Effect of three alkaline impurities on the pressure of 1,2, 4-triazole pyrolysis gas

Abstract

1,2,4-triazole is now widely used in the production of pesticides and medicine, and progress has been made in the application of materials. The structural characteristics of 1,2,4-triazole with high nitrogen content will cause it to the release of a large amount of gas when it occurs pyrolysis, which may have a certain impact on industrial production safety. In the industrial process, there will be some other impurities mixed into it, so the influence of these impurities on the 1,2,4-triazole pyrolysis gas is worth exploring. In this study, the adiabatic acceleration calorimeter was used to simulate the adiabatic conditions to study the pressure value of the gas generated by the pyrolysis of 1,2,4-triazole itself, and the influence of the addition of three basic impurities on the overall pyrolysis pressure value. Experiments show that these three impurities can affect the pressure value of pyrolysis gas in different degrees. The results can provide reference for the loss prevention and control of 1,2,4-triazole in industrial production.
