FIELD: measurement technology. SUBSTANCE: proposed technique for detection of maleimide in mixtures consists in photometry of their solutions on characteristic wave length, in determination of optic density, in recording of absorption spectra of components of mixture and in selection of organic solvent by comparison of absorption spectra of components of mixture with linear dependence of absorption maximum of maleimide on normalized parameter of polarity of solvent. Above-mentioned linear dependence is obtained by recording of absorption spectra of maleimide to be found in organic solvents distinguished by value of mentioned parameter. Then analyzed sample of mixture is dissolved in specified organic solvent and maleimide is detected. EFFECT: improved reproducibility of measurements. 1 dwg, 4 tbl
