В статье изучены физико-химические характеристики и фракционный состав нефтешламов. Поэтому нами были проведены лабораторные эксперименты по определению физико-химических свойств исходного сырья. В качестве сырья для получения антикоррозионных покрытий подобраны 2 образцы нефтяных шламов, которые...

В статье изложено результаты научно-исследовательских работ по влиянию депрессирующих примесей при сорбционном извлечении урана. Это доказывается тем, что сорбция сульфатных комплекса железа анионитом BO020 представляет определенный интерес, так как концентрация железа в растворе при сернокислотном ...

The results of the study on the physical and IR-spectral analysis of the fraction extracted from the composition of waste hexane – the fraction extracted by driving the secondary product under atmospheric pressure-were studied using the physical as well as the IR-spectral method. Research results...

The article describes the method of modifying sodium silicate with organic modifiers. As a result of modification with an organic modifier, the adhesion of sodium silicate increased by 2.5-3.02 times. This was explained by the dipole-dipole effect of the organic modifier.

This article provides information on the modification of collagen with modified aminoaldehyde. Information is also given about Van der Waals forces between these molecules. In order to assign different properties to oligomers, knowledge of their molecular properties is required. For this reason,...

The article analyzes the technology of obtaining amine absorbents on the basis of local raw materials for oil and gas processing enterprises. Ethylene oxide (EO) and methylamine (MA) are used as raw materials in the synthesis of MDEA absorbent. Ethylene oxide (EO) synthesis uses ethylene produced...

The process of chemical activation of mixtures of phosphorite and sulfur with a molar ratio (7:3) under the influence of potassium chloride, nitrate urea salts was studied. In activated phosphorite samples, as a result of the decomposition of fluorapatite and calcite minerals, the formation of...

The article describes the process of nickel extraction from the used waste of the GIAP-8 catalyst in the form of nickel nitrate, in which it not only does not affect the environmental environment, but is also a cost-effective solution for the production of nickel catalysts. The obtained catalysts...

This article explains the creation of a scientific basis for a convenient, cost-effective technology that allows the production of plasticized secondary polymer composite materials (PCM) by repeatedly recycling polymer waste that pollutes the environment. The practical significance of the research...

In recent years, furan derivatives have become increasingly important in the creation of materials and compositions with the desired properties. The traditional direction of furfural processing is the extraction of furfuryl alcohol obtained as a result of its condensation and resins with various...

In this study, this titanosilicate ceramic product (Sphene, CaTiSiO5) was prepared using co-precipitation, sol-gel and solution incineration methods. All of these processes produced amorphous powders in the initial phase, which were found to crystallize on further calcination and form co-crystals...

The possibility of cobalt sorption of by anion exchangers from hydrochloric acid solutions in the presence of nickel was evaluated in the paper. The highest value of sorption capacity was observed in the gel anion exchange resin with pyridinium functional groups (Axionit VPA G.2.4) and the...

Production of anti-corrosion inhibitors based on local raw materials containing nitrogen, sulfur, phosphorus, soluble in gas condensates, and the practical use of products that inhibit corrosion processes in metal pipes. At the same time, research in the field of multifunctional organic composites...

Currently, work is underway around the world to develop new multifunctional compositions that inhibit corrosion, aimed at obtaining environmentally friendly corrosion inhibitors from secondary industrial products and the efficiency of using phosphorus-, sulfur-, and nitrogen-containing corrosion...

The effect of various factors (temperature, volume velocity, acetylene:water ratio, catalyst composition, etc.) on the product yield and process selectivity in the catalytic hydration reaction of acetylene was studied. The surface area of the catalytic system was determined by the Ssol=BET method,...

Acetone and vinyl acetate take the leading place among the oxygenated compounds produced in the world today in petrochemical and basic organic synthesis industries. Today, the annual need for acetone in the world is 2 million tons, the annual need for vinyl acetate is 10 million tons, and in our...

The physicochemical properties of serobite have been studied. The composition of serobite has been analyzed.It has been established that bitumen contains (sulfur, oxygen, nitrogen). It has been established that the bitumen composition has a complex structure, and the properties of the serum have...

This article presents a new MEA for purifying natural gas from acidic components monoethanolamine; DEA – diethanolamine; MDEA – methyldiethanolamine; PEGDME – polyethylene glycol dimethyl ether; The results of a study of absorbent compositions prepared on the basis of PEGMME polyethylene glycol...

The newly composite corrosion inhibitors have been synthesized from monoethanolamine, methyl methacrylate and phosphoric acid and their inhibition efficiency were studied. In this case, the mole ratio of the initial substances was maintained 1:2:2 respectively and the temperature was also remained...
