2-Нитро-1,3-бис(3,3'-дигидроксиметил)-1,2,3-триазолил-2-азапропан (2-НДТАП) представляет интерес в качестве исходного вещества в синтезе высокоэнергетических соединений. В статье рассмотрен синтез 2-НДТАП реакцией азид-алкинового циклоприсоединения 1,3-диазидо-2-нитро-2-азапропана с пропаргиловым спиртом в среде трет-бутилового спирта в присутствии медного катализатора (проволока, порошок меди, оксид меди, нанооксид меди). Исследовано влияние катализатора и температуры процесса на его продолжительность, выход и качество продукта. Структура 2-НДТАП подтверждена методами ИК- и ЯМР-спектроскопии. В результате разработан метод получения 2-НДТАП с выходом 62 % и содержанием основного вещества выше 97 %. 2-Nitro-1,3-bis (3,3'-dihydroxymethyl)-1,2,3-triazolyl-2-azapropane (2-NDTAP) is of interest as a starting material in the synthesis of high-energy compounds. The article discusses the synthesis of 2-NDTAP the reaction of azide-alkyne cycloaddition 1,3-diazido-2-nitro-2-azapropane with propargyl alcohol in tert-butyl alcohol in the presence of a copper catalyst (wire, copper powder, copper oxide, nano copper oxide). The influence of the catalyst and the temperature of the process on its duration, yield and product quality has been investigated. The structure of 2-NDTAP was confirmed by IR and NMR spectroscopy. As a result, a method for obtaining 2-NDTAP with a yield of 62 % and a basic substance content of more than 97 % was developed.

Kinetics Of

The kinetics of oxidation of [Co(en)2SCH2COO]+ with S2O82- was studied in water-methanol and water-tert-butyl alcohol mixtures. Changes in the reaction activation parameters ∆H≠ and ∆S≠ with varying concentration of the co-solvent depend on the kind of the latter, which points to a significant role of salvation effects. The solvation effect on the reaction is discussed based on a comparison of the transfer functions ∆Ht0, ∆St0 and ∆Gt0 for the initial and transition states with the changes in the activation parameters accompanying changes in the CO-solvent concentration. The transfer enthalpies of the reactant were obtained from calorimetric measurements.

Activated Persulfate

In this study, a Fenton-activated persulfate (Fe2+/PS) system was introduced for the efficient degradation of Mordant Blue 9 (MB 9) as a textile dye in an aqueous solution. Results showed that the degradation of MB 9 was markedly influenced by operational parameters, such as initial pH, PS concentration, Fe2+ concentration, and initial dye concentration. Optimal reaction conditions were then determined. Inorganic anions, such as Cl− and HCO3−, enhanced the degradation efficiency of MB 9 under optimal conditions. Addition of HCO3− reduced the degradation performance of MB 9, whereas the addition of Cl− increased the degradation percentage of MB 9. In addition, quenching experiments were conducted using methanol and tert-butyl alcohol as scavengers, and methanol was identified as an effective scavenger. Thus, the degradation of MB 9 was attributed to S O 4 • − and •OH radicals. The degradation and mineralization efficiency of MB 9 was significantly reduced using the conventional Fenton process i.e., Fe2+/ hydrogen peroxide (HP) because of the formation of a Fe complex during degradation. Meanwhile, the Fe2+/persulfate (PS) system improved the degradation and mineralization performance.
