A Reaction of Thioamides with Zinc Ammoniates Leading to Simple Amidines. Discovery of a New Zwitterionic Monomethylamidine
PublikacjaThe reaction of thioamides with the R1R2N-ZnCl ammoniates leads to N-mono-, N,N'-di-, N,N-disubstituted, and unsubstituted amidines with high concns. of amines in abs. ethanol. The efficient direct formation of the N,N'-dimethylamidine can be explained by a greater reactivity of methylamine compared with dimethylamine. Discovery of a new zwitterion (induced by a carbonyl oxygen) suggests that the stabilization in the thymine...

Esterification kinetics of glycerol with fatty acids in the presence of zinc carboxylates: Preparation of modified acylglycerol emulsifiers.
PublikacjaZbadano zależności kinetyczne estryfikacji glicerolu kwasami tłuszczowymi (C12:0 - C18:0), prowadzonych w obecności soli cynku tych kwasów tłuszczowych. Przeanalizowano wpływ temperatury, stężenia karboksylanu oraz budowy części hydrofobowej kwasu tłuszczowego i karboksylanu, na postęp reakcji estryfikacji. Wyznaczono wartości odpowiednich stałych szybkości reakcji, energii aktywacji oraz maksymalnej zawartości monoestru glicerolu,...

Deep eutectic solvents based assay for extraction and determination of zinc in fish and eel samples using FAAS
PublikacjaA new assay based on effective (high recovery) extraction by means of deep eutectic solvents (DESs) was developed for ppb level determination of zinc in fishes and eel samples. Choline chloride and Phenol in a 1:2 M ratio was selected as optimal DES-based extraction solvent. 8-Hydroxy quinoline was used as a chelating agent for zinc ions. The optimized conditions were found at pH value of 8, ligand concentration of 10 mg/L, THF...

Effect of Thermal Shock During Legionella Bacteria Removal on the Corrosion Properties of Zinc-Coated Steel Pipes
PublikacjaThe purpose of this investigation was to conduct the failure analysis of a water-supply system made from zinc-coated steel. The observed corrosion process had an intense and complex character. The brownish deposits and perforations were present after 2-3 years of exploitation. The electrochemical study based on the Tafel polarization, corrosion potential monitoring, and electrochemical impedance spectroscopy together with microscopic...

Solvation numbers of manganese(II) and zinc(II) perchlorates in methanol obtained from volumetric and compressibility properties
PublikacjaZmierzono gęstości roztworów nadchloranów manganu(II) i cynku(II) w metanolu w temperaturach: 283.15, 288.15, 293.15, 298.15, 303.15, 308.15, 313.15 K. Ponadto wyznaczono szybkości rozchodzenia się dźwięku w badanych roztworach w 298.15 K. Uzyskane wielkości pozwoliły na obliczenie pozornych objętości molowych oraz pozornych molowych ściśliwości adiabatycznych elektrolitów w metanolu. Oszacowane wielkości graniczne wykorzystane...
