A set of research methods ($X$-ray phase, desorption, kinetic) was used to determine the state of the basic components ${K}_{2}{Pd}{Cl}_{4}$ and $Cu(NO_3)_2$ in the catalyst for the oxidation of carbon monoxide by oxygen. It was found that the palladium (II) and copper (II) initial compounds under the action of carbon fiber carrier change their state. Palladium is reduced to $X$-ray amorphous $Pd^0$, and copper (II) is in the form of a crystalline phase ${Cu}_2(OH)_3Cl$.

The regularities of Mo₂B catalyst activation in the epoxidation reaction of $\alpha$-ethylallyl ethyl acrylate with tert-butyl hydroperoxide have been studied. It has been shown that the catalyst activation process is described by the Avrami-Erofeev topokinetic equation and  includes two successive stages – the nucleation and formation of a new phase active in the epoxidation reaction. The forma- tion of epoxy only occurs in the presence of the activated form of the catalyst. The effective and topochemical process constants have been calculated.

The influence of the electrolysis parameters on the process of VT6 titanium alloy oxidizing in oxalic acid solutions is presented. It is shown that the nature of cell voltage-time curves for the alloy samples depends on the current density used. The interference-colored oxide films are formed on the surface of the alloy at the anodic current density above 0.5 A∙dm^-2. The maximal thickness and the oxide film color are determined by the cell voltage and do not depend on other electrolysis parameters.
