Various approaches to flue gas desulfurization by low-grade manganese and high efficiency desulfurization in sintering enterprises were investigated, and the predominance areas of the Mn/Fe-S-O system were constructed in this paper. Additionally, the areas in different temperatures were established based on the thermodynamic properties achieved from manuals. From the view of thermodynamics, man...

The manuscript is an update to the earlier Science of Synthesis contribution describing methods for the synthesis and new applications of thiocarbonyl S-oxides (sulfines) and thiocarbonyl S-imides. In general, thiocarbonyl S-oxides are more stable and in many instances they can be isolated in substance. The in situ generated thiocarbonyl S-imides are efficient ‘sulfur transferring agents’ via t...

We described a solid-supported desulfurization procedure allowing easy access to the sequence analysis of oligonucleotide phosphorothioates. The described method is based upon selective removal of the 2-cyanoethyl phosphate protecting groups, followed by iodine-promoted desulfurization of the resulting phosphorothioate diesters. Automatic oxidation of oligonucleotide phosphorothioates, anchored...

We evaluated a new restricted access media (RAM) precolumn for direct analysis of drugs in plasma using a column switching HPLC system. The new RAM material was prepared by the modification of the external surface of porous silica with hydrophilic methylcellulose (MC), followed by modification of the internal surface with octadecylsilane (ODS). The external surface of the MC-immobilized ODS sil...
