    (glycerides) and methanol are combined with sodium hydroxide as a catalyst. This causes the oils to break apart and reaction of the oils with the methanol. As seen in Figure 1‚ this produces biodiesel (in the form of esters) and glycerol. Figure 1: The production of biodiesel (esters) from glyceride (cooking oils) and an alcohol (methanol). In combustion‚ a substance can be completely or incompletely combusted. In complete combustion‚ a fuel is combined with oxygen to produce water and carbon dioxide

    powder form of aspirin‚ the process of crystallization was conducted and was run through vacuum filtration. After running through the help of an electronic instrument‚ the result that was achieved in this experiment was met due to the presence of esters in the graph in Figure 5; with a peak of 1297.89 at 1300-1100. There is also a match of 35.48 with ethyl salicylate. The objective‚ which is to create aspirin‚ has been completed due to the results shown by the data provided by an electronic instrument

    3. Results and discussion 3.1 Nutritional analysis In the present study‚ the potential benefits were shown by nutritional attributes of dried bathua (Table1). Moisture content and dry matter analysis‚ reporting during nutritional analysis is very important because it directly affects the nutritional content of vegetable. The moisture content was quite low (5.06%) which may be advantageous in view of increasing the sample’s shelf life. Bathua was found to be rich in carbohydrates (40.84%). There

    used. IODIESEL consists of a mixture of fatty acid alkyl esters‚ that can be used as an alternative fuel in compression-ignition engines; it is obtained from renewable resources‚ such as vegetable oils and animal fats‚ which makes it biodegradable and non-toxic [1]‚[2]. Biodiesel might be produced by transesterification‚ which is a three-step reversible reaction that converts the initial triglyceride into a mixture of alkyl esters and glycerol‚ in the presence of a catalyst. Currently‚ biodiesel

    understanding the chemical transformations. Now‚ we know that this process is a reaction of esters with a strong base such as KOH or NaOH. The esters‚ triglycerides are the main constituents of vegetable oil and animal fats. The triglyceride is a tri-ester come along with 3 long fatty acid hydrocarbon chain. When triglyceride reacts with 3 equivalents strong aqueous base solution such as NaOH or KOH‚ the three ester bonds are hydrolyzed to yield 3 fatty acid salts (soap molecules) and one glycerol. The

    distillation -- and was characterized by its boiling temperature and its refractive index. Esterification is a condensation reaction where two molecules are joined together to form a larger molecule with the simultaneous loss of water. This ester in this experiment is isopentyl acetate formed from acetic acid and isopentyl alcohol. The reaction is catalyzed by hydrochloric acid‚ a Fisher esterification process‚ (McMurry‚ p780-781) but the catalyst affects only the rate of reaction‚ and not
