Azomacrocyclic derivatives of imidazole: synthesis, structure, and metal ion complexation properties
PublicationNew azocrown ethers comprising imidazoles in the macrocycle have been synthesized. Imidazole, 2-methyl-, 4-methyl-, and 4-phenylimidazole were incorporated to form macrocyclic units by coupling with the appropriate bis-diazonium salts. The syntheseswere performed under high dilution conditions. The X-ray structure of a water adduct of the 21-membered crown ether derivative of 4-methylimidazole 8 has been solved. Metal...

Experimental and predicted physicochemical properties of monopropanolamine-based deep eutectic solvents
PublicationIn this work, the novel deep eutectic solvents (DESs) based on 3-amino-1-propanol (AP) as hydrogen bond donor (HBD) and tetrabutylammonium bromide (TBAB) or tetrabutylammonium chloride (TBAC) or tetraethylammonium chloride (TEAC) as hydrogen bond acceptors (HBAs) were synthesized with different molar ratios of 1: 4, 1: 6 and 1: 8 salt to AP. Fourier Transform Infrared Spectroscopy measurements were performed to provide an evidence...

Electrical properties and structure of lead-borate glass containing iron ions.
PublicationThe ac and dc conductivity in iron–lead-borate glass samples was investigated in the frequency range from 1 mHz to 1 MHz and in the temperature range from 153 K to 423 K. The structure was investigated by the means of atomic force microscopy (AFM) and the crystalline phases (if present) were identified by the means of X-ray diffractometry. Two types of ac electrical behaviour were observed. The first group of glass samples which...

Thermal properties of polyurethanes synthesized using waste polyurethane foam glycolysates
PublicationW pracy przedstawiono wyniki analizy termicznej (DMTA i TG-FTIR) glikolizatów i otrzymanych z nich poliuretanów. Glikolizaty uzyskiwano w reakcji odpadowej pianki poliuretanowej z 1,6 heksametylenodiolem (HDO) przy różnym stosunku masowym pianki do HDO (1:1 - 10:1). Poliuretany syntezowano metodą dwuetapową z prepolimeru (diizocyjanian MDI + glikolizat), który przedłużano handlowym małocząsteczkowym glikolem.

Azomacrocyclic derivatives of imidazole: synthesis, structure, and metal ion complexation properties
PublicationOtrzymano nowe azokorony zawierające resztę imidazolu w makropierścieniu. Na drodze sprzęgania z solami diazoniowymiotrzymano pochodne imidazolu 2-metylo, 4-metylo oraz 4-fenyloimidazolu. Synteza była prowadzona w warunkach wysokiego ciśnienia. Dla 21-członowej pochodnej 4-metyloimidazolu określono strukturę jej adduktu z wodą przy pomocy metod rentgenograficznych.Zdolność kompleksowania jonów metali badano spektrofotometrycznie...

Tunable properties of ionic liquids in supported ionic liquid membranes technology
PublicationImmobilizowane membrany ciekłe są układem, gdzie ciecz osadzona jest w porach porowatego nośnika i jest tam utrzymywana przez siły kapilarne. Takie rozwiązania wykazują wiele zalet, jak zużycie niewielkich ilości fazy membranowej, niska lotność cieczy jonowych,. Efektywność separacji związków z użyciem membran ciekłych zależy głównie od właściwości fazy membranowej. Praca opisuje modyfikacje struktury cieczy jonowych, a zatem ich...

Volumetric properties of zinc(II) chloride in N,N-dimethylacetamide and dimethylsulfoxide
PublicationW oparciu o pomiary gęstości szeregu równomolarnych mieszanin soli Zn(ClO4)2 -ZnCl2 wyznaczono pozorne objętości molowe kompleksów powstających podczas kompleksowania jonów cynku jonami chlorkowymi w dimetylosulfotlenku i N,N-dimetyloacetamidzie w 298.15 K. Uzyskane wyniki jednoznacznie wskazują na to, że w N,N-dimetyloacetamidzie wszystkie kompleksy chlorkowe jonów cynku(II) są czterokoordynacyjne. W dimetlosulfotlenku natomiast...
