Intramolecular dehydration of L-glutamic acid / Intramolekulska dehidratacija L-glutaminske kiseline
(Srpsko hemijsko društvo, 1989)
A number of various thermal dehydrations of L-glutamic acid were performed in order to obtain crude L-pyroglutamic acid. Some old procedures and some new ones were investigated. Also, a great deal of work was done on the ...
Preparation and properties of (2-nitrophtalocyanato)copper(II)
(Serbian Chemical Society, 1989)
The synthesis of (2-nitrophthalocyanato)copper(II) is described, and its X-ray powder diffraction pattern, solubility, electronic and infrared spectra, and thermal stability are reported. The product contains as an impurity ...
Diamine Incorporation in An Amorphous Nickel(II) Aluminosilicate
(Taylor & Francis, 1989)
Treatment of an amorphous nickel(II)-substituted aluminosilicate (NiAS) with 1,2-diaminoethane (en),
1,2-diaminopropane (pnd) and 1,3-diaminopropane (tmd) gives materials (NiAS-en, NiAS-pnd and NiAS-tmd) that are characterized ...
Synthesis and Characterization of Some Nitro-Substituted Phthalocyanines of Nickel(II), Cobalt(II) and Copper(II)
(Taylor & Francis, 1989)
Synthesis of the peripherally substituted (phthalocyaninato)metal derivatives (NO2)4PcM (M α Ni, Co, Cu; NO2 groups are in 1,8,15,22- or 2,9,16,23-positions) is described, and their X-ray powder diffraction patterns, ...
Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier Science Sa, Lausanne, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
