The work described in this thesis, potasium-2-amino acetate benzothiazole chelate complexes were prepared. Infrared, ultraviolet-visible, spectrophotometric techniques, magnetic susceptibility, atomic absorption conductivity measurement and other physical properties were used to characterize the free ligand and the above chelate complexes. All these compounds were act as stabilizer in PVC films. The rate of photodegradation and photostabilization of PVC film were monitored by measuring the carbonyl, polyene and hydroxyl indices (Ico, Ipo and IoH) values as afunction with irradiation time...

Since, 1,3,4-oxdiazole and 1,2,4-triazole derivatives are the most widely utilized heterocyclic moities, both biologically active and industrially useful, thus, the aim of this work is: Firstly, to synthesis a new series of 2,5-disubstituted-1,3,4-oxadiazoles and substituted 1,2,4-triazoles. Secondly, to investigate the liquid crystalline properties and biological activity of the synthesized series.

Poly(vinyl chloride) is second only to polyethylene among five kinds of general plastic materials, which was widely used in the industries including architecture, electronic, chemical engineering, packaging, transportation, etc.However, low photostability of PVC leads to hydrogen chloride loss,discoloration, and finally serious corrosion phenomena,accompanied by changes of physical and chemical properties of PVC. The low cost and the good performance of poly(vinyl chloride) products have increased the utilizationof this polymer in building, mainly in exterior application, such as window...

Heterocycles play an important role in biochemical processes because the side groups of the most typical and essential constituents of living cells are based on aromatic heterocycles. The presence of heterocycles in biology, pharmacology, optics, electronics, etc. is very well known. Between them, sulfur and nitrogen-containing heterocyclic compounds have maintained the interest of researchers through the development of organic synthesis. Furthermore, azole antifungal agents are the largest class of antimycotics available today. Fused and pendent heterocyclic rings are a ubiquitous feature of...

Plant oils and fats are important constituents of human and animal foodstuffs. Certain grades are industrially used and, together with carbohydrates and proteins, are important renewable resources compared to fossil and mineral raw materials, whose occurrence is finite. In concepts for new products, the price, performance, and product safety criteria are equally important and have a correspondingly high importance right at the start of product development. To ensure a high degree of product safety for consumers and the environment, renewable resources have often been shown to have advantages...
