How to prevent crystallization of barreled glacial acetic acid during storage and use?
Generally, after crystallization, blow it directly with steam.
Acetic acid (ethanoic acid), alias: Acetic acid and glacial acetic acid have a melting point of 16.6°C, a boiling point of 117.9°C, and a relative density of 1.0492. When the temperature is lower than its melting point, it condenses into ice crystals, so it is also called glacial acetic acid. Therefore, it usually crystallizes in winter, which affects its use. Before use, you can blow steam directly into a pit to melt it. But be aware that acetic acid is flammable and its vapor can form an explosive mixture with air. In case of open flame or high heat, it can cause combustion and explosion. ； Contact with chromic acid, sodium peroxide, nitric acid or other oxidants may cause explosion hazard ； Its lower explosion limit is 4.7% and its upper explosion limit is 17.0%. It is a Class A fire hazard medium. And it is corrosive. Take safety precautions.
The glacial acetic acid we use is placed in the heating room in advance and then used.

The water temperature is about 70 degrees Celsius. Before use, put the acetic acid into the sink and heat it for 10 minutes. However, it should be noted that the protection work must be sufficient
Place the bucket in the warm pool to ensure the water is at a constant temperature
