    and purify isopentyl acetate or banana oil. In order to perform this reaction, the mixture containing excess acetic acid and isopentyl alcohol was heated under reflux. The methods of extraction, drying, and distillation were then used to help purify the isopentyl acetate. After the completion of all these processes, we were able to determine the yield and analyze our isopentyl acetate. Experiment Scheme1 Equation 1. Esterification of acetic acid to form isopentyl acetate. The experiment to

    AIM Design an experiment to study a thermodynamic property of a chemical substance, a chemical reaction, a physical change or chemical phenomenon. BACKGROUND INFORMATION Standard enthalpy change of solution, ∆Hsolnø, is the enthalpy change when one mole of a substance dissolves in water to form a solution of infinite dilution under standard conditions.1 The standard enthalpy change can either be exothermic or endothermic. An exothermic reaction is a reaction where energy is released as a form of

    Dichloro acetate (also known as DCA) has been predicted by many scientists to be the potential alternative cure for cancer since it was found that it killed the human cancer cells in a rat. However some scientists are not sure yet as to whether the treatment is the best solution because the human being studies have not been completed yet. Some scientists are against it because of its harmful side effects such as nerve functions. DCA is the said to be an acid, an analogue of acetic acid in which

    Introduction: Benzopinacol can be prepared from benzophenone in presence of sun light (photochemically) using isopropanol as the reducing agent in presence of acetic acid. Acetic acid is added to prevent the cleavage of benzopinacol to benzophenone and benzhydrol by the alkali derived from the glass container used for the reaction. Benzopinacol obtained in the first experiment is converted to benzopinacolone by heating under reflux (5 minutes) with glacial acetic acid containing trace amount of iodine

    decarboxylation. It is an irreversible oxidative process. Here the carboxyl group is removed from the pyruvate as a molecule of C02 and the remaining two carbons are used to become the acetyl group in the Acetyl-CoA. Therefore pyruvate C3 is converted to acetate c2. In this reaction Coenzyme A is needed. NADH is also created in this reaction. The NADH gives a hydride ion to the respiratory chain.

    The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol, using a strong acid as a catalyst. The product was washed, and distilled. This approach is called Fisher esterification, whereby esters are produced by refluxing a carboxylic acid and an alcohol in the presence of a concentrated acid catalyst. The ester produced had a banana smell odor. The extraction of the crude product was conducted using sodium

If having more sodium acetate in the hand warmer lasts longer with the highest temperatures than having less sodium acetate, then one would simply buys the bigger hand warmer. After making sodium acetate, the liquid was placed into pouches, which would go on to be tested for their temperatures over a certain period of time. The pouches would be activated and placed

    Did you know you can turn sodium acetate into “hot ice”? It is exactly what happens within a chemical heating pack! Inside that pack, along with water, is a solution that has more sodium acetate that can normally be dissolved at room temperature. Sodium acetate is the sodium salt of acetic acid. This solution is called a saturated solution because it contains the maximum amount of sodium acetate that can be dissolved without heating the solution (1). What is in a solution is a solute, which is

    to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with different polarities are used to dissolve and separate different solute components, so they form two distinct liquid layers. In this experiment, ethyl acetate, an organic solvent, and an aqueous solution, were used as the two immiscible solvents. The extraction solvent must be capable of dissolving one of the mixture components, without irreversibly reacting with it. While initially it seems as though the

    decrease in the pH level as the acidic component is formed. The purpose of this experiment is to compare the hydrolysis rates of esters by monitoring the pH values of their aqueous solutions as a function of time. The esters being compared are ethyl acetate, ethyl benzoate, ethyl formate, and ethyl butanoate while the pH level can be determined by the change in color of the solution with the use of sodium hydroxide (NaOH) for the base and the universal pH indicator. The two factors that affect the rates
