Safety evaluation of chemical reactions is very significant before industrial applications are conducted. A lot of thermal hazards are generated in the synthesis of 3,4-bis(4-nitrofurazan-3-yl)furoxan (DNTF) because of the strong exothermicity of the oxidation reaction, unstable hydrogen peroxide, and interactions between the materials. In this article, systematic parameters regarding the safe synthesis of DNTF were studied, including the preparation stage of reaction solution and the oxidation reaction step. A Calvet microcalorimeter and an RC1mx reaction calorimeter were employed for process safety research. Differential scanning calorimetry and adiabatic accelerating rate calorimetry were used to investigate the thermal stabilities of the materials and their thermal hazards. After screening of the thermal stabilities of the materials in the two stages, hazardous materials were identified, and their thermal safety parameters were obtained. Finally, two evaluation methods were applied to evaluate the hazard levels of the preparation process and the oxidation reaction process in the synthesis of DNTF on the basis of thermal safety parameters. This study provides critical safety technical guidance for the DNTF synthesis process and safety design.

“…All heat released from the test sample goes to energy accumulation in the sample and cell, which is the working principle of the ARC setup. It has become an indispensable and strong tool in the field of process safety in recent years. − Using the ARC, Brown et al revealed the destructive thermal hazard of a reaction involving propargyl alcohol and potassium hydroxide, and Sheng et al studied the di- tert -butyl peroxide-toluene system which has a high self-heat rate. Through the combination of the reaction calorimeter and ARC, researchers have great chances to comprehensively and thoroughly understand the kinetics and thermal properties of a chemical reaction.…”

From the safety point of view, thermal risk analysis in the process industry is generally of significant importance and often requires calorimetric and kinetic modeling. These techniques were applied for the first time in the study of a highly exothermic condensation reaction, which is used to prepare 2,2′-methylene-bis(4,6-di-tert-butylphenol) phosphate chloride, a quite important intermediate in the fine chemical industry. The thermodynamics properties such as reaction heat, adiabatic temperature rise, and specific heat capacity of the synthesis reaction were experimentally investigated under isothermal conditions using a robust process analytical technology-based in-line reaction calorimeter EasyMax. A kinetic correlation model was developed based on the calorimetry and subsequently verified. This exhibited a much more efficient and convenient way to study the reaction kinetics compared with the conventional off-line determination of molar concentration or conversion. An accelerating rate calorimeter was used to reveal the thermal controllability of the reaction system as well as some potential hazards. The thermal and kinetic parameters lay a solid foundation for the design and safe operation of reactors. The related methods are also anticipated to be extended to a wide range of similar highly exothermic reactions.
