Nitric Acid Content

Kyzylkum phosphate rock was studied with a nitric acid content of 50 and 75 and 100%, as well as in fertilizers obtained from the ratio of R2O5: K2O = 1:1. The gyroscopic points of the fertilizer size of 2-3 mm were determined at 250 ° C by the desiccator method of N.Ye. Pestov. The points of hygroscopicity of fertilizer samples with an initial moisture content of 1.0% were No. 1 - 46.5%, No. 2 - 38.0% and No. 3 - 32.4%.

Azo Derivatives

The nitration of N, N′-disubstituted hydrazines (RNH–NHR) by means of nitric acid – acetic anhydride mixtures has been found to yield, in most cases, the azo derivatives (RN = NR). For example, when R = CH3, (CH3)2(CN)C, CH3CO, or C2H5OCO, azo derivatives were formed. When R = HCO, nitrogen, carbon dioxide, and nitrogen oxides were evolved. An exception was observed with N, N′-dibenzoylhydrazine which, under the same conditions, yielded the N, N′-dinitro-N, N′-dibenzoylhydrazine.

AbstractIn recent years, Supercritical Fluid Extraction (SFE) technique has been widely used for the extraction of metal ions. In the present study, extraction of uranium from nitric acid medium was investigated using supercritical carbon dioxide (Sc-CO
