Improved The Properties Of Biolubricant Basestocks
ISBN: 9783845422817 / Angielski / Miękka / 2011 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The industrial use of agricultural commodities has been an issue generating a significant amount of interest. As the cost of petroleum-derived products increases, the need to change to a more biobased economy can be clearly seen. In addition to food uses, plant oils have found their way into industrial products in the plastics, pharmaceutical, inks, adhesives, coatings, and many other industries. The advantages of plant oil-derived industrial products can be illustrated by several of the 12 principles of green chemistry including the call for the use of renewable feedstock, the...

Photostability of Poly(vinyl Chloride)
ISBN: 9783639365108 / Angielski / Miękka / 2011 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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...

General description of heterocyclic derivatives
ISBN: 9783847337416 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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...

Synthesis of Environmentally Friendly Biolubricant Basestocks
ISBN: 9783639338706 / Angielski / Miękka / 2011 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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...

Synthesis of Heterocyclic Derivatives
ISBN: 9783639357868 / Angielski / Miękka / 2011 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 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.
Since, 1,3,4-oxdiazole and 1,2,4-triazole derivatives are the most widely utilized heterocyclic moities, both biologically active and industrially use...
