Abstract: The new metal (II) complex [Fe (asp)2 Cl2] has been synthesized by both the solution and solid state methods and were characterized by elemental analysis, molar conductance, magnetic moment and spectral studies as well as biological evaluation. On the basis of spectral studies, magnetic moment and molar conductance, octahedral geometry was assigned to the complexes and suggest the free ligand as bidentate. The authors recommended the use of solvent-free synthesis over solution based due to its time management, inexpensive and non-hazardous.

Key words: Solvent-free, solution-based, biological, complex

Abstract: The current work is the concentrate of assembling and consumption portrayal of Aluminum 6013/Red mud particulate MMCs in basic medium. The MMCs are produced by utilizing vortex strategy where fluid soften metallurgical procedure was utilized which is additionally called stircasting technique. Composite materials containing red mud particulates with 2, 4 and 6 weight rate were produced by the above strategy. Aluminum 6013 alloy was likewise casted so as to contrast the outcomes and composite materials. The samples are machined according to ASTM principles. The tests utilized for portrayal concerning corrosion properties were static weight reduction corrosion test and potentiodynamic polarization. tests were done in sodium hydroxide arrangements with.....

Abstract: Background: Salt in crude oil during refining processes causes problems such as corrosion, fouling of catalysts, etc. Refineries use diverse demulsification methods that are relatively expensive. Sometimes the desalting methods employed by some crude oil refiners have uncertain efficiencies. Because of that, this paper presents economically advantageous and efficient method to demulsify crude oils. Materials and Methods: In this research, the Ghanaian locally manufactured alcoholic beverage (Akpeteshie) was used as a demuslsifier to desalt crude oils. To prepare spilled crude oil, some of the crude was poured into some seawater. The mixture was left to sit for two days before the crude was cleaned from the seawater. For desalting, the crude was heated to 110 oC......

Abstract: In Nigeria, Sugarcane Bagasse (one of the by-products of sugarcane processing) is typically seen as an agricultural waste with few commercial utilization and the accumulation of this sugarcane bagasse is considered as an environmental concern as it causes environmental pollution in areas where it is disposed. The conversion of this waste to wealth was studied by way of revealing its remarkable potential for use as a grant of cellulose (an unconventional source) for the manufacturing of cellulose derivatives (derivatized herbal polymers) such as CarboxyMethyl Cellulose (CMC) which is quite referred to for its good sized industrial applications.39.2% of cellulose was taken out from sugarcane bagasse via alkali remedy and nitric acid hydrolyzed process. The......

Abstract: The thiazole ring can be constructed from acyclic precursors by a variety of approaches among which the classical Hantzsch [3 + 2] ring formation method remains the formost. Next to it stands in wide applicability, the [4 +1] ring construction route. For a practical synthesis of the thiazoles presently targeted, an appropriate route, among these suggested by previous work, need to be selected. The use of an unsymmetrical 2-bromo-1,3-diketone derivative shown above would, result in the formation of isomeric thiazoles with 5-hetaroyl or 5-benzoyl substituents. In addition, such ketones, are not readily prepared. However, this can be done by the Claisen condensation of Me-CO-Het, where Het represents a heterocyclic group, with ethyl benzoate......

Abstract: Background: Sulphur in petroleum coke makes it cheaper or less desirable because of regulations set by nations and environmental problems caused by the sulphur. Manufactures of Petroleum coke mostly remove the Sulphur from the product after manufacturing using high heat that makes the cost of producing the product having less sulphur more expensive. To reduce the cost of sulphur removal from the petroleum coke, this research employed oxidative extractive desuphurisation method. Materials and Methods: In this research, desulphurization of both spilled and unspilled crude oil were conducted to verify the effectiveness of the method employed. Some crude oil was poured into seawater, cleaned, and then tested for sulphur content using Sulphur in Crude......

Abstract: In the framework of the transformation of natural phosphate from Tapoa (Niger) for use in agriculture, a study of grindingfollowed by chemicalanalysiswasundertaken. Tworepresentativesamples E1 and E2 werecollected. The differentmethodsused show on the one hand, that the content of phosphoruspentoxide (% P2O5) increaseswhen the diameter of the sievedecreases. On the other hand, the highest content of phosphoruspentoxideisobtained in the fraction between 200-125 μm. These contents are 20.72% for sample E1 and 21.10% for sample E2. Theseresultsalsoindicatethat the mass percentage is more important in the fraction below 125 μm (<125 μm). Fluorescence chemicalanalysis shows a P2O5 content of 18.20% and 15.70% respectively in samples E1 and E2.
