On the method of ethyl ester reagent
All kinds of things in the world, there are different methods of preparation, and ethyl ester reagent also has its own way. If you want to get this agent, you should first understand the rationale, and then proceed with the method.

For ethyl ester, it is made of acetic acid and ethanol. If the two are in harmony, you need to adapt their temperature and control the time. If the temperature is not appropriate, it may cause the reaction to be delayed, or make the product impure; if the time is not right, it will not be a good product.

Take an appropriate amount of ethanol first, put it in a clean vessel, and slowly inject acetic acid, stirring constantly in the meantime, so that the two are blended. Then add catalytic agents, sulfuric acid and the like. The amount should be careful, too much will damage the product, and too little will be insufficient to

Prepare all kinds of things, put them in the kettle, and slow down the heat. The kettle is covered with a condenser, so that the escaping gas can be returned to the kettle to avoid material loss. Looking at the reaction, when the temperature is constant and the gas is stopped, it can be seen that the reaction will be completed.

Then take the resulting liquid and wash it with water to remove its impurities. Then use the method of salting out to separate the ethyl ester, float it on the water, and remove the water to obtain a pure ethyl ester reagent.

Although this method is simple, the steps are complicated, and it must be done with caution. If there is a slight difference, it is difficult to form a good agent. Therefore, workers should be familiar with their hearts, abide by their laws, and abide by their regulations in order to produce excellent ethyl ester reagents for all their needs.
