As an organic compound, glacial acetic acid has a very wide range of applications, but it can be divided into two types, one is applicable to industry, the other is applied to the food industry. What we are familiar with is the vinegar we often eat. Its sour taste mainly comes from glacial acetic acid. Today, we will talk about the role of glacial acetic acid, and hope that relevant knowledge can help friends!

冰醋酸的工业用途，它主要用于醋酸乙烯、醋酐、醋酸纤维、醋酸酯和金属醋酸盐等，用作农药、医药和染料等工业的溶剂和原料。另外，冰醋酸在药品制造、织物印染和橡胶工业中都有广泛用途。它是重要的有机化工原料，在有机化学工业中处于重要地位。

The industrial use of glacial acetic acid, which is mainly used in vinyl acetate, acetic anhydride, acetate fiber, acetate and metal acetate, as well as as solvent and raw material for pesticide, medicine and dye industries. In addition, glacial acetic acid is widely used in pharmaceutical manufacturing, textile printing and dyeing and rubber industry. It is an important organic chemical raw material and plays an important role in the organic chemical industry.

冰醋酸作用于食品界，它可作为酸味剂、增香剂，可生产合成食用醋，这种合成食用醋与酿造醋相似，但是做法要简单很多。他只需用水将乙酸稀释４－５％浓度，添加各种调味剂就可以变成食用醋，常用于番茄调味酱、醉米糖酱、蛋黄酱、泡菜、干酪、糖食制品等。

Glacial acetic acid acts in the food industry. It can be used as a sour taste agent and aroma enhancer to produce synthetic edible vinegar. This synthetic edible vinegar is similar to brewing vinegar, but the practice is much simpler. He only needs to dilute acetic acid to 4-5% concentration with water, and add various flavoring agents to turn it into edible vinegar, which is commonly used in tomato sauce, drunk rice sugar sauce, mayonnaise, pickles, cheese, sugar food products, etc.

冰醋酸的作用还可用于洗涤界。洗涤通常用的冰醋酸，浓度一般为２８％，５６％，９９％，如果买的是冰醋酸，把２８ＣＣ的冰醋酸加到７２ＣＣ的水里，就可得到２８％的醋酸。５６％的醋酸加上同量的水，就可得到２８％的醋酸。浓度大干２８％的醋酸会损坏醋酸纤维和代纳尔纤雏。２８％的醋酸具有挥发性，２８％的醋酸也可以中和碱，他常用来减少由丹宁复合物、茶、咖啡、果计、软饮料以及啤酒造成的黄渍。

The role of glacial acetic acid can also be used in the washing industry. The concentration of glacial acetic acid commonly used for washing is 28%, 56% and 99%. If you buy glacial acetic acid, add 28CC glacial acetic acid to 72CC water to get 28% acetic acid. 56% acetic acid plus the same amount of water can give 28% acetic acid. Acetic acid with a concentration of 28% will damage acetate fiber and denal fiber. 28% acetic acid is volatile, and 28% acetic acid can also neutralize alkali. It is often used to reduce yellow stains caused by tannin compounds, tea, coffee, fruit counters, soft drinks and beer.

通过以上信息我们可以看出，冰醋酸的作用与用途是非常广泛的，冰醋酸还是一种重要的化学试剂，无论他作用于哪种用途，都要根据使用量按需添加。人体如果直接接触高浓度冰醋酸，则会对健康带来严重的影响，轻者对眼睛有强烈的刺激作用，重者可引起化学灼伤。

From the above information, we can see that glacial acetic acid has a wide range of functions and uses. As an important chemical reagent, glacial acetic acid should be added as needed according to the amount of use, no matter what kind of use it is used for. If the human body is directly exposed to high concentration of glacial acetic acid, it will have a serious impact on health. Light people may have a strong irritation on the eyes, and severe people may cause chemical burns.
