Submitted: September 13‚ 2012 ------------------------------------------------- Abstract Carboxylic acid derivatives namely‚ acyl halides‚ acid anhydrides‚ esters and amides were classified through different reactivity tests. The samples used were acetyl chloride for acyl halide group‚ acetic anhydride for acid anhydride group‚ ethyl acetate for ester group‚ acetamide and benzamide for amide group. These derivatives were identified through the mechanism of hydrolysis‚ alcoholysis and aminolysis reactions

on a C-C backbone tends to resist degradation‚ whereas heteroatom-containing polymer backbones confer biodegradability. Biodegradability can‚ therefore‚ be engineered into polymers by the judicious addition of chemical linkages such as anhydride‚ ester‚ or amide bonds‚ among others. The usual mechanism for degradation is by hydrolysis or enzymatic cleavage of the labile heteroatom bonds‚ resulting in a scission of the polymer backbone. Macroorganisms can eat and‚ sometimes‚ digest polymers‚ and also

The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on

Lab 5: Preparation of Synthetic Banana Oil September 20th‚ 2012 Purpose: The main purpose of this experiment was to synthesize banana oil (isopentyl acetate.) Ester are often prepared by the Fischer esterification method‚ which involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst. Theory: Synthesize isopentyl acetate by combining isopentyl alcohol with acetic acid and sulfuric acid and then heating the reaction mixture under reflux for an hour. The alcohol

Flor‚ Lu‚ Ricardo‚ Magdurulan‚ Tricia 2Biology6‚ Department of Biology‚ College of Science‚ UST‚ Manila annalesaca@yahoo.com Abstract Esters are a type of functional group that causes distinguishable flavors or odors of some fruits. It can be synthesized by Fischer reaction‚ which is an acid-catalyzed reaction of an alcohol and carboxylic acid. One of the esters known for its characteristic banana flavor is the isoamyl acetate. By using Fischer reaction‚ Isoamyl acetate was produced by refluxing

Acid Mandy Boyle Chem 213‚ Section 002 Due Date: December 3‚ 2009 I. Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols. Companies such as Dove‚ Palmolive‚ Dial‚ and many others owe their success
