A safe analytical method for determining the concentration of degradation products in the solvent used for solvent extraction |
| abstract |
(57) [Abstract] [Purpose] TB used in solvent extraction process Provided is a safe analytical method for measuring the concentration of decomposition products, dibutylphosphoric acid and monobutylphosphoric acid, in a P-dodecane solvent. The chemical analysis method of the present invention does not use diazomethane, which is toxic and explosive, and thus a safer laboratory for routine analysis needed to monitor solvent extraction processes for production. Provide an intelligent method. According to the method of the present invention, mass-labeled deuterated dibutyl phosphate and monobutyl phosphate serving as internal standards are added to the solvent sample to be analyzed. After adding the silylating agent bistrimethylsilyltrifluoroacetamide, the sample is injected into a gas chromatograph / mass spectrometer and the ratio of the labeled internal standard to the naturally occurring substance is measured to obtain a quantitative analysis result. Is required. |
