• Properties of di-tert-butyl peroxide丨Shandong di-tert-butyl peroxide manufacturer

    The production process of DTBP (initiator A) is carried out intermittently. The quality of wastewater, the concentration of organic matter, pH, salt content, BOD/CDO value, etc. vary with the production scale and time, and the peak and valley values vary greatly. DTBP is thermally unstable and easily decomposes quickly, causing an explosion. DTBP dissolved in wastewater will also rapidly decompose at high temperatures, which also brings safety hazards. In the production process, a large amount of waste acid liquid will be produced, and a large amount of alkaline washing waste liquid will be produced in the product purification process. The concentration of pollutants in the wastewater is high, the composition is complex, and the B/C value is very low, and biochemical treatment cannot be carried out. Direct discharge of this kind of wastewater into rivers will seriously pollute water bodies. Properties of di-tert-butyl peroxide丨Shandong di-tert-butyl peroxide manufacturer

  • 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.

  • The relationship between the decomposition temperature of di-tert-butyl peroxide and the amount of decomposition丨Shandong di-tert-butyl peroxide manufacturer

     The relationship between the decomposition temperature of di-tert-butyl peroxide and the amount of decomposition was investigated by gas chromatography, and the composition of the decomposition products of di-tert-butyl peroxide was studied. The experiment found that there is a linear relationship between the peak area of the main thermal decomposition product and the amount of di-tert-butyl peroxide in the range of 22.91~114.93μg. It has good precision to determine the peroxide sample of unknown concentration.

  • Di-tert-butyl peroxide is a high-temperature active peroxide丨Shandong di-tert-butyl peroxide manufacturer

    Di-tert-butyl peroxide is used as a fuel additive to test the starting performance of a compression ignition natural gas (LPG) engine with extremely low cetane number. The results show that di-tert-butyl peroxide can make the cetane number reach 60, thus realizing the engine start at room temperature. Analyze the volatility index and combustion characteristic index of biodiesel, analyze the influence of different additions of di-tert-butyl peroxide on the volatility and combustion characteristics of biodiesel, and provide a theoretical basis for improving the combustion process and emissions of biodiesel. The volatilization of liquid substances is mainly because liquid substances absorb heat, overcome intermolecular forces, and form gaseous substances. Di-tert-butyl peroxide is a high-temperature active peroxide, which is relatively stable to heat. At a temperature of 290°C, a decomposition reaction is initiated and volatile substances are generated, resulting in an increase in weight loss rate. The volatilization and pyrolysis process of biodiesel can be evaluated by the volatilization index. The volatility of biodiesel has a great influence on the formation, ignition, combustion and emissions of the mixture. The better the volatility, the more conducive to the formation of a homogeneous mixture, which promotes the ignition of the fuel. The fuel volatilization index can be used to evaluate the ignition characteristics of the fuel.

    The transportation of tert-butyl hydrogen peroxide: the transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment during transportation. Parallel transportation with reducing agents, strong acids, flammable or combustible substances, active metal powders and other substances is strictly prohibited. Speed should be controlled to avoid bumps and shocks. Transport in the morning and evening in summer to prevent sunlight. Road transportation should follow the prescribed routes and stop in residential areas and densely populated areas. Before and after loading and unloading, transport vehicles should be thoroughly cleaned, and it is strictly forbidden to mix organic matter, combustibles and other impurities.
