“…Accelerating rate calorimeter (ARC) has been used widely for estimating the explosion characteristics of explosives and other hazardous materials [30][31][32][33][34][35][36][37][38][39][40]. In this study, ARC supplied by NETZSCH Company using an 8.5 mL Hastelloy bomb with a thermocouple clip located on the bottom of the bomb is used.…”

The thermal decomposition of dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) with three different particle sizes were studied under adiabatic condition by using accelerating rate calorimeter (ARC). The adiabatic experiment revealed that TKX‐50 had two decomposition stages. Based on the experimental results, the decomposition parameters including the thermal data and pressure data of three kinds of TKX‐50 were used as the hazard assessment indicators. The results revealed that the decomposition of TKX‐50 nanoparticles was the mildest among all of the samples in the first decomposition stage. In addition, the SADT of three kinds of TKX‐50 with different sizes were predicted when stored in the wooden cylinder, and the results showed that TKX‐50 milliparticles exhibited the best thermal stability.

“…Nevertheless, increasing the aniline supply represents a potential risk since the synthesis route currently used by 85% (Wang et al, 2019) of the aniline production companies worldwide (nitration of benzene) is highly hazardous, as it involves the use of strong acids in high concentrations, such as sulfuric acid and nitric acid, and the production of unstable and explosive byproducts such as dinitrophenol, picric acid, dinitrobenzene and nitrobenzene (Badeen et al, 2011;Cuypers et al, 2018;Kletz, 2009;Trebilcock and Dharmavaram, 2013). These conditions have caused multiple fatal accidents throughout history.…”

The purpose of this research is to demonstrate through a techno-economic assessment that aniline can be industrially produced using a profitable and inherently safer process than the ones currently employed. The aniline production process was designed using process simulation software. From this, the mass and energy balances were determined, the equipment sizing was performed and the net present value (NPV) was calculated to be USD 93.5 million. Additionally, a heat integration analysis was carried out in order to improve process profitability, obtaining a new NPV of USD 97.5 million. The economic sensitivity analysis showed that the process could withstand fixed capital investment changes of up to +89%, weighted average cost of capital changes between 16–24% and a decrease in cyclohexylamine demand of up to 44%. The conceptual design is still profitable when aniline price is varied in a range of 1224–1840 $/t and phenol cost in a range of 815–1178 $/t.

Beyond Dinitrophenol Interaction with Tryptophan-Based Compounds

Abstract:The effects of 2,4-dinitrophenol (2,4-DNP) on the spectroscopic parameters (UV-Vis or FT-IR absorbance) or fluorescence emission of tryptophan and glycyl-tryptophan were studied. A quenching phenomenon of fluorescence was observed, attributed to interactions between the indole ring of the fluorophore and the aromatic ring of the quencher. The analysis of fluorescence spectra confirms that the quenching is dictated by 2,4-DNP concentration and pH. A combined mechanism of static and dynamic quenching was detected. The quenching phenomenon observed in this work could be employed to explain the mechanism of action of such compounds on large fluorescent peptides or proteins.
