	abstract = {<p>The production of ultra-low-sulfur diesel is an important worldwide demand. In this work a novel integrated method for desulfurization of diesel is proposed based on the combination of Bronsted acid catalyzed oxidation and the selective removal of the oxidized products using a molecularly imprinted polymer (MIP) produced in supercritical carbon dioxide (scCO2). The biphasic oxidation reaction of dibenzothiophene sulfone (DBT){,} as model substrate{,} and H2O2 as oxidant{,} was optimized by testing different acid catalysts{,} and also different phase transfer catalysts (PTC){,} including two different ionic liquids (ILs) trihexyl(tetradecyl)phosphoniumchloride [P6{,}6{,}6{,}14]Cl and Aliquat[registered sign]. The products of the efficient oxidation of DBT{,} dibenzothiophene sulfoxide (DBTSO) and dibenzothiophene sulfone (DBTSO2){,} were then selectively removed from real diesel using the MIP.</p>
