Epoxidation of trimethylolpropane esters based Jatropha curcas oil using performic acid

by Nadia Salih,
Abstract : Epoxidized Trimethylolpropane esters (ETJO) based Jatropha curcas oil were produced by epoxidation process of TMP esters (ETJ) with performic acid (HCOOOH) formed in situ by the reaction of hydrogen peroxide (H2O2) and formic acid (HCOOH). The effect of several reaction parameters such as hydrogen peroxide to TMP esters molar ratio, formic acid to TMP esters molar ratio, temperature, and time reaction on the epoxidation process as well as on the oxirane oxygen content (OOC) and iodine value of the epoxidized TMP esters were examined. The epoxide group of ETJO was analyzed by using Fourier Transformation Infrared Spectrometer (FTIR) and Nuclear Magnetic Resonance spectroscopy (1H NMR and 13C NMR). FTIR spectrum analysis for ETJO showed the appearance of the peak at 825 cm-1 and 908 cm-1 for epoxide groups. The 1H NMR analysis for ETJO confirmed the presence of epoxide group at 2.88 ppm and 13C NMR analysis showed carbon signals of epoxide group at 54-57 ppm. ETJO obtained at the optimum conditions had iodine value of 1.4 mg/g, the oxirane oxygen content at 4.38 % and relative conversion oxyrane (RCO) of 87%. The reaction yield was 91 %.

Review on kinetics of substitution reactions with amino acids at chromium (III) centre

by Mushini Venkata Subbarao,
Abstract : The research work on the kinetics of substitution reactions between amino acids and chromium(III) complexes are not dynamically studied by researchers. These substitution reactions are feasible to study in aqueous medium under in acid and alkaline conditions. So an opportunity is there in the research for the study of kinetic reactions with different chromium(III) complexes by using amino acids as ligands. Also good prospect is there in the preparation of complexes with chromium(III) and amino acids and studies of their kinetics, spectral properties as well as speciation. In this review paper, important points are related to Chromium(III) and amino acids are presented and relevant research papers are reviewed related to the kinetics of substitution of different chromium(III) complexes with amino acids.

Quality analysis of Local and Imported Vegetable Oil Brands Consumed in Hossaena Town, Ethiopia.

by Tadege Belay, Dereje Bizuayehu,
Abstract : The present research work was conducted to determine the extent of cholesterol, acid value, and peroxide value from six vegetable oils (Tena soybean, Tena sun flower, Sunny soybean, sunny sunflower, Nigger and palm oil) commercially available at Hossana markets. Cholesterol content were estimated spectrochemically using ultra violet visible spectrophotometer; whereas acid and peroxide values titrimetrically using potassium hydroxide (KOH) and sodium thiosulfate respectively. Results of analysis revealed that the cholesterol contents varied from 25.6 ± 0.75 to 217.4 ± 0.32 mg/L corresponding with Nigger to Tena soybean oil. The acid and peroxide value contents among vegetable oil samples ranged from 0.523 ± 0.052 to 3.93 ± 0.076 mg KOH/g sample and 0.92 ± 0.015 to 3.2 ± 0.012 meq.Oxygen/Kg with respect to Tena sunflower and palm oil samples. Nigger and Palm oils have higher level of free fatty acids and rancidity which translates into decreased oil quality. The current research has been able to show that there is no cholesterol free oil in the market as opposed to what is argued on the vegetable oil brand labels. Therefore, companies producing and marketing vegetable oils are enjoined to desist from misleading the public by labeling their products as “cholesterol free”. They should indicate the amount of cholesterol, acid value and peroxide value present in the vegetable oil, no matter how small the quantity might be; as well as other ingredients through critical analysis.

by GIta Rani, Monika,
Abstract : Polypyrrole and tungstate doped polypyrrole composites of different weight percentage have been prepared by chemical oxidation polymerization technique by using ammonium persulphate as oxidizing agent. All the samples of polypyrrole and polypyrrole composites of tungstate of different concentration were characterized by FTIR, XRD, SEM and DSC techniques. The FTIR spectra of polyprrole and its composites of tungstate revealed the polymerization of pyrrole and successful doping of tungstate in polypyrrole. XRD analysis showed amorphous nature of polypyrrole and crystallinity of polypyrrole composites. The SEM monographs showed globular shape particles of polypyrrole and uniform distribution of tungstate in polypyrrole matrix. The DSC analysis reveals that the thermal stability of polypyrrole was enhanced by doping of tungstate in polypyrrole matrix.

Biosorption of lead by biomass of dried Sargassum crassifolium

by Lily Surayya Eka Putri, Eka Syafiqa, Eka Apriliyani,
Abstract : One of the heavy metal pollutants emerged highly concentration in the watershed of Jakarta city, Indonesia is lead (Pb). Removal of lead using a biological method by using macroalgae is an efficient method from wastewater. Sargassum crassifolium is the original species of macroalgae from Indonesia that was used in this study to analyze the ability of adsorption of lead from aqueous solution and industrial wastewater. Samples collected at Pari and Pramuka Island, Seribu Island, North Jakarta, Indonesia were studied to adsorb lead with a variety of adsorption time of 10, 20, 30, 45, 60, 90 and 120 minutes and a variety of initial concentration of lead, 200, 300, 400,500, 750 and 1000 mg/L, using duplicate assessment at the pH 5. The removal of lead from the industrial wastewater using macroalgae S. crassifolium should further be analyzed. The highest lead removal was 98.4 in the concentration of 1000 mg/L achieved within 60 minutes. The binding of lead by S. crassifolium followed the Freundlich model (R2 = 0.976) with the maximum adsorption capacity was 55.56 mg/g. The removal of lead from wastewater was 75% for 60 minutes contact time with the final concentration was 0.01 mg/L under the safe limit for the environment. Thus, S. crassifolium has a high prospect as an adsorbent of heavy metals in industrial wastewater treatment.
