the gums for the flavor. The reaction that takes place in this experiment is a esterification. In this experiment‚ the carboxyl group of the acetic acid joins with the hydroxyl group of the isopently alcohol‚ catalyzed by the presence of sulfuric acid‚ through a dehydration reaction‚ in which water is removed. This allows for an ester bond to form in the second carbon of the isopentyl acetate (banana oil). Esterification of the acetic acid with isopentyl alcohol is the reaction‚ which prepared the

Experiment 13B: Isopentyl Acetate (Banana Oil) Semimicroscale Procedure Taylor Levin 5.28.14 Chemistry 352- Organic Chemistry Lab Summer 2014 Purpose: To prepare isopentyl acetate (banana oil)‚ an ester‚ from isopentyl alcohol and acetic acid through the Fischer Esterification reaction. Reactions: acetic acid + isopentyl alcohol isopentyl acetate + water C2H4O2 + C5H120 CH3COOCH2CH2CH(CH3)2 + H20 Procedure: A reflux condenser was assembled

2013 Abstract The purpose of this lab was to determine whether a sufficiently pure sample of synthetic banana oil could be prepared through Fisher Esterification. During the experiment‚ the reaction mixture was purified through an extraction workup‚ and according to the instructor‚ once getting the density of the product and the actual yield; it was not required to use the distillation method.

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic acid‚ we are able to create acetylsalicylic acid otherwise known as aspirin as well as methyl salicylate‚ which is a component of oil of wintergreen. Both of which are used for pain relief/soreness. Salicylic

Introduction Generally‚ PET can be produced in two steps by one of two ways‚ called the DMT and the TPA processes‚ or the transesterfication and direct esterification routes‚ respectively. Since its commercialization in the 1950’s by DuPont‚ PET was predominantly synthesized out of DMT due to the fact that this monomer‚ compared to TPA‚ was relatively easily purified by distillation. Yet‚ since the 1960’s‚ purified TPA became available by the development of new technologies and gained a lot of importance

amounts of starting material in the product‚ which is okay in small amounts‚ but we need to test the product to see if it is within their acceptable ranges to be used. We will be synthesizing synthetic banana oil‚ or otherwise known as isopentyl acetate. We will synthesize thie oil by combining isopentyl alcohol with acetic acid and sulfuric acid‚ and heating under reflux for one hour. After this time‚ we will separate and purify our product via washing with sodium bicarbonate (that separates compounds
