What is tartaric acid

when it comes to tartaric acid, many people may be full of doubts, because this is generally a professional problem, so most people do not understand it, and most people will not encounter it in their life, which is more reasonable. But sometimes we hear the name tartaric acid on some occasions, but we may be ridiculed as ignorant because we don’t know it, so we have to keep learning new knowledge.

tartaric acid is a kind of acid. In fact, many plants have tartaric acid. For example, grapes we often eat in summer contain a lot of tartaric acid. But just say that, many people still can’t understand it very well. So, let’s give a detailed introduction to what tartaric acid is.

tartaric acid (2,3-dihydroxysuccinic acid) is a kind of carboxylic acid, which exists in many plants, such as grapes and tamarinds. It is also one of the main organic acids in wine. As an antioxidant in food, it can make food sour. The most important use of tartaric acid is beverage additive. It is also the raw material of pharmaceutical industry. Tartaric acid is an important auxiliary and reducing agent in the mirror making industry, which can control the formation rate of silver mirror and obtain a very uniform coating.

tartaric acid is also known as 2,3-dihydroxysuccinic acid. The simple structure is hooch (OH) ch (OH) COOH. Potassium hydrogen tartrate exists in grape juice, which is difficult to dissolve in water and ethanol. It precipitates in the process of grape juice brewing, which is called tartaric acid. Tartaric acid mainly exists in the form of potassium salt in a variety of plants and fruits, and a small amount exists in the free state.

tartaric acid is dihydroxysuccinic acid. There are two asymmetric carbon atoms and three stereoisomers, namely, dextral (D-type, L-type), left-handed (L-type, D-type) and racemic. Generally, racemic tartaric acid is also called gluconic acid. D-tartaric acid is widely distributed in higher plants as free or K, Ca and Mg salts, especially in fruits and leaves. In the manufacture of wine, a large amount of tartar (hydrogen potassium salt) is deposited. In addition, it is also common in molds and lichens. The isolated tartaric acid fermenting bacteria (the mutant strain of gluconoba ctersuboxydans) are decomposed by glucose oxidation in vivo. Through 5-ketoglucosic acid, tartaric acid is formed while glycolic acid is formed. Ammonium tartrate can be changed into Succinic Acid by microorganism. Therefore, tartaric acid is used as raw material for succinic acid production in industry. L. pasteus used tartaric acid as a material for studying the optical activity of natural substances, which is very famous in history.

the biggest use of tartaric acid is beverage additive. Then there are the raw materials for the pharmaceutical industry. It is a very important chiral ligand and chiral molecule in modern organic synthesis. It can be used to prepare many famous chiral catalysts and as chiral source to synthesize complex natural product molecules. Tartaric acid is also an antioxidant, which has been used in food industry. It can be used as deoxidizer in biochemical test.

through the above detailed introduction of tartaric acid, I believe that most people now have a certain degree of understanding of tartaric acid, which is good for us. If we need to use tartaric acid in our daily life, we will know how to operate, not just at a loss.
