Ambient-temperature molten salts and process for producing the same

摘要

Ambient-temperature molten salts of formula (I):; wherein Y⁺ is a cation selected from the group consisting of an ammonium ion, a sulfonium ion, a pyridinium ion, a(n) (iso)thiazolium ion, and a(n) (iso)oxazolium ion that may be optionally substituted with C_1-10 alkyl and/or C_1-10 alkyl having ether linkage, provided that the above cation has at least one substituent of —CH₂Rf¹ or —OCH₂Rf¹ (wherein Rf¹ is C_1-10 perfluoroalkyl); Rf² and Rf³ are independently C_1-10 perfluoroalkyl or may together form C_1-4 perfluoroalkylene; and X is —SO₂— or —CO—.
