In the present work, a novel method for the treatment of wastewater containing an azo dye, acid red-14 by hexacyanoferrate [HCF(III)] in presence of iridium nanoclusters has been proposed. The effect of some important operational parameters such as pH, temperature and catalyst concentration (iridium nano) has been investigated by kinetic spectrophotometric method at λmax 515 nm of the reaction mixture. The results reveal that degradation kinetics of acid red-14 follows first order kinetic model with respect to [HCF(III)], [acid red-14] and Ir nano concentration. Iridium nanoclusters were recovered with the help of centrifugation and reused for three consecutive cycles. Thermodynamic parameters Ea, ΔS#, ΔF#, ΔH# and 'A' have been calculated by studying the reaction rate in the range of temperatures 40 to 55 °C. The formation of degradation products was characterized by chromatographic and spectroscopic techniques after the extraction with ethyl acetate. 1-Hydroxy-2-amino naphthalene and naphthalene sodium sulphate were identified as major degradation products. The results can provide fundamental knowledge for the treatment of wastewater containing acid red-14/other azo dyes.

(equation presented) Regio-and chemoselective reduction of nitroarenes and carbonyl compounds and reductive cleavage of azo compounds, including bulkier molecules, was achieved by the catalytic transfer hydrogenation method (CTH) using a novel nickel-containing mesoporous silicate (NiMCM-41) molecular sieve catalyst. In addition, the catalyst was also found to behave as a truly heterogeneous catalyst as the yield was practically unaffected.

In a method for preparing an adduct of (A) a butadiene lower polymer or butadiene lower copolymer and (B) a α,β-ethylenically unsaturated dicarboxylic acid compound, said method is characterized in that said (A) and (B) are caused to react in the presence of one or more compounds selected from (C) p-phenylenediamine derivatives, catechol derivatives, pyrogallol derivatives, N-nitrosamines, quinoline derivatives and naphthol derivatives, thus serious increase of the viscosity of said adduct in the addition reaction can be prevented.
