Reactions of Co(II) with sodium cyanotrihydroborate in the presence of a series of bidentate and some monodentate phosphines / by Saeed Iftikhar Khan. --
The reactions between Co(C10[subscript4])[subscript2].6H[subscript2]O or CoCl[subscript2].6H[subscript2]O, NaBH[subscript3]CN and some monodentate (PPh[subscript3] and Pcy[subscript3]) and a series of bidentate phosphines ...
Synthesis and biodegradation of model compounds related to hydrocarbon-type dielectric fluids / by Sin-Lan M. Angela Li. --
Uniroyal PA0-20E, an oligomer of 1-octene, is a dielectric fluid proposed as a replacement for polychlorinated biphenyls. No studies on its biodegradation have been reported in the literature to date. This thesis ...
Thermal decomposition and gasification of cellulose and wood wastes / by Peter Fong. --
The thermal decomposition of jack pine bark, white birch sawdust and cellulose has been studied by both isothermal weight-change determinations and dynamic thermogravimetry mostly in inert atmospheres up to 900°C. Gaseous ...
Molecular and intramolecular relaxation processes of small molecules / by Bernard Chi-Cheung Chan. --
The dielectric relaxation method was used to determine the activation parameters of some ethane derivatives and simple amides. A General Radio 1615-A capacitance bridge was utilized to obtain the energy barriers of the ...
Reactions of Ni (II) with sodium cyanotrihydroborate in presence of some bidentate phosphines / by Mohammed Nazrul Islam Khan. --
Cyanotrihydroborate-transiton metal ion chemistry has been reviewed.
Synthetic studies on slaframine / by M. A. Rahman. --
Thjs thesis is concerned with the prelIminary studies in the synthesis of an indolizine alkaloid, slaframine. A Wittig reaction of 3-carbethoxypropyltriphenylphosophonium iodide (43) with 4-pentenal (44) gave ...
Some dielectric and spectroscopic studies on hydrogen bonding / by M.A. Enayetullah. --
Dielectric relaxation studies were carried out principally on some hydroxy compounds (e.g., phenols) and some carboxylic acids in polystyrene (PS) matrices and, in some cases, in compressed solids (CS). The hydroxy compounds ...
Synthetic studies on chaksine / by M.A.J. Miah. --
This thesis is concerned with the studies in the synthesis of a monoterpenoid alkaloid, chaksine. Ethyl 2-n~butyl-4-bromoacetoacetate (11) was treated with sodium azide to give ethyl 2-n-butyl-4-azidoacetoacetate (12), ...
Relaxation processes of polar molecules in some organic glasses / Muhammed Abul Kashem. --
Dielectric absorption studies of a variety of polar solutes containing rotatable groups and of some analogous rigid molecules dispersed in (i) an atactic polystyrene matrix, (ii) glassy o-terphenyl and polyphenyl ether ...
Some relaxation studies of molecular and intramolecular motions in glassy o-terphenyl / by Douglas Louis Gourlay. --
In this work, the results of dielectric studies carried out on a number of molecules of the general form y [symbol] x are presented. These molecules have been studied mainly in two forms: as solutions of glassy o-terphenyl, ...
