Application range: About di-tert-butyl peroxide丨Shandong di-tert-butyl peroxide manufacturer:
Di-tert-butyl peroxideInvolved in many fields such as polymer synthesis, biochemical synthesis and metabolism, environmental pollution, food chemistry and cosmetics industry. The iodometric method commonly used for the analysis of di-tert-butyl peroxide is time-consuming and reagent-consuming. Recently, it has been reported that the gas chromatography internal standard method is used to determine peroxides, but the internal standard method is only suitable for the analysis of peroxides that are stable and easy to vaporize at low temperatures.
The peak area of the thermal decomposition product of peroxide has a linear relationship with the concentration of peroxide, but there are few specific studies in this area. Taking the relatively inactive di-tert-butyl peroxide (DTBP) as the research object, the composition of pyrolysis products was investigated, and the peak area of the main thermal decomposition product acetone and the amount of di-tert-butyl peroxide were found. Linear relationship. This relationship can be used to determine the peroxide content at the same vaporization temperature.
The precision of the thermal decomposition method is slightly worse than that of the internal standard method, but its application range is wider than that of the internal standard method, which is especially suitable for analysis that is easy to decompose and difficult to vaporize Peroxide. Although the column types used in qualitative analysis and quantitative analysis are different, the thermal decomposition products are completely the same.
