The method of making ethyl acetate from ethanol and acetic acid
Now there is a method of making ethyl acetate from ethanol and acetic acid. Ethanol is the main component of wine, and acetic acid is the main cause of sour taste in vinegar. When the two meet, ethyl acetate can be synthesized. This ester has a fragrant taste and is widely used in flavors, solvents and other industries.

The method often uses sulfuric acid as a catalyst. Sulfuric acid has strong catalytic ability and can speed up the reaction of this synthesis. First take an appropriate amount of ethanol and acetic acid, put them in a container, and add a little sulfuric acid. The device must be temperature-resistant to prevent heat changes during the reaction.

Heat the device, but not overheat, and it should be controlled at a suitable temperature. When hot, the speed of ethanol and acetic acid molecules collides and combines. The corresponding formula is: ethanol and acetic acid are catalyzed by sulfuric acid, ethyl acetate and water.

During the reaction, there may be side reactions. If ethanol is heated or dehydrated into alkenes, it is essential to control the temperature and the amount of catalyst. After the reaction is completed, the product is mixed with ethanol, acetic acid, and catalyst sulfuric acid.

To obtain pure ethyl acetate, a separation technique is required. First, the sulfuric acid and the unmixed acetic acid are removed by neutralization. An appropriate amount of base, such as sodium carbonate solution, can be added to make the acid-base phase and. At this time, sodium carbonate is combined with sulfuric acid and acetic acid to produce soluble salts.

Then, by the method of liquid separation, the lower aqueous phase is separated, and the upper layer is the organic phase containing ethyl acetate. However, this organic phase still contains trace amounts of water and unpurified impurities. A desiccant, such as anhydrous magnesium sulfate, can be used to absorb the water in it.

Finally, by distillation, according to the boiling point of each substance, to obtain pure ethyl acetate. Ethyl acetate has a low boiling point, is heated and distilled, it is first vaporized, condensed and reduced to a liquid, and is collected to obtain pure and usable ethyl acetate.
