Trifluoroacetic acid is a common organic compound, which is widely used in chemical industry, medicine and other fields. The correct preservation method is very important to ensure the quality and safety of trifluoroacetic acid. The following are some precautions about the preservation of trifluoroacetic acid:

1. Avoid direct sunlight: Trifluoroacetic acid will decompose in the sun, so you should avoid direct sunlight when storing, you can choose to use a hood or place it in a cool and dry place.

2. It is strictly prohibited to contact with oxidants: Trifluoroacetic acid has strong corrosiveness, so it should be kept away from oxidants, strong bases and other chemicals to prevent dangerous chemical reactions.

3. Keep sealed: Trifluoroacetic acid volatile, in order to prevent its volatile and pollution of the environment, the container should be kept tightly closed to avoid leakage.

4. Prevent moisture: Trifluoroacetic acid is sensitive to water, easily absorbs water and produces corrosive hydrofluoric acid. In the storage should pay attention to moisture, choose a dry and ventilated environment for preservation.

5. Avoid high temperature: Trifluoroacetic acid will decompose at high temperature, so it should be away from fire and high temperature environment. It is recommended that the storage temperature be controlled below room temperature.

In summary, the correct preservation method is essential for trifluoroacetic acid. I hope everyone can strictly follow the above precautions for preservation and use to ensure the quality and safety of trifluoroacetic acid.
