Spectrophotometric Determination of Hydrogen Peroxide by a Hydroquinone-Aniline System Catalyzed by Molybdate

Elnemma, Eman M. ( Korean Chemical Society , 2004 , Article)
In this system hydroquinone is oxidized to pbenzoquinone by H2O2. 2 aniline are added, in successive stages, to pbenzoquinone, to yield the disubstituted quinone as the final product. 20 The UV-VIS spectrum of the product ...
Synthesis and spectroscopic studies of metal complexes formed in the reaction of metal ions with urea at high temperature

Gaballa, Akmal S.; Teleb, Said M.; Nour, El-Metwally ( Korean Chemical Society , 2007 , Article)
Urea reacts with PtCl2, H2[PtCl6]·6H2O, H2[IrCl6] and Ni(CH3CO2)2 in aqueous solution at high temperature (60-80 °C) yielding [PtCl2(Urea)]·2H2O (1), (NH4)2[PtCl6] (2), (NH4)2[IrCl6]·H2O (3) and [Ni2(OH)2(NCO)2(H2O)2] (4) ...
