Propylene Glycol Alginate Sodium Sulfate (PSS) is widely produced and used in medicine as a marine drug for treating hyperlipidemia. During the sulfonation synthesis of PSS, the sulfonation of chlorosulfonic acid is exothermic. At high temperatures, the process can easily produce a large amount of ammonium sulfate. Ammonium sulfate adheres to PSS in crystal and participates in the sulfonation reaction. In this study, the sulfonation process of commercial PSS was reproduced in the laboratory using chlorosulfonic acid and formamide. We used differential scanning calorimetry and thermogravimetric analyzer to examine the thermal stability of PSS, and we used both differential and integral conversional methods to determine the appropriate thermokinetic models for this substance. We also established an autocatalytic model to study the conversion limit time and the maximum rate time of this substance. After calculation, the activation energy of this substance is no more than 60 kJ/mol, and it has other exothermic performances at different heating rates. The results help to optimize the sulfonation process of PSS and analyze the thermal risk of PSS with ammonium sulfate.

The surge in demand for sustainable materials has instigated significant research into versatile substances applicable in fields ranging from everyday commodities to construction and energy. Among these, ionic liquids, notably 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][Tf2N]), have risen to prominence as green solvents. However, an urgent demand exists to comprehend their thermal safety characteristics, particularly for energy applications. Contrary to previous research, which predominantly employed linear fitting or empirical formulas, our study presents a novel non-linear fitting approach to investigate the thermal behavior of [EMIM][Tf2N]. It yields new insights into its activation energy value, marking a significant advance in attaining precise thermal safety data for sustainable construction applications. To ensure safety at elevated temperatures, [EMIM][Tf2N] was selected for comprehensive analysis. Our research evaluated the kinetic model using thermogravimetric analysis coupled with assessing fundamental reaction parameters and simulating thermodynamic equations by identifying hazardous temperatures. This study revealed that the reactivity hazard of [EMIM][Tf2N] escalated considerably when the temperature surpassed 280 °C, emphasizing the importance of process safety. Furthermore, when the temperature exceeded 287 °C, the time to reach the maximum reaction rate (TMR) diminished to less than a day—an aspect crucial to process safety. At temperatures beyond 300 °C, around 70% of the substance was consumed, further underlining the need for stringent safety measures in processing environments. We also considered the impact of different storage containers on thermal safety. The potential runaway temperatures for box-shaped and cylindrical storage containers were established at 270 °C and 280 °C, respectively, providing valuable data for designing safe storage environments. Our research significantly contributes to the prudent utilization and sustainable application of ionic liquids like [EMIM][Tf2N] by considering various safety scenarios and establishing safe temperature ranges.
