Esterification Of Butyl Ethanoate Lab Report

1261 Words6 Pages

The Esterification of Butyl Ethanoate Aim: The aim of this experiment is to investigate the production of the ester, butyl ethanoate. Introduction: Esters have distinctive odours and flavours, therefore are heavily used in artificial flavourings and fragrances. These odours can range from pineapple, pear, strawberry, banana, cinnamon, lemon, apricot, cherry, raspberry, butter cream, peppermint, orange, honey and much more (Newworldencyclopedia.org).Like all organic compounds esters can be categorized due to the unique functional group. This functional group is written as R-COO-R’ and is pictured on the right: (LAB BOOK) The production of an ester is known as the process of esterification. The two reactants present in the esterification process are the functional groups; carboxylic acid and alcohol. This reaction can be catalysed by the presence of H+ ions, often sulphuric acid is used. This type of esterification, where carboxylic acid and alcohol with an acid catalyst are used is known as the Fischer esterification. This is the type of esterification process which will be undertaken within this experiment, where 4mL of concentrated sulphuric acid will be used to speed up the reaction. It is also important to note that the esterification reaction can also include reactions of; an acyl halide …show more content…

Butyl ethanoate has a fruity smell and can be described as a pear smell. Its molecular formula is CH3COOCH2CH2CH2CH3 and, like in this experiment can be produced from butanol and acetic acid. Butyl ethanoate is a colourless, flammable liquid which often is used in organic chemistry as a solvent. In industry, butyl ethanoate is used to manufacture lacquers, artificial leather, photographic films, plastics and safety glasses. Due it it’s fruity, pear odour it is used in flavouring and fragrance, however at extremely high concentrations butyl ethanoate is toxic

    Bromination of (E)-Stilbene Kaisha Butz Lab Partner: Jenna Knafo Instructor: Dr. Beatrix Aukszi LA: Paige Swalley 10/28/2014 Abstract: The purpose of this experiment was to synthesize the second intermediate (meso-stilbene dibromide) in the E-Stilbene reaction by Bromination. It was hypothesized that if the reaction was heated at 120°C for five minutes the reaction between E-stilbene and the pyridium bromide perbromide would occur, and meso-stilbene would be created. After the reaction occurred the results were analyzed by IR and by an ignition test.

    One of the most important aspects of this experiment is to add the reagents in the specific order. First, the acetone and base solution is added and allowed time to react. This time lapse allows for the formation of carbanions. If all of the reagents were added at the same time, some carbanions would form, and some Cannizzaro products would form as well. Since benzaldehyde was not added until after the carbanion formation, the Cannizzaro reaction should not have happened.

    The goal of experiment four was to use sodium dichromate to oxidize borneol to camphor. To purify the camphor use sublimation, then reduce camphor to isomeric alcohol isoborneol with sodium borohydride. Use the 1H NMR to determine the ratio of borneol to isoborneol in the final product. The experiment was carried out by using sodium dichromate to oxidize a borneol solution that was made with borneol and ethyl acetate. Once the reaction was complete the mixture was transferred into a separatory funnel where the ether and aqueous layers were separated and the aqueous layer was then extracted with two portions of ether.

    Introduction: In this experiment, the identity and absolute configuration of an unknown chiral secondary alcohol will be determined using NMR and CEC. By using the given NMR data, the identity of the alcohol an be determined. In order to identify the stereochemistry of the alcohol, it will have to undergo an esterification reaction in which propionic anhydride, two enantiomers of HBTM(each used in different reactions), and triethylamine are used. Thin layer chromatography will be run at a specified time in the reaction, and the results will be examined both quantitatively(via ImageJ) and qualitatively to which reaction reacted more quickly.

    Abstract In this experiment, the reaction kinetics of the hydrolysis of t-butyl chloride, (CH3)3CCl, was studied. The experiment was to determine the rate constant of the reaction, as well as the effects of solvent composition on the rate of reaction. A 50/50 V/V isopropanol/water solvent mixture was prepared and 1cm3 of (CH3)3CCl was added. At specific instances, aliquots of the reaction mixture were withdrawn and quenched with acetone.

  • Dehydration Of 2-Methylcyclohexanol Lab Report

    Dehydration of 2-Methylcyclohexanol Sura Abedali Wednesday 2:00 PM January 31, 2018 Introduction: Dehydration reactions are important processes to convert alcohols into alkenes. It is a type of elimination reaction that removes an “-OH” group from one carbon molecule and a hydrogen from a neighboring carbon, thus releasing them as a water molecule (H2O) and forming a pi bond between the two carbons1. In this experiment, 2-methylcyclohexanol undergoes dehydration to form three possible products: methylenecylcohexane, 1-methylcyclohexene, and 3-methylcyclohexene in a Hickman still apparatus. Adding 85% Phosphoric Acid to protonates the “-OH” group, turning it into a better leaving group and initiating the dehydration reaction.

  • Isolating Trimyristin To Yield Myristic Acid

    There are three main types of ester hydrolysis reactions: base-facilitated hydrolysis (saponification), acid-catalyzed hydrolysis (with the reverse reaction the Fischer Esterification), and enzymatic hydrolysis, triggered by lipases. Base-facilitated hydrolysis generally uses aqueous NaOH as a reagent, providing the base that attacks the carbonyl and begins the hydrolysis. Saponification hydrolyzes esters into carboxylic acids or fatty acids and alcohols. This has been used for thousands of years to produce soap from fatty acids as the salts produced from saponification can dissolve fats, surrounding them with micelles and allowing them to be easily removed with water1. It can also be used to produce glycerol from triglycerides.
