UNDERSTANDING REACTIVE HAZARDS USING MOLECULAR SIMULATION: MECHANISMS OF HYDROXYLAMINE DECOMPOSITION

Reactive hazards have been a significant concern for the chemical process industries. Without sufficient control of chemical hazards and risks, reactive incidents have caused catastrophic consequences for humans and the environment worldwide. In order to help understand and evaluate reactive hazards, calorimetric investigations have been employed to characterize reactive chemical behavior. However, with the development of computer resources and computational chemistry, molecular simulation has become a powerful and reliable tool to complement and guide experimental testing. In this article, hydroxylamine (HA) calculations demonstrate the application of molecular simulation for understanding and controlling reactive hazards. Using the quantum mechanical software Gaussian 03, HA bimolecular or water-catalyzed HA isomerization to ammonia oxide in aqueous solution was identified as the most likely decomposition pathways. Based on these molecular simulation results, recommendations are provided for safer handling of HA.

Dustiness and Deagglomeration Testing: Interlaboratory Comparison of Systems for Nanoparticle Powders

Different types of aerosolization and deagglomeration testing systems exist for studying the properties of nanomaterial powders and their aerosols. However, results are dependent on the specific methods used. In order to have well-characterized aerosols, we require a better understanding of how system parameters and testing conditions influence the properties of the aerosols generated. In the present study, four experimental setups delivering different aerosolization energies were used to test the resultant aerosols of two distinct nanomaterials (hydrophobic and hydrophilic TiO₂). The reproducibility of results within each system was good. However, the number concentrations and size distributions of the aerosols created varied across the four systems; for number concentrations, e.g., from 10³ to 10⁶ #/cm³. Moreover, distinct differences were also observed between the two materials with different surface coatings. The article discusses how system characteristics and other pertinent conditions modify the test results. We propose using air velocity as a suitable proxy for estimating energy input levels in aerosolization systems. The information derived from this work will be especially useful for establishing standard operating procedures for testing nanopowders, as well as for estimating their release rates under different energy input conditions, which is relevant for occupational exposure.
