Green oxidation with aqueous hydrogen peroxide.

Aqueous H2O2 is an ideal oxidant, when coupled with a tungstate complex and a quaternary ammonium hydrogensulfate as an acidic phase-transfer catalyst. It oxidizes alcohols, olefins, and sulfides under organic solvent- and halide-free conditions in an economically, technically, and environmentally satisfying manner.

Selective Aerobic Oxidation of Alcohols by Non-metallic Oxidation Systems --- Towards Green Chemistry

Introduction Selective oxidation of organic compounds is one of the major challenges facing the chemical industry. The selective transformation of alcohols to aldehydes and ketones, in particular, is among the most important synthetic operations in organic chemistry. Numerous methods have been reported and widely used for this purpose utilizing various organic and inorganic oxidants, for exampl...

Designing green oxidation catalysts for purifying environmental waters.

We describe the synthesis, characterization, aqueous behavior, and catalytic activity of a new generation of Fe(III)-TAML (tetraamido macrocycle ligand) activators of peroxides (2), variants of [Fe{(OC)(2)(o,o'-NC(6)H(4)NCO)(2)CMe(2)}(OH(2))(-)] (2d), which have been designed to be especially suitable for purifying water of recalcitrant oxidizable pollutants. Activation of H(2)O(2) by 2 (k(I)) ...

Electro oxidation of Malachite Green and Modeling Using ANN

This study involves the electro-oxidation of malachite green, a triphenyl methane dye, extensively used in industries and aquaculture, and later banned in most developed countries because of its potential carcinogenicity, mutagenicity and teratogenicity in mammals. The study is conducted in a batch electro-chemical reactor using the catalytic anode (made of noble oxide coated, RuOx-TiOx, titani...
