Simple Distillation of Ethyl Acetate contaminated with Methyl Violet Operational OrganicChemistry A Problem Solving Approach to the Laboratory Course‚ 4th edition‚ by John Lehman‚ Experiment 4‚ OP-30 pg 710-719 I. Introduction The students will use the distillation method to extract pure Ethyl acetate by using the distillation equipment. The distillation is the process of vaporizing a liquid mixture in one vessel and condensing the vapors into the receiver. II. Experimental procedures. 1

Preparing Esters by esterification method using carboxylic acid to an alcohol‚ which is 1.0 ml of ethanoic acid to the ethanol‚ and ethanoic acid to the propan-1-ol‚ also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound‚ famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester‚ which was known of its smell. However it was expected to have a pleasant smell

Using orange (Citrus sinensis) as an airfreshener Review of related literature: Octyl acetate Octyl acetate‚ or octyl ethanoate‚ is an ester that is formed from octanol (octyl alcohol) and acetic acid. It is mostly found in oranges and other citrus products. Octyl acetate can be synthesized by a condensation reaction: C8H17OH + CH3COOH → C10H20O2 + H2O Uses Because of its fruity odor‚ octyl acetate is used as the basis for artificial flavors and in perfumery. It is also as a solvent for

and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction as a whole shifts the left producing more isoamyl acetate to try and balance the reaction

Fischer Esterification Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/15/03 Abstract: The objective of this experiment is to efficiently perform a fischer esterification of 1-Hexanol to form water and hexyl acetate‚ and to confirm the esterification with a nuclear magnetic resonance (NMR) spectroscopy. It was found that 0.3963 grams hexyl acetate was formed with a percent yield of 33.2%. The product was confirmed using NMR‚ IR‚ and boiling point confirmation. Backround: A Fischer
