Title:
IONIC LIQUID, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/047493
Kind Code:
A1
Abstract:
The present invention relates to an ionic liquid, a cation of which contains a hexafluoroisopropylsulfonic acid group. The ionic liquid provided by the present invention introduces a hexafluoroisopropylsulfonic acid group into a cationic moiety thereof, imparting an ultra-strong acid center to the ionic liquid, and obtains an ionic liquid having an acidity higher than that of 98% concentrated sulfuric acid by adjusting the composition of an anion and the cation. The Hamlet acidity (H0) of the resulting ionic liquid can reach -14.13.
