Synthesis of octochlorosubstituted cobalt(II) and copper(II) complexes with phthalocyanine

Fig.3 - Combined spectrum of CuPcCl8 and CoPcCl8 compounds in the range from 500 to 1800 cm-1 A detailed assignment of the bands of valence and deformation vibrations in the IR spectra of unsubstituted phthalocyanine complexes of cobalt(II), copper( II) obtained by solid phase synthesis was done by us in (fig.3) [5]. The IR spectra of chlorine-substituted metallophthalocyanine complexes of the same metals in the same oxidation states obtained in the presence of 1,2,4-trichlorobenzene have slight differences, since the IR spectra of substituted metallophthalocyanines consist of bands attached to the phthalocyanine part of the molecule and bonds of chloride ions. Due to the fact that these bands partially overlap, the interpretation of the spectra was carried out on the basis of a comparative analysis with the spectra of chloro-substituted methylphthalocyanines and their unsubstituted metallophthalocyanines.

In the spectra of synthesized compounds in the region of 1650-1500 cm-1 there are bands of valence vibrations of C-C-benzene rings, the interpretation of spectra in the region of 1400-750 cm-1 is complicated due to the overlap of bands that related to both the vibrations of phthalcyanine fragments and fragments of chloride ions.

Landscape forming factors of the Karkaraly low mountains ___________________________________________________________

Geosystems of the Karkaraly Low Mountains are located in the eastern part of the Kazakh Highlands in the Karkaraly District of the Karaganda Region. The area under study is located almost entirely in the dry steppe subzone of the steppe landscape-climate zone. The first geobotanical studies of the geosystems of the Karkaraly Mountains were carried out by A.Ya.

In the eastern part of the Highlands, much attention was paid to the study of the forest vegetation of the low mountains. With regard to the magmatic forms of the Upper Paleozoic, the modern terrain is directly inherited. The key areas were selected based on the geographical and indicative localization of the mapped ecosystems.

1 is located near the middle part of the Karkaralinka River, northeast of the town of Karkaraly. There are trees (elm, birch) in combination with bushes (hips, currants) at the foot of the hills. 4 is located on the territory of the middle part of the Zharly River near the village of Karbushevka.

The soil pH values ​​of all key areas can be correlated as alkaline. During the reconstruction of the Karagaily Mining and Processing Plant, emissions from 46 sources of pollution (main activities of the concentrator) were taken into account.

Cезонная динамика биологической продуктивности основных ассоциаций степей Западного Казахстана

M. Ataeva

The work presents the results of the author's own research on the study of the seasonal dynamics of the biological productivity of the main associations of the complex steppes of Western Kazakhstan. Based on the results of the research, recommendations have been developed for the conservation of steppe ecosystems and the rational use of pastures during the growing season, including in years with different hydrothermal regimes. The biological productivity of vegetation, combined with climatic factors, has for centuries ensured the fertility of the soil of the steppe zone, the main breadbasket of agriculture and livestock farming.

Practical frontal plowing of the Kazakh steppe, more than 70%, contributed to the transformation of steppe vegetation on large areas.

Особенности агрометеорологических условий в Туркестанской области

При коэффициенте вариации менее 17% ряд считается абсолютно однородным, при 17-33% - достаточно однородным, при 34-40% - недостаточно однородным, более 40% - неоднородным. Вегетационный период 2021 г. характеризовался очень высокими температурами воздуха (выше нормы), а в 2022 г. фоновая летняя температура также была выше нормы. Например, суточная максимальная температура воздуха выше 32°С неблагоприятна для культур с умеренным теплом (ранние яровые культуры), выше 37°С неблагоприятна для теплолюбивых культур.

В 2021 году количество теплых дней для среднетепловых культур составило от 59 до 86 дней, для теплолюбивых – от 13 до 41 дня. Коэффициенты вариации многолетних рядов коэффициента влажности К в пустынной зоне - 30 %, в горно-пустынной зоне - 26 %, в горно-полупустынной зоне - 26. Годы с удовлетворительными погодными условиями имеют повторяемость. в горно-полупустынной зоне - 20% (2 года из 10), в горно-пустынной зоне - 10% (1 год из 10).

The trends of changes in agrometeorological indicators in the Turkestan region for the period from 1991 to 2022 are analyzed. There is a tendency to increase the amounts of air temperature for the growing season, a tendency to decrease the amounts of precipitation for the growing season, a tendency to decrease the values ​​of the moisture coefficient K and the drought index HTC. Such conditions mean an increase in the heat supply of the growing season, an increase in the number of hot days, a decrease in humidity and an increase in the dryness of the growing season.

Years with satisfactory weather conditions have a repeatability of 20% in the mountainous semi-desert zone and 10% in the mountainous desert zone. Years with adverse weather conditions have a repeatability of 100% in the desert zone, 90% in the mountainous desert zone, and 50% in the mountainous semi-desert zone.
