This thesis consists of the synthesis of new liquid crystalline compounds N-{(nalkoxy-4``-bezoyloxy)-4`-benzylidene}-4-butyl aniline which were synthesized according to the following Scheme:
This research is divided into two parts:
Part one:
This part involved in the synthesis of some pyrimidine derivatives which play an important role in the medicinal chemistry because they possess promising cytotoxic activity.The synthesized compounds:
New stationary phase for high performance liquid chromatography has been prepared by the interaction of crystal violet solution with silica gel.The stability of the new attached functional group on the new stationary phase was studied against different solvents such as benzene, ethanol,acetonitrile, acetone, methanol, hexane, chloroform, and petroleum ether as well as NaOH and HCl solutions.
This work involved the use of UV-VIS spectrophotometric and spectrofluorometer to study the photoproperties and the determination of riboflavin in the vitamin synthetic standards either directly from the
The preparation of Bis[2-(6-methoxynaphthalen-2-yl)propanoate] chelate complexes with nickel(II), copper(II), zinc(II), cadmium(II) and tin(II) were described in this thesis.Infrared, ultraviolet–visible, spectrophotometric techniques, magnetic susceptibility, atomic absorption, conductivity measurements and melting point were used to characterize the free ligand and the above chelate complexes. All these
The behavior of some transition metal cations [Cr (III), Fe (III), Fe (II), Co (II), Ni (II) and Cu (II)] were investigated in ammonium alumurea ionic liquid. The study was followed by UV-Visible electronic
spectroscopy to establish their coordination geometry in the liquid and estimate the ionic species attached to the transition metal cations.The reactivity of the metal cations were found to vary from one to
Two kinds of electrodes were prepared in this study based on PVC matrix. Four ion selective electrodes for Chloramphenicol sodium succinate which based on chloramphenicol palmitate.
1. Di-butyl phthalate (DBPH)
2. Di-butyl phosphate (DBP)
3. Di-octyl phthalate (DOP)
4.Tri-butyl phosphate (TBP)
Diabetes is a group of disorders that produce elevated levels of blood glucose. The two main forms of diabetes are type 1and type 2. The cause of diabetes was associated with some endocrine hormones and obesity. This study was focused on diabetes type 2 and its effects on thyroid hormones (TSH, T3, T4),prolactin and cortisol and with body mass index. To achieve this aim 68 diabetic patients type 2 with ages of 35-70 years and 34 healthy people with ages of 35-70 years (control group) were enrolled.
New stationary phase for high performance liquid chromatography has been prepared by the reaction of Neutral red solution with Weakly acidic cation exchanger resin . The stability of the new attached
New stationary phase for high performance liquid chromatography had beenprepared by the reaction of congo red solution with amberlite anion exchange.The F.T.I.R elemental analyses have configured the attachment of congo redon the resin as has indicated by the physical appearance of the new resin.The resin capacities of newly prepared resin has calculated the resin capacityfor the amberlite-congo red resin was found to average 7.36 meq/ gm and for the amberlite resin 3.0 meq./gm.The new stationary phase has been packed into stainless steel column.
