METHOD OF DETERMINATION OF THE COMPOSITION OF THE EXTRACTING MIXTURE OF TRIBUTYLPHOSPHATE AND THE SOLVENT Russian patent published in 2007 - IPC G01N9/36 

FIELD: chemical industry; methods of determination of the composition of the extraction mixture of tributylphosphate and the solvent.

SUBSTANCE: the invention is pertaining to the chemical technology and may be used for determination of the value of the volumetric share of tributylphosphate in the extracting mixture. The technical result of the invention is reduction of the technological and economical expenditures dealt with the elaboration and correction of the production process parameters. The idea of the invention consists that determination of the composition of the extraction mixture of tributylphosphate and the solvent provides for addition of the solvate-forming compound, preparation and measurement of the characteristic of the calibration extracting mixtures of the different composition and computation of the composition of the extraction mixture according to the calibration dependence. As the measured characteristic use the increase of density of the extraction mixture after realization of extraction of solvate-forming compound in the saturation mode of the extraction mixture.

EFFECT: the invention ensures reduction of the technological and economical expenditures dealt with the elaboration and correction of the production process parameters.
