“…At high concentrations of HA in aqueous solution, the activation barrier for HA bimolecular isomerization to ammonia oxide is much lower (approximately 16 kcal=mol), which makes HA highly reactive (Wei et al, submitted). This finding agrees with experimental results showing HA less stable with increasing concentrations in water (especially above 75 mass%) (Iwata and Koseki, 2003).…”

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 watercatalyzed 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.

“…It is difficult to evaluate the biocontrol activity of hydroxylamine because it is unstable, particularly in the presence of iron and high temperature (Iwata and Koseki, 2003) and would be gradually consumed in culture medium. Honda et al (1998) estimated the biocontrol activity of hydroxylamine against F. oxysporum and determined the MIC value as 10 mg/L.…”

IntroductionCyclamen (Cyclamen persicum Miller) is a popular plant for horticulture, and for many years, sales of seeds and saplings have benefited the economy of the Ena-Nakatsugawa district, Gifu Prefecture, Japan. This success can be attributed, in part, to the close attention that gardeners pay to diseases affecting the production of seeds and saplings. Several diseases of cyclamen are caused by fungi and bacteria, such as anthracnose (Colletotrichum gloeosporioides), bacterial bud blight (Pseudomonas marginalis pv. marginalis), fusarium wilt (Fusarium oxysporum Schlechtendahl f. sp. cyclaminis), gray mold (Botrytis cinerea), bacterial soft rot (Erwinia carotovora subsp. carotovora), and bacterial leaf blight (Pantoea agglomerans) (Database of Plant Diseases in Japan, NIAS GenBank, https://www.gene.affrc.go.jp/databases-micro_pl_dis-eases_en.php). In particular, anthracnose and bacterial leaf blight frequently occur in Gifu.Among several bacterial species with fungicidal activity, Bacillus subtilis is well characterized (Weller, 1988). Most fungicidal B. subtilis secrete iturin group compounds, which consist of linear alkyl fatty acids and circular depsipeptides, including D-amino acids, as a highly active fungicidal component (Maget-Dana

“…Iron reacts like plutonium in Reaction (1), but also generates HNO 2 , Reaction (9), giving an overall Reaction (10) when present. Even low concentrations of iron have been found to lower the selfaccelerating decomposition temperature (SADT), for instance SADT for 50 wt.% HA in water goes from 80°C with 0.1-1.0 ppm Fe 3+ to 55°C with 5.2 ppm Fe 3+ [17] . For higher concentrations of HA in water (85 wt.%), the required concentration of Fe 3+ for autocatalytic onset is even lower [18] .…”
