Effectiveness of Fenton Reagent in Oxidation Process of Methyl Violet Dye

Decoloration methyl violet dye by Fenton reagent was investigated spectrophotometrically. Reagents concentration, pH value, and metal ion were varied. It was shown that substrate oxidation rate depends non-linearly on dye concentration, Fen+, H2O2, and pH value. The composition of the reaction mixture providing maximum oxidation rate and MV conversion is proposed.

Influence of surface-active additieves on processes of alkylaromatic catalytic oxidation

The process of ethylbenzene oxidation in the presence of catalytic systems, that consists fromsalt of variable valence metal and organic additives, was explored. Suggestion about the influence mechanism of additives on the ethylbenzene oxidation process were made.

Single Stage Acrylic Acid Obtaining based on Methanol and Acetic Acid

The new complex oxide acid type catalysts were developed and their performance in the process of aldol condensation of acetic acid with formaldehyde to acrylic acid was studied. The optimum conditions of the process were determined. It was established that these catalysts are effective in the process of methanol to formaldehyde oxidation, and also in the process of single stage acrylic acid obtaining from acetic acid and methanol in the presence of air.
