liquid represented by general formula [1] (wherein R1 to R3 and n R4s independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R5 to R7 independently represent an alkyl group, an aralkyl group or an allyl group; R8 represents an alkyl group, an aralkyl group, an allyl group, or a group represented by general formula [2] (wherein T represents an alkylene chain having 1 to 8 carbon atoms; and R1 to R7 and n are as defined above); X represents a nitrogen atom or a phosphorus atom; and n represents 1 or 2, wherein R3 and R4 may be bound to each other to, together with an adjacent carbon atom, form a cyclohexene ring when n is 1, and R5 to R7 or R5 to R6, together with a nitrogen atom to which these groups are bound, may form a heteroring when n is a nitrogen atom).
