Test of ethyl acetate
In ancient times, there were wise men who wanted to understand the physical properties, so they did the test of ethyl acetate. In the clean room, prepare all kinds of things, including utensils and potions, all of which are fine and flawless.

First take an appropriate amount of acetic acid and ethanol, put it in the kettle, and add a little concentrated sulfuric acid. This acid is a catalyst for transformation, and it can respond quickly. The kettle is burned with a warm fire, so that it is slowly heated, and do not let it be impatient.

For a moment, the liquid in the kettle is slightly boiling, bubbles rise, and something gradually emerges. It is like light smoke, scattered in the room, smelling it, and the taste is fragrant and clear. This is the gas of ethyl acetate.

Compound by the method of condensation, so that the gas becomes a liquid and is collected in the bottle. Looking at the liquid, it is clear and colorless, like the purity of jade dew.

After the test, the wise man recorded his feelings in detail, and knew that the combination of the two, after temperature and agent, can form ethyl acetate. Its properties can be used in many places, either as a fragrance or as a solvent, and it is beneficial to people's livelihood and all kinds of industries. The work of this test is not the change of unique things, but also the foundation of things used in later generations.
