The scheme of this work involves synthesis of different five and six membered heterocyclic rings starting from 4-nitrophenyl hydrazine and two different acid hydrazides (benzoic hydrazide and p-chlorobenzoic hydrazide) which were synthesized from their carboxylic acids.This work is divided into four different parts:
Cephalexin is a medical drug administrated commonly for the treatment of infections.Two methods were examined for determination of cephalexin based on conventional and derivative UV absorption spectrophotometry.The calibration curve at 262 nm has linear range extended from (1.5-100) ppm with relative standard deviations for the slope of 0.91 and correlation coefficient of 0.9993. The effect of pH on the determination of cephalexin at this wavelength was also investigated.
This study represents a small contribution to draw attention towards the water quality with respect to the amount of the metal ions (calcium, magnesium, chloride, copper, iron and lead) in some Iraqi water resources (tap, river and ground water).
This study includes preparation number of azo purines and pyrimidines derivatives were prepared by coupling of nitrogen bases with pheny1 diazonium salt.Toverify the prepared compound ultraviolet and visible spectrum(UV-Vis),fourier transforms infrared spectrum(F.T.IR)and the ratiosof (C.H.N.) were calculated by specific analysis of the elements.
In an attempt to introduce the azomethine group in the structure of naphthaldehyde ring , which is known to posses a number of therapeutical applications , and in a purpose of investigating the coordination behavior of the new compounds towards transition metal ions .
Triethanolamine – glycerol maleate polymer was prepared,and identified by F.T.I.R. spectroscopy then swelling tests were performed for this polymer in different solvents.The adsorption processes of the some dyes compounds: MO,MB, MV and SO in aqueous solutions on the surface of this polymer were investigated by the use of UV–visible spectrophotometry and also studied at different: temperatures, ionic
This work represented a contribution to draw attention towards the amount of metals in Basra and Kirkuk crude oil blends. These metals may effect the processing refineries of crud oils. In chapter one of this thesis, an introduction was given on the crude oil and it's origin including both inorganic and organic theories; also the composition and types of crude oil, the importance and the problems associated with the presence of the metals. Finally, the methods used for the determination of metals were given.
The current study involves the preparation of number of urea derivatives from reaction of urea or thiourea with aromatic amines as in compounds:"Phenylthiourea, N-phenylurea, N-(2-methoxyphenyl) urea, N-(4-aminophenyl) urea, N-(2-methylphenyl) urea, N-(2-methoxyphenyl) thiourea, N-[4- (amino carbonyl) amino phenyl] urea, N-[4-(amino carbonyl) amino phenyl] acetamide, N-pyrazin-2-ylurea, N-pyridin-2-ylurea, N,N´-bis(3-bromophenyl)urea, N,N´-bis(2-methoxyphenyl)urea ".In addition to the preparation of three compounds
The work in this thesis include the preparation and characterization of a series of Vanadium (IV) in the term of (VO+2) ion, Chromium(III) and Zinc complexes with five (O,O),(N,N), (O,N) donor ligands, these ligands include:mandilic acid (L1),0-phenylen di amine (L2),benzilic acid (L3),pyruvic acid (L4) and N-N' bis(salicylidene)ethylene di amine(L5), later was prepared ( L5) from the reaction of ethylene diamine with salicylaldehyde.The characterization of all the complexes resulti
