Abstract:
tert-butyl peroxypivalate was studied by gas chromatography, and some other peroxides were further studied. These thermolabile peroxides cannot be analyzed at high temperatures. At low temperatures, satisfactory chromatograms are not readily available because of the low vapor pressure. Therefore, the use of gas chromatography analysis must strictly control the relevant temperature. It is concluded that using PEG6000,DNP and Silicone SE-30 as the stationary phase, the carrier gas flow rate is set to 10 ~ 100mL/min, which has no effect on the decomposition of peroxide. Analysis conditions of tert-butyl peroxypivalate: Silicon SE-30 (stationary liquid),80 ℃ (Column temperature),10ml/min (carrier gas flow rate), naphthalene pentane (internal standard). The standard deviation was 0.84% and the recovery rate was 99.49%. Some peroxides that decompose immediately after evaporation cannot be detected by this method.
