| Description
| - Pomocí batch experimentů byla studována alkalická hydrolýza 2,4,6-trinitrotoluenu v konických baňkách překrytých hliníkovou fólií. U pokusů se startovním pH 12 došlo k 95% degradaci TNT, kdežto se startovním pH 11 byla dosažena pouze 20-25% redukce. Ve všech experimentech byl produkován stabilní hlavní intermediát, který nebylo možno identifikovat. Data z experimentů byla využita na stanovení celkové stechiomerie TNT a hydroxylových iontů. Přibližně 100 molů hydroxylových iontů je potřeba na 1 mol TNT. Avšak kontrolní experimenty prokázaly, že 13 molů bylo spotřebováno na reakce nesouvisející s TNT. Rychlostní kontanty a aktivační energie byly určeny pomocí isotermálních dat a kinetický model byl potom použit na předpovězení dat v neizotermálních pokusech. (cs)
- Alkali hydrolysis of 2,4,6-trinitrotoluene (TNT) was studied using batch experiments with starting pH values 11 and 12 in glass conical flasks covered with aluminum foil. Isothermal (25 and 40 °C) as well as non-isothermal experiments were conducted. Experiments starting at pH 12 resulted in >95% reduction in the concentration of TNT; those starting at pH 11 had a maximum reduction of 20-25% in TNT concentration. In all the experiments, one major stable intermediate was produced but it could not be identified. The experimental data were used to determine the overall stoichiometry of TNT and hydroxyl ions. Approximately 100 mol (standard deviation 11.4) of hydroxyl ions were consistently consumed per mole of TNT. However, control experiments showed that all but 13 mol (standard deviation 2) of hydroxyl ions were consumed in reactions not related to TNT. A simple kinetic model involving formation of the intermediate was proposed to account for changes in concentrations of TNT and hydroxyl ions. The r
