The theory of gallic acid, the core product of hydrolysis of vanadic acid
There is a factory in Guangdong, called "Xuandong Chemical", specializing in the chemical industry. It is made by the hydrolysis of vanadic acid, and the core is gallic acid, which has extraordinary functions in chemical industry.

Guanfu gallic acid, which originates from the subtle changes in the hydrolysis of vanadic acid. Vanadic acid, in a specific environment, is hydrolyzed in contact with water, during which the clutch of molecules and the reorganization of atoms are like a subtle dance. At the beginning of hydrolysis, the structure of vanadic acid is gradually disassembled, and oxygen atoms, vanadium atoms and water molecules interact to form an intermediate product. This intermediate product is non-stationary, its activity is abnormal, and after a series of complex reactions, it finally becomes gallic acid.

Gallic acid, in the shape of fine crystals, or powder, light in color, white or yellowish. Its mild nature is often a key factor in many chemical reactions. In medicine, it has antibacterial and anti-inflammatory properties. Because of the molecular configuration of gallic acid, it can interact with the cell wall and cell membrane of bacteria, disturbing their metabolism and inhibiting their growth and reproduction. In ancient medical books, there is also a similar theory. Although the words are simple, the pharmacology is the same.

In the industry of printing and dyeing, gallic acid is a good agent for enhancing color. Fabrics are treated with it, and the color is bright and long-lasting. This is because gallic acid can tightly bind to fabric fibers and absorb dye molecules at the same time, making the dye more firmly fixed. Printing and dyeing craftsmen in the past, although they did not understand its chemical principles, through generations of exploration, they also knew that the juice of certain plants and trees (containing similar ingredients) can enhance the color of cloth and silk, which is in fact similar to the application of gallic acid today.

Furthermore, in the food industry, gallic acid can be used as a preservative. It can delay the spoilage of food and maintain its fresh quality. Because it can inhibit the activity of microorganisms, it builds a protective wall in the microscopic world of food. If you want to store food in ancient times, you can also use natural preservatives. Today's gallic acid can be said to be the progress of science and technology.

In Xuandong Chemical Factory, in order to obtain pure gallic acid, the process is complicated and fine. Since the beginning of the hydrolysis of vanadic acid, the temperature, humidity and reaction time have been strictly controlled. After hydrolysis, the impurities are removed and the essence is retained through multiple separation and purification methods. At the time of separation, either filtration is used to separate solid and liquid; or extraction is used to extract the required things between different solvents. When purifying, recrystallization and other means are indispensable, and repeated operations are performed until the purity of gallic acid reaches the standard.

Gallic acid, although it is a microscopic chemical substance, plays a pivotal role in the chemical industry, medicine, printing and dyeing, and food industries. Xuandong Chemical Factory has obtained this core product with exquisite craftsmanship, which has contributed greatly to the development of the industry. In the chemical way, continuous exploration has led to better performance and wider application of gallic acid, which is indeed the good fortune of the chemical industry and the prosperity of the industry.
