    Chris CXXXX Organic Chemistry Lab Dr. Lyn XXXX 2 February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This

    Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

    Abstract The purpose of this experiment is to synthesize isopentyl acetate via an esterification reaction between glacial acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed using sodium bicarbonate and water‚ then dried with anhydrous sodium sulfate. It was then distilled using a standard simple distillation apparatus. The percent yield of isopentyl acetate was 60.39%. This may have been low due to incomplete distillation or evaporation once

    5.1 MANUFACTURING PROCESSES: Acetone is produced directly or indirectly by propylene. Early processes for the manufacture of acetone were based on the thermal decomposition of calcium acetate or the carbohydrate fermentation of corn starch or molasses. The ready availability of propylene in the 1960s led to routes based on the dehydrogenation of isopropyl alcohol or cumene peroxidation. (1) By Cumene Oxidation (Hock Process). Propene is added to benzene [71-43-2] to form cumene [98-82-8]‚ which
