Thermal decomposition products of di-tert-butyl peroxide丨Shandong di-tert-butyl peroxide manufacturer
Organic peroxides cover many fields, such as polymer synthesis, biochemical synthesis and metabolism, environmental pollution, food chemistry and cosmetics industry. The iodine measurement method commonly used to analyze peroxides is time-consuming and requires a lot of reagents. The gas chromatography internal standard method is used to determine peroxides, but the internal standard method is only suitable for peroxides that are stable and easy to evaporate at low temperatures.
The peak area of peroxide pyrolysis products has a linear relationship with peroxide concentration, but there are few specific studies in this field. The relatively inactive di-tert-butyl peroxide (DTBP) was used as a research object to study the composition of pyrolysis products, and the peak area of acetone and the amount of di-tert-butyl peroxide were confirmed. Linear relationship. This relationship is used to determine the peroxide content at the same evaporation temperature. Compared with the internal standard method, the results are satisfactory. The precision of the pyrolysis method is slightly worse than that of the internal standard method, but its application range is wider than that of the internal standard method, making it particularly suitable for peroxide analysis, easy to decompose and not easy to vaporize. The types of chromatographic columns used for qualitative and quantitative analysis are different, but the pyrolysis products are exactly the same.
