Abstract:
Researchers synthesized 56 ionic liquids in
parallel format under one-pot, solvent-free microwave assisted synthesis. The
compounds were evaluated as extracting agents of nitrogen-containing compounds
from a real Diesel feed before being submitted to the hydrodesulfurization
process to obtain ultralow sulfur Diesel.
Results demonstrate that halogenated ionic
liquids are an excellent alternative.
This is due to the fact that these ionic liquids are relatively
inexpensive, present a high selectivity for the extraction of nitrogen-containing
compounds and can be regenerated and recycled.
