The method of ethyl ester formation
The ancient method of combining ethyl ester is quite complicated. It is necessary to use acetic acid and ethanol as the quality, and use acid as the medium to combine the phases.

Start, put acetic acid and ethanol in the container, and enter it with sulfuric acid. Sulfuric acid is the agent of the catalyst, which can promote its response without changing itself. Mixing the two, slow down the heat, the fire should not be intense, and the quality may escape and damage the production.

As the temperature gradually rises, the carboxyl group of acetic acid and the hydroxyl group of ethanol exchange their elements, and come out of water, and ethyl ester is formed. The corresponding formula is roughly like this: acetic acid and ethanol meet the acid medium, and the phase combines and water comes out, and ethyl ester is formed.

However, there are also difficulties in this. The water comes out, or it goes against it, so that the production is not much. Therefore, the water is often removed by method, or the water is absorbed with a agent, or it is steamed away, so that the reaction tends to form an ester.

In addition, the temperature and the amount of agent must be fine-tuned. If the temperature is high, the quality will be easy to disperse, and the agent will be more or more. Only by being good at observing the state of response and controlling the temperature and agent in a timely manner can you obtain more and pure ethyl ester. This is why the method of combining ethyl ester is ancient and profound, and it cannot be done well without intensive research.
