preparation of isopentyl acetate :: essays research papers

Pear oil commonly refers to a solution of isoamyl acetate in ethanol that is used as an artificial flavor.; Isoamyl acetate, also known as isopentyl acetate, is an organic compound that is the ester formed from isoamyl alcohol and acetic acid.

Since isopentyl acetate is soluble in diethyl ether, but acetic acid is soluble in both solvents.

Therefore, simply mixing equal amounts of the starting materials will convert only about 67% of the starting material into product.
To drive the equilibrium forward Le Chatelier's principle is used, in this case there are two ways to adjust reagent concentrations to force isopentyl alcohol to become isopentyl acetate.

15 mL of isopentyl alcohol and 20 mL of glacial acetic acid were added to the flask.

It is found in bananas, as well as many other organisms.
This experiment attempts to produce isopentyl acetate by heating under reflux, which involves heating the mixture in a flask with a condenser placed vertically in the neck since any escaping vapours condense and run back into the flask, by combining isopentyl alcohol with acetic acid and an acid catalyst.
