| Resumen |
For sampling of the mixture, silica gel coated with diethylamine was used. Since isocyanate is highly reactive, it must be rapidly converted into a stable derivative. This was achieved by reaction with diethylamine. After desorption of the mixture, compounds are separated by high-performance liquid chromatography. Spectrophotometric detection was used for determination of the mixture components. |
