Extraction of Thevetia peruviana Seed Oil and Optimization of Biodiesel Production Using Alkali-catalyzed Methanolysis
Abstract: Normal 0 false false false EN-US X-NONE X-NONE Crude Thevetia peruviana seed oil was used as a feedstock for biodiesel production using alkali-catalyzed methanolysis. Effect of various solvents and solvent combinations on the extraction of seed oil showed that chloroform is the best amongst all other solvent studied with 48% w/w oil yield. The optimized process conditions for Thevetia peruviana biodiesel production were an oil-to-methanol ratio of 1:6 w/w, catalyst …

Evaluation of the Emission and Engine Operability of Biodiesel and Biodiesel Blends Produced from Alkali-Catalyzed Esterification and Transesterification of Jatropha Oil Feedstock
Abstract: This study reports on the engine performance analysis of biodiesel and blends produced from jatropha-based bio-oil feedstock via combined esterification and transesterification process, the physiochemical of the bio-oil, and subsequent biodiesel produced. Jatropha bio-oil was characterized to determine its fuel properties. A liquid phase transesterification reaction at 60 min reaction time, 50°C temperature, using a methanol-oil molar ratio of 40:1 and 0.35 g of sodium hydroxide (NaOH) catalyst was carried …

Biocatalytic Process by Biodiesel Production to the help of Environment
Abstract: The synthesis of fatty acid esters using vegetable oils seems to be a crucial process that yields good diesel fuel substitutes and useful oleochemical intermediates. Biodiesel is made from fatty acid methyl esters, which are a mixture of mono-alkyl esters produced from vegetable oils including sunflower oil, soyabean oil, rapeseed oil, peanut oil, cotton seed oil, and animal fats like pig fats and lard. Biodiesel can also be made from …

Production and Properties Estimation of Algal Biodiesel
Abstract: The current study examines the production of biodiesel from algal biomass. The investigation was conducted to identify the optimum conditions for oil extraction and transesterification. Solvent extraction method with hexane/isopropanol as a solvent was used for oil extraction. Extracted algal oil was converted into biodiesel with conventional transesterification process, maximum yield was obtained at 1:6 molar ratio with 1 % concentration of NaOH as catalyst at 65°C. The systematic physio-chemical …

Mechanistic and Catalytic Behavior of Os(VIII) for the Chlorpheniramine Maleate and Bromamine-B Redox System: A Kinetics Based Approach
Abstract: Chlorpheniramine maleate (CPM) is an important antihistamine agent. To the best of our knowledge there is no report in the literature about the oxidation of CPM with halogen + 1 oxidant from the stand point of its kinetics and mechanistic chemistry. Hence, a systematic kinetics and mechanistic study on the oxidation of CPM with bromamine-B (BAB) in the presence of NaOH and Os(VIII) catalyst has been carried out at 303 …

Productions and Characterization of Biodiesel by Base Catalyzed Transesterification Reaction from Dairy Waste Scum of DEI Dairy, Agra
Abstract: With the increase in prices and rapid depletion of petroleum-based fuels, the investigation is being done to look over an alternative fuel source. Presently, the biodiesel is mainly produced from vegetable sources such as jatropa oil, karanja oil, rapeseed, soybean, and others that could overlap with nutritional requirement of the society if produced at large scale. Also, the production cost of biodiesel from vegetable and animal sources is very high …

Synthesis of Biodiesel from Biowaste/Vegetable Oil by Using Heterogeneous Nano-Catalyst
Abstract: This paper presents preparation of heterogeneous nanocatalyst (NaOH/ZnO-Li2CO3) for biodiesel synthesis from biowaste/vegetable oil by transesterification. Transesterification is an important reaction that produces fatty acid methyl esters which are excellent substitutes for diesel fuel. Biodiesel production by using nanocatalyst is one of important approaches in the biofuel research. The optimization of transesterification reaction is affected by the catalyst type, reaction temperature, reaction time, methanol to biowaste/oil ratio. The analysis of …

Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Catalytic Trends of OsO4 for the Taurine-Bromamine-T Redox System: Kinetic and Mechanistic Chemistry of Catalyzed and Uncatalyzed Reactions
Abstract: Taurine (2-ethane aminosulfonic acid) facilitates as a building block for protein synthesis, also possessing various other vital biological functions. Literature survey revealed that there was no report available on the oxidation of taurine with any oxidants from its kinetic, mechanistic and catalytic aspects. A detailed comparative mechanistic study of its Os(VIII) catalyzed and uncatalyzed oxidation kinetics by bromamine-T (BAT) in NaOH medium at 313 K revealed the rate law to …
