The reaction of ethanol and acetic acid requires catalytic assistance, usually sulfuric acid. Take sulfuric acid, put it into the mixture of ethanol and acetic acid, and note that it should not be mixed, in order to prevent the local temperature from being high and causing the reaction to go out of control.
Mix well, and set the mixture on the appropriate one. Add the oil, it is appropriate to add the oil slowly with a low fire, so that the temperature level rises, do not add the oil, it is not easy to cause the side reaction, causing the oil to not go out of control. The purpose of adding water is to speed up the reaction rate, so that ethanol and acetic acid can be fully reversed to form ethyl acetate.
In the reaction process, a condensation flow system needs to be set up. This system can make the reaction material of the water flow back into the reaction vessel, so as to improve the utilization rate of raw materials. After the reaction process for a period of time, it is found that there is a clear liquid in the container. The liquid above is ethyl acetate.
This can be carefully separated from ethyl acetate with a separation funnel. However, the ethyl acetate in the reaction, or containing unreacted ethanol, acetic acid and catalytic sulfuric acid, etc. The ethyl acetate obtained by the reaction needs to be improved. It can be washed with a solution of water and carbonate to neutralize acetic acid, dissolve ethanol, and reduce the solubility of ethyl acetate. Wash the washlet, then dispense the liquid, take the washlet phase. Then use sulfuric acid and other water to remove the remaining moisture. The most important operation is to collect the washlet of a specific boiling water to obtain the ethyl acetate of the washlet.

What are the storage conditions for methyl 2-chloro-5-iodine-3-pyridinecarboxylate?
"Tiangong Kaiwu" says: Where the calender is the operator, first dye the tissue paper with aluminium water and wait for it to dry. Press it flat with stone, and use wood vertebrae to make it bright and translucent. The alum used for dyeing the paper, that is, green alum, also known as soap alum, is the crystal of ferrous sulfate. And if you want to preserve its ethyl acetate, you need to pay attention to everything.
Ethyl acetate, volatile and flammable. Therefore, when storing, the first heavy seal. When storing it in a glass bottle, the plug must be tight to prevent it from escaping into the air. This is because if ethyl acetate is exposed, it is not only easy to cause loss, but also the volatile gas is unfavorable to the environment and people.
Second, when avoiding heat. It should be placed in a cool place, away from fire and heat sources. Due to its low ignition point, it is easy to cause combustion or even explosion when heated, which endangers the safety of the surrounding area.
Furthermore, it is necessary to prevent oxidation. Although ethyl acetate is relatively stable, it may be in contact with air for a long time, or it may be affected by oxidation to cause quality changes. Good sealing can reduce air contact and slow down its oxidation process.
And because of its solubility to certain materials, it is not suitable to store it in plastic containers to prevent corrosion and leakage of the container. It is advisable to choose containers with stable chemical properties such as glass. In this way, ethyl acetate should be properly stored for later use.
