Developing processes with minimal environmental impact is essential for the production of the important intermediates and final products. Present study explores the green and low-cost synthesis of new halogenated derivatives of 1-aminoanthraquinone under catalyst free conditions at room temperature. These derivatives find wide practical application due to their unique properties. Numerous studies on the preparation of new derivatives have been devoted to the development of industrial dyes and pigments. These compo...

The sulfide containing wastes stocked in the Ur dumps were studied in this paper. The Novo-Ursky copper-pyrite deposit, containing the polymetallic ores, was discovered in 1932 as part of the Ursky ore field, Kemerovo region. During the day, the parameters of each of the dumps change: temperature, humidity of the upper layer, geoelectric parameters, concentrations of emitted substances (gases, vapor with volatile compounds of chemical elements). This article discusses these variables in terms of an integrated appr...

In water scarce districts of the Akmola region the areas were revealed, perspective for carrying out exploration on underground waters and the card of forecast resources of underground waters of the Akmola region of scale 1:1 000 000 is constituted. As the main methods of researches are used: decryption of satellite images using cloudless fragments of space pictures of Landsat-8 from 2013 for 2016. In case of decryption of satellite images of the Akmola region comic pictures of the territory on 6 sites are process...
