A two-step procedure for preparing N-nitrosodimethylamine by direct nitrosation of aqueous solutions of dialkylamines with dinitrogen dioxide was suggested. The first step involves preparation of dialkylammonium nitrite, and in the second step, on heating to 70–90°С in a weakly acidic solution, it transforms into N-nitrosodialkylamine. The yield of N-nitrosodialkylamines is 95–98% based on the converted dialkylamine. A low-waste process for N-nitrosodimethylamine production was developed.

A two-step procedure for utilization of cellulose nitrate waste accumulated at industrial enterprises of the Russian Federation was suggested and experimentally checked. The procedure involves hydrolysis of cellulose nitrate in alkaline medium and incineration of hydrolysis products. The best reagents for complete hydrolysis of cellulose nitrate are aqueous solutions of sodium hydroxide and sodium carbonate. As demonstrated by thermal analysis and thermodynamic calculations, incineration of cellulose nitrate base hydrolysis products can be performed without using hydrocarbon fuel.

Benzylidene condensation of R-tetrazol-1-ylphenylamines with 4-fluorobenzaldehyde was studied. The correlation between the logarithm of the rate constant of the condensation of 4-fluorobenzaldehyde with R-tetrazol-1-ylphenylamines and their pKBH+ values was found. The reaction constant ρ in the Hammett equation was determined.

An experimental study of the kinetic stage of combustion fumes of organochlorine wastes. We obtained the data on the normal speed of propagation of the flame, and other parameters of the flame front. Also we found an effective constant of the reaction rate and determined requirements for reactors of a high-temperature oxidation of organochlorine waste.

Descriptive kinetics of synthesis of tetraacetylethylenediamine by acylation of diacetylethylenediamine with acetic acid anhydride was examined. The apparent rate constants of the process were obtained, and a mathematical model adequately describing the process was constructed.

Nucleofilic reaction of a series of α-bromocarboxylic acids with hydrazine and dimethylhydrazine is studied. High reactivity of α-bromocarboxylic acids is revealed and a series of α-hydrazinoarboxylic acids and N-(1-carboxyalkyl)-N,N-dimethylhydrazinium bromides are synthesized.

Catalytic properties of carbon materials Sibunit (commercial samples) and ceria-promoted precious metals (Ru, Pt, Pd) supported on carbon were studied in the processes of catalytic wet air oxidation (CWAO) of aniline and phenol at elevated pressures and temperatures (T =433–473 K, PO2 = 0.3–1.0 MPa). It was found that the activity increases when the catalyst is pretreated with hydrogen peroxide. An efficiency of Ru–CeO2/Sibunit catalyst with a low ruthenium content (~0.6 Ru) for deep cleaning of polluted waters is demonstrated.

The reactions of 1,1-dimethylhydrazine, methylhydrazine, and hydrazine hydrate with 5-aryl-2-chloromethyl-1,3,4-oxadiazoles were studied. The structures and compositions of the final products were confirmed by 1H NMR spectroscopy and elemental analysis.

The reactions of methylhydrazine and hydrazine hydrate with chlorinated pyridazines and pyridazones were studied.

Synthesis of biheterocyclic thiazole-amonooxadiazoles, the potential biologically active compounds is developed. Regularities of transformations and physico-chemical characteristics of intermediates and final compounds are revealed.

Acetylation of 5-aryltetrazoles, 5-(5-methyl-2-furyl)tetrazole, and 5-(1,5-dimethyl-2-pyrrolyl)tetrazole with chloroacetyl chloride was studied.

Among various methods of toxic waste treatment the most universal are methods of high-temperature (thermal) mineralization (HTM). The essence of the HTM method is in the thermal action on wastes, which results in oxidation (combustion), gasification or recovery with formation of inorganic (mineral) substances. Usually, toxicity decreases or full detoxification takes place. If necessary, the gaseous products of high-temperature mineralization are subjected to additional cleaning.

Bromination of isovaleric acid with bromine in the polyphosphoric acid mediumis was studied, regularities of the process including influence of the polyphosphoric acid composition were revealed, the process was shown technologically attractive for the organization of industrial manufacturing of α-bromoisovaleric acid.
