Solution of acetic acid crystallization at low temperature in winter

Acetic acid, also known as acetic acid, glacial acetic acid, chemical formula CH3COOH, is an organic monobasic acid, which is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6 ℃ (62 ℉). After solidification, it is a colorless crystal with weak acidity and strong corrosiveness in its aqueous solution. Steam has an irritant effect on eyes and nose. The melting point of acetic acid is 16.6 ℃. Generally, crystallization occurs when the temperature is lower than 16 ℃. It affects the production, transportation, storage and use of many enterprises.

 

Acetic acid will crystallize when it is lower than 16 ℃. We can put it in greenhouse, air-conditioning room, workshop with heating and other places where the temperature is high and it will dissolve slowly. The method of external warm water can also be used for thawing, but the water temperature should not be too high by this method. Various factors such as packaging should be taken into consideration, and special personnel should be assigned to watch, so as to avoid unnecessary losses.
