Some sodium diethyldithiocarbamate and 8-oxyquinoline based mixtures were tested as potential extractant to concentrate solutions containing ions Cu2+, Co2+, Pb2+, Ni2+, Zn2+, Fe3+, Cd2+ while preparing the samples for ...

New compositions containing some organic inhibitors were tested in the carbon steels and copper alloys etching processes. The analysis of the etching efficiency and harmful products emission proves that significant reduction ...

1-Aryl-4-chloro(2,4-dichloro)-1H-imidazole-5-carbaldehydes reacted with N-bromosuccinimide affording bromides of 1-aryl-2-bromo(2,4-dichloro)-1H-imidazole-5-carboxylic acids which were converted into the corresponding ...

1-Aryl-4-chloro-1H-imidazole-5-carbaldehydes and 1-aryl-4-chloro-1H-imidazole-5-carboxylic acids reacted with sulfur(IV) fluoride to give, respectively, 1-aryl-4-chloro-5-difluoromethyl- and 1-aryl-4-chloro-5-trifluorome ...

4-(Azidomethyl)pyrazole-3-carboxylic acid ethyl esters react with cyanoacetamides in THF solution in the presence of t-BuOK resulting in the formation of 5-oxo-4,5,7,9-tetrahydropyrazolo[3,4-e][1,2,3]-triazolo[1,5-a][1,3 ...

This study is devoted to development of the optimal conditions for synthesis and the study of some “structure – antioxidant activity” regularities of [(1-arylimidazole-5-yl)methylthio]alkane carboxylic acids, which structural ...

В данной статье авторами проанализированы проблемы обучения иностранных студентов в украинском медицинском вузе на примере ВГУЗ «Буковинский государственный медицинский университет», а также сформулированы ...

Робота присвячена синтезу нових похідних 5-(2-нітровініл)імідазолів, дослідженню їх хімічної поведінки в реакції Міхаеля з гетероциклічними СН-кислотами та вивченню протигрибкової і бактерицидної дії. Встановлено, що ...
