Experimental and theoretical study of molecular H-complexes of ketones with diphenyl-p-chlorophenyl carbinol
(Elsevier, Amsterdam, 1992)
The interaction between hydroxy-diphenyl-[4-chlorophenyl]-methane and some typical ketones was studied both in theoretical and experimental ways. It was concluded that the Cl-substituted phenyl group contributes to the ...
Synthesis of some new N-monosubstituted fluoroacetamides
(Journal of Fluorine Chemistry, 1992)
Twenty new N-monosubstituted fluoroacetamides with potential toxicological properties have been synthesized by acylation of the corresponding amines with fluoroacetyl chloride. The substituents were cycloalkyl or various ...
Conformations in unsymmetrically N-n-propyl-N-substituted 2-phenylacetamides
(Elsevier, Amsterdam, 1992)
As a part of a study on the structural characteristics of some new various N-alkyl-N-substituted 2-phenylacetamides the infrared and 1H N.M.R. spectra were obtained and interpreted. The synthesis of a various N-n-propyl-N-alkyl ...
On the formation of CoAPSO-44
(Butterworth-Heinemann, 1992)
Hydrothermal synthesis of CoAPSO-44 in the presence of cyclohexylamine (CHA) as the template is generally accompanied by the formation of an unknown phase, “Co(APSO)N.” Electronic spectroscopy indicates that CO(APSO)N ...
Retention behavior of some amides in reversed- and normal-phase thin-layer chromatography
(Springer Heidelberg, Heidelberg, 1992)
The retention behavior and separation ability of reversed- and normal-phase TLC with, polar and nonpolar mobile phases, has been studied by measuring the retentions of a series of amides. The retention behavior and separation ...
Reološka i druga svojstva N-metilmorfolin-N-oksidnog rastvora celuloze za vlakna / Rheological and other properties of cellulose solution in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
Između različitih rastvarača za direktno rastvaranje celuloze i primene ovih rastvora za proizvodnju hemijskih celuloznih vIakana najperspektivniji je N-metilmorfolin-N-oksid (NMMO). Teižište ovog rada je na istraživanju ...
Cathodic processes on corroding low-carbon steel: the effect of the degree of deformation
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The influence of the degree of deformation of low-carbon steel (0.48% Mn, 0.47% Si, 0.085% C) caused by mono-axial stretching was investigated with respect to the kinetics of electrochemical hydrogen evolution and the ...
Kristalisanje koncentrovanih rastvora celuloze u N-metilmorfolin-N-oksidu / Crystallization of concentrated cellulose solutions in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
U istraživanju mogućnosti dobijanja hemijskih celuloznih vlakana bez upotrebe ugljen disulfida posebna pažnja je posvećena takvim direktnim rastvaračima celuloze kao što su tercijerni amini. U ovom radu proučavane su pojave ...
Hydrogen peroxide oxidation on passive iron in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The kinetics of hydrogen peroxide oxidation were studied on passive iron in alkaline solutions of pH ranging from 9.8 to 13.8, using the rotating disk electrode. Measurements were taken using the linear sweep technique. ...
Flow regimes and liquid mixing in a draft tube gas-liquid-solid fluidized bed
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with ...
