Title:
IONIC LIQUID COMPOSITION AS HYDRAULIC HYDROGENATION WORKING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/126915
Kind Code:
A1
Abstract:
Disclosed is an ionic liquid composition as a hydraulic hydrogenation working medium, comprising: 100 parts by mass of an ionic liquid and 0 to 5 parts by mass of an additive, wherein the general formula (I) of the ionic liquid is as follows: wherein R 1 and R 2 are the same or different and are respectively selected from C1-4 saturated alkyl groups; and [R 2-SO 4] - is a methyl sulfate anion, an ethyl sulfate anion, a propyl sulfate anion or a butyl sulfate anion. Experiments have proved that the ionic liquid not only has an excellent thermal stability, but also has an extremely low volatility, which can prevent hydrogen from being dissolved in the composition, and same has also achieved remarkable results, solved problems in the field, and made breakthrough developments in this field.
