Title:
HYDROPHILIC ROOM-TEMPERATURE IONIC LIQUID AND USE THEREOF
Document Type and Number:
Japanese Patent JP2014131974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel ionic liquid that has a cation structure apt to become liquid, and is highly hydrophilic, particularly highly water-soluble, and use thereof.SOLUTION: This invention provides a hydrophilic room-temperature ionic liquid including a cation and an anion, the cation being a quaternary ammonium cation of the formula (I), where Rs independently represent a 2-8C straight-chain or branched-chain polyhydroxyalkyl group having two or more hydroxy groups, Rs independently represent a hydrogen atom or a 1-5C straight-chain or branched-chain monohydroxyalkyl group, and n represents an integer of 1-4.
