This work involves synthesis of different five and six member heterocyclic rings starting from acid hydrazides (m-methyl benzoyl hydrazide and p-nitro benzoyl hydrazide) which were synthesized from their carboxylic acids.
This work is divided into four different parts:
First part:
The aim of the present work is the synthesis of new derivatives of N-substituted diphenyl amine.The Scheme of our work involves Synthesis of different five; six and seven heterocyclic rings starting from diphenyl amine.
First part:
Spectrochemical methodswas employed for determination of wear metals (Fe, Cu, Pb and Al) that result from the internal friction between engine's component after using for a different distances in commercial fuchs lubricating oil. The samples were collected from the engine after running for 0 till 3000Km.
The scheme of this work involves synthesis of different five memberd hetrocyclic rings from ρ-chlorobenzoic hydrazide which was synthesized from it's carboxylic acid.
This work is divided into three parts:
Refluxed ampicillin trihydrate was determined using conventional and derivative UV absorption spectrophotomerty.The calibration curve for refluxed ampicillin trihydrate at 339 nm was found to have a linear range extended from 4 to 200 ppm with relative standard deviation for the slope of 0.0082 and correlation coefficient of 0.9999 with detection limit of 0.5 ppm. The effect of pH on the determination of ampicillin trihydrate at this wavelength was investigated.
A new set of Schiff bases have been prepared in this work, which include:
Diabetes Mellitus is a chronic and complex disease, requiring continued life long management aimed at reducing the high morbidity and premature mortality caused by chronic complications. In both type І and type ІІ diabetes, late diabetic complications in nerve, vascular endothelial, and kidney, increased oxidative stress and it is consequences of either increased production of free radical, or reduced antioxidant defenses, arise from chronic elevation of glucose.
In the present research,synthesis of copolymers containing flourescular naphthalene groups were discussed.The synthesis includes the copolymerization of methacrylic acid or methyl acrylate with 3-(1-naphthl) acrylic acid using benzoyl peroxide initiator as the following brief discription..
Taking in account the basic ideas in coordination chemistry governing the structure and reactivity of these compounds especially those of Palladium and Platinum complexes, a new set of Pd(II) and Pt(II) square planar complexes with varying structural isomerism have been prepared and studied. Their structure and spectral behavior have been discussed based on hard and soft acid base principles, back π-bonding, and redox behavior.
The work in this thesis involves four parts:
Part one: Synthesis of 2,5-disubstituted-1,3,4-thiadiazoles:
For the synthesis of the titled compounds the following sequence of steps (step -1- to step -8- ) were followed.
Step-1- : Synthesis of 2,5-dimercapto-1,3,4-thiadiazole [1].
It was prepared by cyclization of hydrazine hydrate with carbon disulfide in alkaline medium.
