Isoamyl acetate synthesis from fischer reaction
This whole reaction was first done and called the fischer esterification the general reaction scheme can be seen above in the experiment, isopentyl alcohol and acetic acid react in the presence of sulfuric acid to form isopentyl acetate. This fischer esterification reaction reaches equilibrium after a few hours of refluxing silver acetate 1-bromo-3-methylbutane isoamyl acetate synthesis of n . The reaction, called fischer esterification, occurs when an alcohol, in this case isoamyl alcohol, reacts with a carboxylic acid, glacial acetic acid here with the help of heat and an acid catalyst, an ester is formed. For example, low temperatures (~10 °c) favor the synthesis of fruit esters, such as isoamyl, isobutyl, and hexyl acetates, whereas higher temperatures (15–20 °c) promote the production of higher-molecular-weight esters, such as ethyl octanoate, ethyl decanoate, and phenethyl acetate (killian and ough, 1979) higher temperatures also tend to .
