Deep Oxidative Desulfurization of Fuels in the Presence of Brönsted Acidic Polyoxometalate-Based Ionic Liquids.

Argam Akopyan et al.

Molecules (Basel, Switzerland), 25(3) (2020-01-30)

Polyoxometalate-based ionic liquid hybrid materials with a pyridinium cation, containing Brönsted acid sites, were synthesized and used as catalysts for the oxidation of model and real diesel fuels. Keggin-type polyoxometalates with the formulae [PMo12O40]3-, [PVMo11O40]4-, [PV2Mo10O40]4-, [PW12O40]3- were used as

Substitution reactions of 4-methyldibenzothiophene.

Validation of a simultaneous method for determining polycyclic aromatic compounds and alkylated isomers in biota.

Ifeoluwa Idowu et al.

Rapid communications in mass spectrometry : RCM, 32(3), 277-287 (2017-11-28)

There is a need for a validated method to improve detection limits and simultaneously quantify polycyclic aromatic compounds (PACs, both parent and alkylated homologues) in biota by gas chromatography/tandem mass spectrometry because of their environmental significance. The validation of the

Improving the Catalytic Performance of Keggin [PW12O40]3- for Oxidative Desulfurization: Ionic Liquids versus SBA-15 Composite.

Susana O Ribeiro et al.

Materials (Basel, Switzerland), 11(7) (2018-07-14)

Different methodologies were used to increase the oxidative desulfurization efficiency of the Keggin phosphotungstate [PW12O40]3- (PW12). One possibility was to replace the acid proton by three different ionic liquid cations, forming the novel hybrid polyoxometalates: [BMIM]₃PW12 (BMIM as 1-butyl-3-methylimidazolium), [BPy]₃PW12

Solvent-Free Desulfurization System to Produce Low-Sulfur Diesel Using Hybrid Monovacant Keggin-Type Catalyst.

Fátima Mirante et al.

Molecules (Basel, Switzerland), 25(21) (2020-10-31)

Two quaternary ammonium catalysts based on the monovacant polyoxotungstate ([PW11O39]7-, abbreviated as PW11) were prepared and characterized. The desulfurization performances of the PW11-based hybrids (of tetrabutylammonium and trimethyloctadecylammonium, abbreviated as TBA[PW11] and ODA[PW11], respectively), the corresponding potassium salt (K7PW11O39, abbreviated

Hydrodesulfurization of 4-Methyldibenzothiophene and 4,6-dimethyldibenzothiophene on a CoMo/Al₂O₃ catalyst: Reaction network and kinetics.
