Uses and synthesis of Gallic acid Powder

Gallic acid Powder is a component of hydrolyzable tannins, also known as Gallic acid, chemically known as 3,4,5-trihydroxybenzoic acid.Gallic acid CAS 149-91-7 is found in Yunnan Puerh Tea at relatively high levels, and has a wide range of biological effects such as antimicrobial, anti-inflammatory, anti-tumor, and anti-mutagenic effects in its own right.

Gallic acid Raw Materials, also known as gallic acid or gallic acid, is an organic acid that can be found in plants such as Pentaphyllum officinale, lacquer tree, and tea. Gallic acid Raw Materials is soluble in water, alcohol and ether; it has the properties of phenol (easily oxidized and produces a blue-black precipitate from aqueous ferric chloride) and carboxylic acid (loses carbon dioxide when heated and becomes pyrogallic gallic acid).

Gallic acid CAS 149-91-7 can be used as a developer, and its basic bismuth salt is used as an antiseptic, also used in the pharmaceutical industry.

Applications / Functions of Gallic acid Powder

Gallic acid Powder has many applications in pharmaceuticals, inks, dyes, food, light industry and organic synthesis, etc. Gallic acid Powder produces blue-black precipitate with trivalent iron ions, which is the raw material of blue-black ink; it is also used in tanning; it can be used as photographic developer, etc. Gallic acid Powder propyl ester is an antioxidant, which can be used in edible oils and fats to prevent rancidity and spoilage. Gallic acid Powder propyl ester is an antioxidant, which can be used in edible oils and fats to prevent rancidity. In medicine, Gallic acid Raw Materials is a hemostatic astringent and a mild local irritant.

Gallic acid Raw Materials has antimicrobial properties and can be used to treat bacillary dysentery. It has astringent, hemostatic and antidiarrheal effects. Can be used as an antiseptic. Gallic Acid Raw Materials can be used to prepare pyrogallic gallic acid, drugs, inks, mordant dyes, and explosion-proofing agents, etc. Gallic Acid Raw Materials is also used as a developer and an analytical reagent for the detection of free inorganic acids, dihydroxyacetone, alkaloids, and metals.

• Gallic acid Raw Materials can be used as preservatives and can be used in the preparation of mordant dyestuffs and antiknocking agents.
• Gallic acid Powder can be used as a preservative, can be used to prepare mordant dyes and explosion-proof agents, etc.
• Gallic acid CAS 149-91-7 is mainly used as a coloring agent for blue and black ink. Used in the pharmaceutical industry for the preparation of sulfonamide synergistic drug TMP and used as the coordinating agent of sulfonamide drugs such as SMZ and SDB. It is used in the food industry for the preparation of preservative gallopropyl ester. It is used in the defense industry for the preparation of explosion-proof agent. In addition, Gallic acid CAS 149-91-7 can also be used in the production of mordant dyes and used as a developer.
• Gallic acid CAS 149-91-7 is a water-soluble phenolic acid found in the leaves of grapes and many other plants, and is an effective in vitro antioxidant.

Physicochemical Property of Gallic acid Powder

Gallic acid CAS 149-91-7 White or light brown needle-like crystal or powder. Melting point 235-240°C (decomposition). Loss of water of crystallization when heated to 100-120℃, loss of carbon dioxide when heated to over 200℃ to produce pyrogallic gallic acid (i.e. Lianphentriol). Soluble in hot water, ether, ethanol, acetone and glycerol, insoluble in cold water, insoluble in benzene and chloroform.

Production Methodprocess of Gallic acid Powder

Gallic acid Powder is produced from Pentaphyllum officinale. The main component of Gallic acid is tannic acid, which belongs to hydrolyzed tannin, soluble in hot water, astringent flavor, and a kind of amorphous complex organic matter. China's pentaphyllum tannins are formed by the complex mixture of pentaphyllum acid, dipicolinic acid and glucose combined in the form of glycosides or esters. Tannic acid hydrolysis by pressure that is generated gallic acid and glucose, hydrolysis Mr. into gallic acid ester, and then hydrolyzed by double gallic acid ester gallic acid, the hydrolysis temperature of 133-135 ℃, the pressure of 0.18-0.2MPa. from the pressure to 0.18MPa to start the reaction to maintain the end point of 2h. Compared with normal pressure hydrolysis, sulfuric acid and steam can be saved, and the production capacity can be increased by 25%.
