Methyl orange, synthesis

MW-HT techniques can shorten the reaction time. For example, Ivanov et al. [38] synthesized ZnO nanocrystals in 10 min with the assistance of microwave hydro-thermal methods. Huang et al. [39] also demonstrated the use of microwave radiation in the hydrothermal synthesis of ZnO complex nanostructures. These nanocrystals showed high photocatalytic activity in a model reaction of Methyl Orange photodegradation. Li et al. [40] synthesized W03 nanorods in 20 min and showed high... 

Aldehyde synthesis. The reagent reacts with an alkyl- or arylmagnesium bromide to give a p-dimethylaminophenylcarbinol (1). This is easily cleaved by diazonium salts (diazotized sulfanilic acid was used because 3, Ar = p-H03SC6H4-, methyl orange is easy to eliminate). The products are the aldehyde (2) and an azobenzene...

Chen et al. reported in 2011 the synthesis of a twofold interpenetrated MOF Zn40(2,6-naphthalenedicarboxylate)3(DMF)i.5(H20)o.5 4DMF 7.5H20 (UTSA-38) and its catalytic activity for degrading methyl orange (MO) [45]. UTSA-38 has a band gap of 2.38 eV and exhibits catalytic activity under UV-visible light (Fig. 6).

Another attempted synthesis of Tc(III)-EDTA and Tc(III)-HEDTA complexes (EDTA ethylenediaminetetraacetic acid HEDTA A -(2-hydroxy-methyl)ethylenediamine-N,AT, iV -triacetic acid) was carried out using [Tc(tu)6]3+ as the starting complex [40]. Technetium-EDTA complexes have been synthesized by the direct reduction of pertechnetate with a suitable reduc-tant in the presence of excess EDTA [41-43]. On addition of EDTA to the Tc(tu) + solution, the intensity of the absorption spectrum decreased with time and the solution color changed from reddish orange to light brown. An electrophoretic analysis for the Tc(III)-EDTA complex showed that more than 70%...
