Chemical synthesis

Specifically, nitration plays an important role in regulation of key enzyme activities and signal transduction networks. Tyrosine is one of the 21 amino acids and is important in the synthesis of certain hormones. Nitration of tyrosine can affect protein function, which can in turn link nitroxidative stress to alterations of molecules present in disease (Peluffo et al. 2007). Potential activation of proteins, specifically tyrosine, can…

polymerization reaction is called as polythene. Globally about 80 million tons of polyethylene is produced. The important application of the polymer is for packing. The monomer used in this reaction is C2H4. The monomer is usually produced from petro chemical process or by dehydration of ethanol. The most widely used catalyst for the polymerization of ethylene are titanium(III)chloride which is popularly called as the Ziegler Natta catalyst and also Philips catalyst is widely used. The…

Microwave (MW) assisted Esterification of Benzoic Acid (BA) offers the advantage of transformation of energy and heating throughout the volume efficiently in a shorter period and eliminates the use of excess solvent, during the course of reaction. The present study aims to assess the conversion and selectivity for the production of methyl benzoate compounds by esterification of benzoic acid using microwave irradiation. Effects of operating parameters such as reaction time, feed composition,…

Lipases from thermophiles are expected to play a significant role in industrial processes, since they are thermostable and resistant to chemical denaturation. Thermostable lipases are employed in various industries which includes food and diary, fat and oil modification, detergent, cosmetic, pharmaceuticals, organic synthesis, oleo-chemical and biodiesel production. The high potential of lipase application in various industries has resulted in increasing demands for new lipase which is…

unknown ended up being calcium chloride, however, until the pH test, ammonium chloride was still a possibility because the ammonium chloride could have been ground up. Table 1 shows this, as well as the disparity of the pH values of the compounds. Chemical Physical Characteristics…

can be stated as a chemical compound of Silicon and the carbon. Edward G. Acheson was running an experiment on the synthesis of diamonds. At that time, it was produced by a high temperature electro chemical reaction of sand and carbon. We can also find the silicon carbide very rarely in nature in very small amounts. Also Edward G. Acheson was the first person to synthesize Silicon carbide. He used to pass an electric current through a mixture of carbon and clay for the synthesis of SiC. Still…

The pyrylium synthesis was ____ based on the NMR, and the salt color that was in agreement with others in the section. The wavelength of maximum absorbance for pyrylium salt 1 was __, based on the average maximum absorbance for all those who synthesized the molecule, which…

3.2 Mechanochemical synthesis The mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP 27…

enormously and has been used to produce many materials including metals, oxides, organic sand pharmaceutical products. Many other well known industrial processes produce materials which have dimensions in the nanometre size range. One example is the synthesis of carbon black by flame pyrolysis which produces a powdered form of carbon with a very high surface to mass ratio. This is usually highly agglomerated but has a primary particle size which can be of the order of 100 nm. Worldwide…

these properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective…
