Abstract

Since the 1990 s, sporadic explosion accidents have occurred in the chemical industry. Accidents related to nitrification reactions or nitrification substances have had the most severe consequences. One reason for this phenomenon is the high risk of nitrification by-products, which are liable to combust and explode. Special attention must be paid to the production, collection, storage, and disposal of nitrification by-products. This study examined the thermal stabilities of the phenolic by-products created during nitrobenzene formation. The thermal stabilities of three representative aromatic nitrophenol by-products were determined using differential scanning calorimetry, accelerating rate calorimetry, and thermogravimetric analysis. Advanced thermodynamic models were established for calculation and fitting, which provided reliable data support for exploring the intrinsic stability of nitrification by-products.
