For example, the content of ethyl acetate in a brand of nail polish remover can reach 70%, which can completely dissolve nail polish within 30 seconds.
There are many methods for the synthesis of ethyl acetate, for example, it can be prepared by the reaction of acetic acid or its derivatives with ethanol, and it can be synthesized by the reaction of sodium triacontanate with haloethane. The most commonly used method is the direct esterification of acetic acid and ethanol under acid catalysis. Concentrated sulfuric acid, hydrogen chloride, p-toluenesulfonic acid or strong acidic cation exchange resin are commonly used as catalysts. If Minglv has a value in acid, its dosage is 0.3% of alcohol. The reaction is:
Esterification is a reversible reaction, and the measures to improve the yield are: on the one hand, add excessive ethanol, on the other hand, continuously evaporate the product and water generated during the reaction process, and promote the balance to move towards the formation of copperlite. However, the boiling point of the azeotrope of ester and water or ethanol is close to that of ethanol. In order to evaporate the generated ester and water, the fork is used as little as possible to evaporate the ethanase. In this experiment, a longer fractionating column is used for fractionation.
Ethyl acetate is easy to hydrolyze, and it will gradually hydrolyze to acetic acid and ethanol in the presence of water at room temperature. The addition of trace acid or base can promote the hydrolysis reaction. The biggest difference between alkaline hydrolysis and acidic hydrolysis of ethyl acetate is that alkaline hydrolysis is irreversible, that is, the reversible process and irreversible process in the reaction mechanism. Acetic acid reacts reversibly with ethanol to produce Ethyl Acetate Liquid. Old wine tastes good because a small amount of acetic acid in the wine reacts with ethanol to produce ethyl acetate with fruit flavor.
