Co-oxidation in supercritical water : methylphosphonic acid-ethanol and ammonia-ethanol model systems
Supercritical water (SCW) is an effective solvent for the destruction of organic compounds by oxidation. Because both organics and oxygen have high solubility in water above its critical point (To = 374 °C (647 K), Pc = 221 bar), they can be reacted together in a single phase which avoids mass …

Oxidation kinetics of methylphosphonic acid in supercritical water : experimental measurements and model development
… phosphorus-containing product was phosphoric acid, while the carbon-containing intermediates, carbon monoxide and methane, were present in varying concentrations in addition to final carbon-containing product, carbon dioxide. Methane was only a minor product, with a carbon yield less than 20% …

Development of a ReaxFF force field for glyphosate and investigation of its abiotic degradation pathways
… DFT energies calculated for glycine (GLY), aminomethylphosphonic acid (AMPA), and methylphosphonic acid (MPA). Umbrella sampling calculations were carried out using two conformations of monoanionic (GLP-) and two conformations of dianionic (GLP2-) glyphosate. The GLP2- simulations yielded free …

The Growth and Characterization of Alkylphosphonic Acid Self-Assembled Nanofibers
… solutions of short chain-length alkylphosphonic acids (APAs) in ethanol. A special emphasis was placed on the creation of APA SANs isolated from the immersed Al source and development of analysis techniques for artifact reduced characterization of as-grown individual SANs. Novel immersion growth …

Understanding the effects of promoters on the direct synthesis of hydrogen peroxide over supported palladium catalysts
… The addition of promoters (e.g., inorganic acids, halide salts) is a common method to improve H2O2 selectivity and several studies have investigated the effect of the addition of a cocktail of promoters on H2O2 rates and selectivities. However, very few studies have illustrated the …

Interfacial Energy Transfer in Small Hydrocarbon Collisions with Organic Surfaces and the Decomposition of Chemical Warfare Agent Simulants within Metal-Organic Frameworks
… substituent to form strongly bound methyl methylphosphonic acid (MMPA). With similar IR features of MOF-808 upon DMCP exposure, the reaction pathway of DMCP in Zr6-MOFs may be similar to that for DMMP, but with the final product being methyl chlorophosphonic acid (elimination of the …
