    Glacial acetic acid, in other words Aanhydrous acetic acid, is an organic compound. It solidifies at low temperature, with an ice-like shape. The acetic acid with a purity over 98% can be considered as pure acetic acid, whose state is liquid above 14℃ , and solid below 14 ℃. This kind of acetic acid is usually called glacial acetic acid because its solid state looks like ice. Anti-freezing measures should be considered, even in the weather warmer than ice-frozen days, in winter in the north.

    Uses
    An important basic chemical, Acetic acid is an organic compound widely used in the organic synthesis industry, showing its importance of application in heavy chemistry, food, pharmaceutics, cosmetics, pesticides and other industries. Food-grade acetic acid can be used as acidity regulator, acidifying agent, pickling agent, flavoring agent, etc. It can also inhibit the growth of microorganisms in food.

    It is often used in tomato sauce, mayonnaise, drunken glacial sugar sauce, pickles, cheese, sugar products, etc. When properly diluted, it can also be used to make canned food like tomatoes, asparagus, baby food, sardines, squid, and so on, as well as sour cucumber, broth, cold drinks, and sour cheese. When used in spices, it needs to dilute, can be used in production of soft drinks, cold drinks, candy, baked food, puddings, gum, condiments etc. As an acidity regulator, it can be used to make beverages, cans, etc.
