Abstract

Byla vypracována metoda pro kvantitativní stanovení vedlejších produktů v tetrabromdianu po převedení na trimethyl- silyletftery. Analýza se provádí například na náplňové ohromatografické koloně délky 2,40 m a vnitřním průměru 2 mm při teplotě 250 °C a průtoku nosného plynu 22 ml/min. Kolona je smočena silikonem na bílém nosiči. Za podmínek analýzy je možno stanovit chlor- a bromderiváty fenolu, p-isopropenvlfenolu a dianu.A method was developed for the quantitative determination of by-products in tetrabromide after conversion to trimethylsilylethers. The analysis is carried out, for example, on a packed chromatography column with a length of 2.40 m and an internal diameter of 2 mm at a temperature of 250 ° C and a carrier gas flow of 22 ml / min. The column is wetted with silicone on a white support. Under the conditions of the analysis, the chloro- and bromo derivatives of phenol, p-isopropylene phenol and dian can be determined.
