STUDY BY MASS SPECTROMETRY OF SOLUTIONS OF [HYDROXY(TOSYLOXY)IODO]BENZENE: PROPOSED DISPROPORTIONATION MECHANISMS. Solutions of [hydroxy(tosyloxy)iodo]benzene (HTIB or Koser's reagent) in acetonitrile were analyzed using ...

Ferrierite zeolites have been prepared, characterized and evaluated in toluene disproportionation. The materials were synthesized using a hydrothermal method. A passivation process (chemical liquid deposition, CLD) was ...

Disproportionation reactions take place in solution of (diacetoxyiodo)benzene (DIB) in acetonitrile in the presence of water, giving iodine(V) and iodine(l) species. This redox reaction is accelerated by the presence of ...

Experimental evidence for a dismutation equilibrium in the mixed-valence (MV) [Mn+ -M(n+1)+] system type has been elusive and its existence can be established only when the oxidation-reduction processes involved are ...

Solutions of [hydroxy(tosyloxy)iodo]benzene (HTIB or Koser's reagent) in acetonitrile were analyzed using high resolution electrospray ionization mass spectrometry (ESI-MS) and electrospray ionization tandem mass spectrometry ...

Iron oxides are important compounds in science and technology. Due to their structural, electronic, magnetic and catalytic properties they are useful for several applications. Among them, sulfated hematite (SO4 2- /αFe2O3) ...

In this paper zeolite Beta was synthesized and characterized by XRD, ATG, ATD, XRF and SEM. Subsequently various modifications were made using a surface passivation process in liquid phase with tetraethylorthosilicate ...
