  -title: "Esterification"
  -description: """
    <p>In an esterification reaction, a carboxylic acid reacts with an alcohol to form an ester and water.</p>\r\n
    \r\n
    <p><strong>Carboxylic acid + Alcohol &nbsp;</strong>&harr;<strong>&nbsp; Ester + Water</strong></p>\r\n
    \r\n
    <p>Esters consist of two hydrocarbon chains, as labelled R-COOH (for the carboxyl group) and R&#39;-OH (for the hydroxyl group) in this simulation. Esters are natural organic compounds with broad applications in biology (Phosphodiester bounds, fruit flavor), chemistry, industry (soaps, artificial flavors and aromas).</p>\r\n
    \r\n
    <p>An ester&#39;s name is based on the name for the acid followed by the suffix -oate.</p>\r\n
    \r\n
    <p>For example:</p>\r\n
    \r\n
    <ul>\r\n
    \t<li>Ethanoic acid reacts with methanol to form methyl ethanoate and water.</li>\r\n
    \t<li>Propanoic acid reacts with ethanol to form ethyl propanate and water.</li>\r\n
    </ul>

    <p><strong>Carboxylic acid + Alcohol</strong>&nbsp;&harr;&nbsp;<strong>Ester + Water</strong></p>\r\n
    \r\n
    <p>The esterification reaction is <strong>reversible</strong>. This means that ester can recombine with water to (re)produce the acid and alcohol.&nbsp;This reaction is called an <strong>hydrolysis</strong>.</p>\r\n
    \r\n
    <p>As a result, esterification is a (very) slow reaction which never goes to completion. The mixture of carboxylic acid and alcohol as described in this simulation will yield an equilibrium mixture that is 66% ester. Higher temperature will speed up the reaction&#39;s rate, as well as the introduction of a <strong>catalyst </strong>such like sulfuric acid, but the yield of the ester remains unchanged (66%).</p>\r\n
    \r\n
    <p>We can shift the chemical equilibrium in favor of further esterification by removing water as it is formed. This is the principle of the <strong>Dean Stark apparatus </strong>(simulation&nbsp;<a href="../media/107-dean-stark-apparatus" target="_blank">here</a>) which is a used to improve the yield of the ester.</p>
