AB  - In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an adsorbent. The external mass transfer coefficient (k(f)), the surface diffusion coefficient (D-s) and the standard free Gibbs energy were calculated for p-nitrophenol in the presence of different secondary amide concentrations. The analysis established that there are correlations between structural parameters of amides, on the one hand, and diffusion and thermodynamic parameters for p-nitrophenol adsorption process, on the other. It was noticed that voluminous hydrophobic amides decreased the adsorption capacity of p-nitrophenol on activated carbon. On the basis of the results obtained for external mass transfer coefficients, it is assumed that amides cause the reduction of adsorption capacity of p-nitrophenol onto activated carbon by concentrating at the solid/liquid interface.

AB  - This paper reports the results of FTIR study of N-tert-butylacetamide in carbon tetrachloride solution and in presence of seven different molecules as H acceptors. The spectroscopic characteristics for N-H center dot center dot center dot O hydrogen bonded complexes are given. Also, the equilibrium constants for 1:1 complex formation, at 25 degrees C were determined by using IR measurements. Frequency shifts of carbonyl stretching vibration nu(C=O) of N-tert-butylacetamide in the same organic H acceptors was also investigated. The wavenumbers of carbonyl stretching vibration nu(C=O) were correlated with the solvent acceptor number (AN) and the linear solvation energy relationships (LSERs).

AB  - This paper reports the results of the study of hydrogen bonding complexes between secondary amides and various aromatic hydrocarbons. The possibility of using chemometric methods was investigated in order to characterize N-H...π hydrogen bonded complexes. Hierarchical clustering and Principal Component Analysis (PCA) have been applied on infrared spectroscopic and Taft parameters of 43 N-substituted amide complexes with different aromatic hydrocarbons. The results obtained in this study are in good agreement with conclusions of other spectroscopic and thermodynamic analysis.

Metodama klaster analize i analizom glavne komponente utvrđene su razlike među N-H...π kompleksima na osnovu baznosti proton akceptora.

AB  - This paper reports the results of an FT-IR and NIR study of N-methylformamide in carbon tetrachloride solution in presence of ethers as the O-electron donors, i.e., diethyl ether (DEE), diisopropyl ether (DiPE), methyl t- -butyl ether (MtBE), dibutyl ether (DBE), dipentyl ether (DPE), tetrahydrofuran (THF) and tetrahydropyran (THP). The spectroscopic characteristics of the N-H···O hydrogen bonded complexes are given. In addition, the equilibrium constants for 1:1 complex formation were determined at 25°C using Mid-IR and NIR measurements.
