Synthesis of Isopentyl Acetate (Banana Oil) Using a Fischer Esterification Reaction Zhenshu Wang (Stan) TA: Aaron League September 23‚ 2012 Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction

Nucleophilic Substitution | Synthesis of n-Butyl Bromide and t-Pentyl Chloride | | Jessica | [Pick the date] | Abstract The synthesis of the alkyl halide n-Butyl Bromide from alcohol is the foundation for the experiment. During the isolation of the n-butyl bromide‚ the crude product is washed with sulfuric acid‚ water‚ and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with

Introduction: Density is defined by its mass per unit volume‚ and is most often written in mathematical terms as; d = m / v Mass is usually given in grams‚ g‚ and volume is given in cubic centimeters‚ g/cm3‚ or‚ grams per milliliter‚ g/mL. Density is not a property that depends upon the amount of substance present. For example‚ one gram of lead and one ton of lead have the same density. Density also does depend on temperature. For instance cold water is denser than warm water;

Goal(s): To study the effect of concentration on the rate of a reaction‚ and to find the order of the reaction in each reactant and write a rate equation. Background Theory: Chemical reactions occur at different rates that ultimately depend on their concentration‚ the temperature‚ the usage of catalysts‚ the nature of reactants‚ like the surface area of the particles. Concentration‚ for instance‚ increases the number of molecules or particles in a certain volume‚ so collisions will become more

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed
