Abstract

... Catalysis Letters. ... Therefore, the catalytic performance depends very much on the Brönsted acidity of catalyst. In order to prove the consistency of the catalysts' activity with their acidity, the acidities of these three SO 3 H-functionalized ILs have been examined using 4-nitroanline ...
