Organophosphate compounds are widely used in industrial hydrometallurgical processes as extractants and complexones of non-ferrous, noble, rare-earth metals and transuranic elements. Among these compounds, organic phosphates occupy a special place, as they allow for the extraction processes with good selectivity and efficiency. Therefore, the search and development of new uranium effective extractants is an important task for the development of modern hydrometallurgical processes. For this functional phosphate containing a cyano group, one should expect a synergistic effect of the extraction properties of the phosphates themselves, as well as of the known extractants – contribute to an increase in its incombustibility. Thus, the use of this extractant in the production of the extraction of uranium from uranium-containing nitric acid or sulfuric acid solutions was 20.7% and 18.7%; the content of uranium in the extractant was 63.9 g/dm3 and 49. 7 g/dm3, resp. Pos. results were also obtained when studying the synergistic properties of the new extractant and the traditional – bis(2-ethylhexyl) phosphate. Using a mixture of these extractants (their weight ratio was 1:1.2) allows you to extract 57% of uranium from the uranium sulfate solution The use of bis(2,2,2-trifluoroethyl)(2-cyanoethyl) phosphate as a new extractant makes it possible to extract up to 20.7% of uranium from technol. nitrate or sulfate of uranium-containing solutions In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Application of 628-13-7).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Application of 628-13-7
