Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

Abstract Isopentyl acetate was synthesized in 44.9% yield through a reaction between isopentyl alcohol and acetic acid‚ with sulfuric acid as a catalyst. Identify and purity of the product was confirmed by infrared spectrum analysis of the product and the boiling point (141-142˚C) to the published value of (lit1142.5 ˚C). Procedure: Isopentyl alcohol (.893g)‚ acetic acid (2ml)‚ and concentrated sulfuric acid (4 drops) was added to a 5ml conical vial‚ and then attached to a reflux apparatus.

Synthesis of Isopentyl Acetate Abstract Isopentyl acetate was synthesized via a Fischer Esterification and purified via simple distillation. The yield was determined to be 25%. The identity and purity of the product was confirmed by comparison of the measured ultra-micro boiling point (140°C) to the published value (142°C).1 Chemical Equation Procedure Isopentyl alcohol (0.787 g‚ 1.2 mL‚ 8.93 mmol)‚ acetic acid (1.574 g‚ 1.5 mL‚ 26.20 mmol)‚ and sulfuric acid (0.368

INTRODUCTION Isopentyl acetate‚ "banana oil"‚ is a naturally occurring compound that possesses a distinctive odor. It is found in bananas‚ as well as many other organisms. This experiment attempts to produce isopentyl acetate by heating under reflux‚ which involves heating the mixture in a flask with a condenser placed vertically in the neck since any escaping vapours condense and run back into the flask‚ by combining isopentyl alcohol with acetic acid and an acid catalyst. The product was isolated

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 the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The
